QNAP Patched a Major Zero-Day Vulnerability on NAS Devices After Pwn2Own 2024

A new wave of cyber espionage, meticulously crafted through a strategy known as "FakeUpdate," has been targeting users in France, leveraging compromised websites to push fake update notifications for popular applications. 
At the heart of this operation is the sophisticated _"WarmCookie"_ backdoor, deployed by the elusive threat group, [SocGolish](https://www.secureblink.com/cyber-security-news/fake-microsoft-teams-infects-networks-of-various-companies-using-cobalt-strike). 

By disguising itself as legitimate software updates, WarmCookie has gained an unprecedented reach, with the latest enhancements adding layers of complexity and danger to this backdoor.

### WarmCookie's Evolution and Deployment

First identified by cybersecurity firm [eSentire](https://www.esentire.com/blog/esentire-threat-intelligence-malware-analysis-resident-campaign) in mid-2023, WarmCookie quickly distinguished itself with broad, multi-functional capabilities tailored to Windows systems. 

Traditionally, it has spread through phishing emails, often masquerading as job offers. In the current campaign, however, WarmCookie is distributed via FakeUpdate attacks, where fake updates mimic widely trusted applications such as [Google Chrome](https://www.secureblink.com/cyber-security-news/google-chrome-patches-tenth-zero-day-of-2024-exploited-in-the-wild), [Mozilla Firefox](https://www.secureblink.com/cyber-security-news/firefox-hacked-update-now-to-patch-actively-exploited-zero-day), Microsoft Edge, and Java.

The attackers behind WarmCookie are deploying this malware using highly convincing fake update prompts displayed on compromised websites. Once users click the prompts, WarmCookie is silently installed on their systems, enabling the threat actors to take control and harvest valuable data.

### WarmCookie’s Core Capabilities

The technical intricacies of WarmCookie illustrate a calculated approach to data theft and remote control. Its capabilities include:

WarmCookie efficiently locates and exfiltrates files, focusing on sensitive data that can be monetized or weaponized for further attacks.

The malware gathers detailed information about the infected device’s configuration, including hardware, software, and network characteristics, essential for tailoring subsequent attack strategies.

By scanning the Windows Registry, WarmCookie identifies installed applications and system configurations, optimizing its actions based on the system environment.

WarmCookie can execute arbitrary commands, allowing the attackers to alter system files, modify permissions, or introduce additional malware.

The malware has built-in screenshot-capturing abilities, which are instrumental for gathering visual context on the target's activity.

Additional Payload Introduction: Beyond its core functions, WarmCookie serves as a delivery mechanism for secondary payloads, intensifying its impact on compromised systems.


These features not only reinforce WarmCookie’s versatility but also highlight the attackers' ability to adapt to various operational environments.

### Enhancements in the Latest Campaign

The current campaign, monitored by [Gen Threat Labs](https://x.com/GenThreatLabs/status/1840762181668741130), reveals that WarmCookie has been updated with new functionalities that expand its threat scope:

WarmCookie now stores and executes dynamic link libraries (DLLs) from temporary directories, complicating detection by traditional endpoint security solutions.

The backdoor can transfer and run EXE and PowerShell files on infected devices, an enhancement that gives the attackers direct, remote control over system processes.

The malware conducts anti-VM (virtual machine) checks to evade detection by analysts running virtualized environments, ensuring WarmCookie operates only in genuine user environments.


This set of advancements marks a significant evolution in WarmCookie’s architecture, enhancing its ability to persist on targeted systems and effectively resist forensic analysis.

### Infection Chain: Exploiting the FakeUpdate Mechanism

The infection process is both seamless and deceptive. It starts with a fake update notification on a compromised or maliciously designed website. 

Once a user clicks the prompt, JavaScript initiates the download of WarmCookie, disguised as a legitimate installer. This fake installer, once executed, installs WarmCookie on the system, often without visible alerts to the user.


![infection-chain.jpeg](https://sb-cms.s3.ap-south-1.amazonaws.com/infection_chain_d9550a894c.jpeg)
***New WarmCookie Infection Chain (source: Gen Threat Labs)***

During installation, WarmCookie performs anti-VM checks to verify that it is running on a real machine rather than in a sandboxed or virtual environment. Once confirmed, it transmits a detailed fingerprint of the system to the command-and-control (C2) server, awaiting further commands. The process is seamless, and victims are typically unaware of the compromise.

### Strategic Use of FakeUpdate Campaigns in France

This particular campaign by SocGolish primarily targets French users, exploiting trust in familiar brands like Chrome and Java. 

Domains such as _"edgeupdate[.]com"_ and _"mozilaupgrade[.]com"_ have been utilized to replicate the visual elements of genuine updates, adding credibility to the prompts and making detection challenging for everyday users.

### Defensive Measures and Best Practices

Given the sophistication of WarmCookie and the deceptive nature of FakeUpdate campaigns, vigilance is essential. 
Users should be reminded that:

Modern browsers update in the background, requiring only a restart in most cases. Manual updates should be verified directly through the official website of each software provider.

Fake update prompts can appear on seemingly trustworthy websites due to compromised content, so skepticism is warranted, even on familiar sites.


In this campaign, SocGolish’s calculated methods—targeting unsuspecting users with legitimate-seeming prompts and leveraging WarmCookie’s capabilities—reveal an elevated level of technical and psychological strategy. 

Staying updated on the latest developments in malware campaigns like FakeUpdate is crucial for users and organizations alike, as WarmCookie’s expanding abilities demonstrate a clear trajectory toward even more targeted and persistent attacks in the future.

New WarmCookie Backdoor Hides in Fake Updates Across France

A security vulnerability was discovered in the [AWS](https://www.secureblink.com/cyber-security-news/15-000-aws-load-balancers-at-risk-secure-your-apps-from-al-beast-vulnerability-now) Cloud Development Kit (CDK), an open-source framework that allows developers to define cloud infrastructure using familiar programming languages. 

This vulnerability could, under specific circumstances, enable an attacker to gain administrative access to a target AWS account, leading to a full account takeover. 

This [Threatfeed](https://www.secureblink.com/cyber-security-news) delves into the nature of the vulnerability, the conditions under which it can be exploited, and the steps taken to mitigate the risk.

### AWS CDK and Infrastructure as Code

Infrastructure as Code (IaC) revolutionizes the way computing infrastructure is managed and provisioned by utilizing code instead of manual configurations. It allows developers to define essential infrastructure components—such as servers, databases, and networks—through machine-readable files.

The AWS Cloud Development Kit (CDK) is a framework that enables developers to define cloud infrastructure using familiar programming languages like [Python](https://www.secureblink.com/cyber-security-news/python-repo-hit-by-phony-dmca-takedown-restored-by-git-hub), TypeScript, or [JavaScript](https://www.secureblink.com/cyber-security-news/50-k-users-from-40-banks-globally-targeted-by-new-java-script-malware). 
CDK translates this code into AWS CloudFormation templates, which AWS can interpret and deploy efficiently. 

This approach streamlines the process of building and managing cloud infrastructure, allowing developers to write, customize, and deploy cloud resources directly from their codebase.


---

### Understanding the CDK Bootstrap Process

Before deploying applications using AWS CDK, users must bootstrap their environment using the cdk bootstrap command. This process deploys a CloudFormation template that automatically creates essential infrastructure components, including:

[IAM Roles](https://docs.aws.amazon.com/cdk/v2/guide/bootstrapping-env.html#bootstrapping-env-default) and Policies: Roles like FilePublishingRole and CloudFormationExecutionRole are created. The FilePublishingRole allows CDK to interact with the bootstrapped S3 bucket for uploading and deleting assets. 
The CloudFormationExecutionRole grants CloudFormation permission to perform stack deployments on the user's behalf, typically with administrative privileges by default.

A staging S3 bucket is created to store deployment assets, such as CloudFormation templates and other resources. These assets are first generated and saved locally in the cdk.out directory before being uploaded to the S3 staging bucket for use during the deployment process.


### Naming Conventions

The resources created during the bootstrap process follow a predictable naming pattern:

`cdk-{Qualifier}-{Description}-{Account-ID}-{Region}`

A unique, nine-character string value. By default, this is hnb659fds, but users can customize it.

A short descriptor of the resource (e.g., cfn-exec-role for CloudFormationExecutionRole).

Account-ID: The AWS account ID.

Region: The AWS Region where the CDK is deployed.


For example, the CloudFormationExecutionRole might be named:

`cdk-hnb659fds-cfn-exec-role-123456789012-us-east-1`


---

### Exploiting Missing S3 Buckets

#### Predictable Bucket Names and Shadow Resources

The staging S3 bucket's name is predictable, especially when users use the default qualifier. It follows the pattern:

`cdk-{Qualifier}-assets-{Account-ID}-{Region}`

Given that many users do not [customize the qualifier](https://docs.aws.amazon.com/cdk/v2/guide/bootstrapping-troubleshoot.html), using the default hnb659fds, attackers can predict the bucket name if they know the AWS Account ID and the Region.

#### S3 Bucket Namesquatting

Since S3 bucket names are globally unique, an attacker can perform _"S3 Bucket Namesquatting"_ or _"Bucket Sniping"_ by creating a bucket with the predicted name if it doesn't already exist. This situation can occur in two scenarios:

1. **New CDK Users:** If a user has not yet bootstrapped their CDK environment, an attacker can preemptively create the staging bucket. When the user attempts to bootstrap, the process fails due to the bucket's existence, causing a partial denial-of-service (DoS). The user can resolve this by using a custom qualifier.


2. **Deleted Staging Buckets:** If a user previously bootstrapped CDK but later manually deleted the staging S3 bucket—perhaps to free up resources—the bucket name becomes available. An attacker can then claim this bucket.



### Implications of the Attack

When the user performs a cdk deploy, the CDK uses existing roles and resources, including the CloudFormationExecutionRole with administrative privileges. 
If the staging bucket is under the attacker's control:

The CDK uploads deployment assets, including CloudFormation templates, to the attacker's bucket.

The attacker can intercept and modify the templates, injecting malicious code or resources.

CloudFormation, using its administrative role, deploys these tampered templates in the victim's account.

The attacker can create an admin role within the victim's account, which they can assume to gain full administrative access.



---

### Attack Workflow and Potential Impact

#### Pre-Attack Setup by the Attacker

1.The attacker creates the staging S3 bucket with the predictable name corresponding to the victim's account and region.


2.The attacker sets permissive policies on the bucket to allow public access and interaction.


3.A Lambda function is configured to trigger on PutObject events, designed to inject malicious resources into any uploaded CloudFormation template.



### Attack Execution Steps

1. User Deploys CDK Application: The victim runs cdk deploy, unaware that the staging bucket is controlled by the attacker.


2. Asset Upload: The CDK uploads the CloudFormation template to the attacker's bucket.


3. Template Tampering: The attacker's Lambda function modifies the template, injecting a new admin role or other malicious resources.


4. Deployment of Malicious Template: CloudFormation in the victim's account retrieves and deploys the tampered template, using the CloudFormationExecutionRole with administrative privileges.


5. Attacker Gains Access: The newly created admin role allows the attacker to assume administrative access to the victim's [AWS](https://docs.aws.amazon.com/cdk/v2/guide/bootstrapping.html) account.



### Severity of the Impact

This vulnerability enables a complete compromise of the victim's AWS account, granting the attacker the ability to:

- Access and manipulate resources.

- Exfiltrate sensitive data.

- Launch further attacks or exploitations.



---

### Statistical Analysis of Affected Users

To assess the prevalence of this vulnerability, a study was conducted:

Dataset: A list of 38,560 well-known AWS Account IDs.

Regions Scanned: us-east-1, us-west-2, and eu-west-1.

#### Methodology:

Checked for the existence of the CloudFormationExecutionRole to confirm CDK usage.

Verified whether the corresponding staging S3 bucket existed.


#### Findings:

CDK Usage: 782 accounts (2%) had CDK roles, indicating CDK usage.

Vulnerable Accounts: 81 accounts (10% of CDK users) lacked the staging S3 bucket, making them susceptible to the attack.


AWS Confirmation: AWS corroborated that approximately 1% of [CDK](https://docs.aws.amazon.com/cdk/v2/guide/home.html) users were impacted.



---

### Mitigation Strategies

#### AWS's Response

Following the disclosure, AWS implemented several fixes:

In CDK version [v2.149.0](https://github.com/aws/aws-cdk/releases/tag/v2.149.0), a condition was added to the FilePublishingRole to ensure it only trusts S3 buckets within the user's account.


AWS [emphasized](https://github.com/search?q=/cdk-hnb659fds-(.+-)%257B1,5%257D%255Cd/&type=code) the importance of customizing bootstrapping resources and using a custom qualifier.


Direct communication with potentially affected customers.

CLI terminal messages prompting users to upgrade bootstrap resources.




### Required User Actions

Despite AWS's fixes, user intervention is necessary:

Upgrade CDK:

Update to CDK version v2.149.0 or later.

Re-run the cdk bootstrap command to apply the new configurations.


#### Manual Role Adjustment:

If upgrading is not immediate, modify the FilePublishingRole IAM policy.

Add a condition to restrict the role to trust only [S3 buckets](https://onecloudplease.com/blog/s3-bucket-namesquatting) within the user's account.




---

### Recommendations and Best Practices

To safeguard against similar vulnerabilities, users should adopt the following practices:

1. Treat AWS Account IDs as Sensitive:

Avoid sharing AWS Account IDs publicly.

Recognize that knowledge of an account ID can facilitate targeted attacks.



2. Customize Bootstrapping Qualifier:

Always specify a custom --qualifier when running cdk bootstrap.

This reduces the predictability of resource names.



3. Implement IAM Policy Conditions:

Use conditions like aws:ResourceAccount in IAM policies to restrict access based on the bucket owner's AWS account ID.

Ensure that roles and policies are scoped appropriately to prevent unauthorized access.



4. Avoid Predictable Resource Names:

Incorporate unique identifiers or hashes into resource names, especially for globally unique services like S3.

This prevents attackers from predicting and preemptively claiming resource names.



5. Regularly Audit and Monitor Resources:

Periodically check for missing or inadvertently deleted resources critical for deployment processes.

Monitor logs and alerts for unusual activities during deployment.

Critical FortiManager Vulnerability Exploited in Zero-Day Attacks

Recent investigations have revealed two separate but related attacks targeting the Ethereum developer community through malicious npm packages. 

These attacks involve typosquatting popular Ethereum libraries and inserting malicious code to exfiltrate private keys and compromise developer systems. 

Understanding these incidents is crucial for safeguarding projects and personal security in the blockchain ecosystem.

### First Attack: Trojanized Ethers Forks Attempting to Steal Private Keys

A series of malicious packages were [published](https://blog.phylum.io/trojanized-ethers-forks-on-npm-attempting-to-steal-ethereum-private-keys/) on npm impersonating the widely used [ethers library](https://www.npmjs.com/package/ethers), which facilitates interaction with the Ethereum blockchain and has over 1.3 million weekly downloads. 

The attacker created packages with names similar to the legitimate library:

- `[ethers-mew](https://npm-stat.com/charts.html?package=ethers-mew)`
- `[ethers-web3](https://npm-stat.com/charts.html?package=ethers-web3)`
- `[ethers-6](https://npm-stat.com/charts.html?package=ethers-6)`
- `[ethers-eth](https://npm-stat.com/charts.html?package=ethers-eth)`
- `[ethers-aaa](https://npm-stat.com/charts.html?package=ethers-aaa)`
- `[ethers-audit](https://npm-stat.com/charts.html?package=ethers-audit)`
- `[ethers-test](https://npm-stat.com/charts.html?package=ethers-test)`

These packages contain malicious code designed to:

- **1. Exfiltrate Ethereum Private Keys:** When a developer instantiated a new Wallet using the malicious library, the code would send the private key to a remote server controlled by the attacker (https://ether-sign.com/api/checkServer).


- **2. Gain Unauthorized SSH Access:** The malware attempted to append the attacker's SSH public key to the root user's authorized_keys file, potentially granting the attacker remote SSH access to the developer's machine.

### Technical Details

- **Wallet Constructor Modification:** The Wallet class in the malicious package includes additional code that calls a function checkAddress with the private key as an argument.

- **Layered Indirection:** The checkAddress function calls another function checkServer, which makes an HTTP POST request to the attacker's server, sending the private key.

- **SSH Key Insertion:** A function named superSignKey writes the attacker's SSH public key to the root user's authorized_keys file.

- **Obfuscation Tactics:** The attacker uses plausible function names and mimics the structure of the legitimate ethers library to avoid detection. The malicious code is spread across multiple files and modules, making it harder to trace.

### Indicators of Compromise (IOCs)

- **Malicious Domain:** ether-sign.com (Registered on October 15, 2023)

- **IP Address:** 88.99.95.50 (Hosted on Hetzner Online)

- **Attacker's SSH Public Key:** An SSH key associated with the username cp@DESKTOP-7BQLEIP is inserted into the authorized_keys file.

### Second Attack: Typosquat of Ethereum-Cryptography Package Sending Private Keys to Remote Server

An earlier attack involved typosquatting the widely-used ethereum-cryptography package, which has over 1.2 million downloads and contains cryptographic primitives essential for Ethereum development.

The attacker published malicious packages with names similar to the legitimate package:

- `ethereum-cryptographyy (note the extra 'y')`

- `ethereum-cryptographyyy`

Additionally, the attacker created a malicious version of a critical dependency:
@jackshanyeshuzi/curvess (typosquat of @noble/curves)

### Malicious Activities

- **1. Exfiltration of Private Keys:** The attacker modified the cryptographic functions to send private keys to a server located in China (wallet.cba123.cn).


- **2. Maintaining Core Functionality:** The malicious packages retained all the legitimate functionalities to avoid raising suspicion, with the only addition being the code that exfiltrates the private key.


- **3. Attempted Obfuscation:** In later versions, the attacker attempted to obfuscate the malicious code, although the obfuscation was relatively amateurish and could still be deciphered upon close inspection.

### Technical Details

- **Modified Dependencies:** The attacker changed the package's dependencies to point to the malicious @jackshanyeshuzi/curvess instead of the legitimate @noble/curves.

- **Insertion of Malicious Code:** Within the cryptographic functions, specifically in files like weierstrass.js, the attacker inserted code that sends the user's private key to the remote server.

- **Server Location:** The domain wallet.cba123.cn is registered in China, and WHOIS records confirm its location.

### Indicators of Compromise (IOCs)

Malicious Domain: wallet.cba123.cn

Affected Packages and Versions: Multiple versions of `ethereum-cryptographyyy` and @jackshanyeshuzi/curvess were published over a short period.


### Timeline of Malicious Activity

- **August 3, 2023:** Initial publication of @jackshanyeshuzi/curvess and ethereum-cryptographyy.

- **August 4, 2023:** Multiple updates and additional malicious packages published.

The attacker unpublished some packages shortly after publishing them, possibly to avoid detection.



---

### Comparative Analysis

#### Attack Vectors

Both attacks leveraged typosquatting, creating packages with names similar to popular libraries to deceive developers into installing them.

The attackers exploited the trust developers place in widely-used open-source packages, especially those related to cryptography.


#### Malicious Payloads

- **Private Key Exfiltration:** The primary goal in both attacks was to steal Ethereum private keys, which could lead to immediate financial loss and compromise of blockchain assets.

- **System Compromise:** The first attack also attempted to gain SSH access to the developer's machine, potentially allowing the attacker to execute arbitrary commands and access sensitive data.


### Obfuscation Techniques

Both attackers attempted to hide their malicious code within legitimate-looking functions and modules.

They used plausible function names and maintained the overall structure of the original libraries to avoid detection during casual code reviews.


#### Differences

The first attack was more aggressive in attempting to gain system-level access through SSH key insertion.

The second attack focused solely on exfiltrating private keys and tried to maintain a low profile by keeping the malicious code changes minimal.




### Recommendations

#### 1. Vigilance in Dependency Management

- **Verify Package Names:** Pay close attention to package names to avoid typosquatting traps. Even a single character difference can indicate a malicious package.

- **Check Package Metadata:** Review the number of downloads, version history, and publisher information. New packages with low download counts and recent publication dates should be treated with caution.


#### 2. Use Trusted Sources

- **Official Repositories:** Whenever possible, use packages from verified publishers or official repositories.

- **Package Signing:** Consider using packages that are signed or verified through checksum to ensure integrity.


#### 3. Code Review

- **Inspect Dependencies:** Before adding new dependencies, especially those handling sensitive operations like cryptography, review the source code if feasible.

- **Automated Scanning Tools:** Utilize security tools that can automatically scan dependencies for known vulnerabilities or malicious code patterns.


#### 4. Network Monitoring

- **Monitor Outgoing Traffic:** Use network monitoring solutions to detect and block unauthorized outbound requests to unknown domains.

- **Alert on Suspicious Activity:** Set up alerts for unusual network activities, such as HTTP requests to domains not associated with your development work.


#### 5. System Security Practices

- **Regular Audits:** Periodically audit system files like authorized_keys to detect unauthorized modifications.

- **Least Privilege Principle:** Avoid running development tools and applications with root or administrator privileges unless necessary.

- **Update and Patch:** Keep your systems and applications updated to protect against known vulnerabilities.


#### 6. Community Awareness

- **Report Suspicious Packages:** If you discover a malicious package, report it to the package registry and the wider community.

- **Stay Informed:** Keep abreast of security advisories and reports from reputable sources within the developer community.

Malicious npm Packages Steal Ethereum Keys and Gain SSH Access

The [Internet Archive](https://www.secureblink.com/cyber-security-news/internet-archive-hacked-31-million-users-exposed), a cornerstone of digital preservation, has experienced another significant data breach. This time, the breach occurred through their Zendesk email support platform after threat actors exploited exposed [GitLab](https://www.secureblink.com/cyber-security-news/gitlab-addressed-a-critical-ssrf-flaw-discovered-to-expose-the-orgs'-internal-servers) authentication tokens. 

Despite prior warnings, the organization failed to rotate these tokens adequately, leading to unauthorized access to sensitive data.

### Background of the Internet Archive Breach

Beginning last night, numerous individuals reported receiving unexpected emails in response to old [support tickets](https://developer.zendesk.com/api-reference/ticketing/tickets/ticket-attachments/#show-attachment) submitted to the Internet Archive. These emails, originating from the organization's official Zendesk server, alerted users to the breach:

>>> _"It's dispiriting to see that even after being made aware of the breach weeks ago, IA has still not done the due diligence of rotating many of the API keys that were exposed in their gitlab secrets. As demonstrated by this message, this includes a Zendesk token with perms to access 800K+ support tickets sent to info@archive.org since 2018."_

The threat actor emphasized the magnitude of the breach, highlighting access to over 800,000 support tickets submitted since 2018. The authenticity of these emails was verified through email headers that passed all DKIM, DMARC, and SPF authentication checks, confirming they were sent from an authorized Zendesk server.

### Exposure of Personal Identifiable Information (PII)

Compounding the severity of the breach, some users had previously uploaded personal identification documents when requesting the removal of content from the Wayback Machine. Depending on the level of access the threat actor had within Zendesk, these sensitive attachments might now be compromised.

![zendesk-emails.jpg](https://sb-cms.s3.ap-south-1.amazonaws.com/zendesk_emails_7a398d2ed5.jpg)
***Email snapshot sent by threat actor to Internet Archive Zendesk (Source: BleepingComputer)***

The Zendesk Attachments API allows users to upload files to support tickets, which are then accessible through links in the agent interface and notification emails. 
Attachments are represented as JSON objects containing details like file_name, content_type, and content_url. If the threat actor exploited this API, they could have downloaded personal documents submitted by users.

### Timeline and Failure to Act

BleepingComputer attempted repetatively to [warn](https://www.bleepingcomputer.com/news/security/internet-archive-breached-again-through-stolen-access-tokens/) the Internet Archive about the exposed GitLab authentication tokens. On October 9th, they reported that the Internet Archive suffered two simultaneous attacks:

- 1. A data breach compromising user data for 33 million users.
- 2. A DDoS attack orchestrated by a pro-Palestinian group named SN_BlackMeta.
While these attacks transpired concurrently, they were perpetrated by different threat actors. Misreporting led many to incorrectly attribute the data breach to SN_BlackMeta, frustrating the actual hacker who then reached out to Secure Blink to claim responsibility and provide details.

![js-alert.jpg](https://sb-cms.s3.ap-south-1.amazonaws.com/js_alert_70e8ef5478.jpg)
***Data Breach Notification on Internet Archive JavaScript Alert (Source: BleepingComputer)***

### Mechanism of the Breach
The initial point of compromise was an exposed GitLab configuration file on one of the Internet Archive's development servers (services-hls.dev.archive.org). 
This file contained an authentication token that had been exposed since at least December 2022. The threat actor used this token to download the Internet Archive's source code.

![gitlab-token.jpg](https://sb-cms.s3.ap-south-1.amazonaws.com/gitlab_token_9b779b3389.jpg)
***Internet Archive Exposed GitLab Authentication Token (Source: BleepingComputer)***

Within the source code, additional credentials and authentication tokens were discovered, including those for the organization's database management system. This access allowed the hacker to:

### Download the user database.

#### Access further source code.

**Modify the website.**
The threat actor claims to have exfiltrated 7TB of data, though no samples were provided for verification. The inclusion of API access tokens for the Internet Archive's Zendesk support system in the stolen data further exacerbated the situation.

**Negligence in Security Practices**

Despite multiple warnings from Secure Blink, the Internet Archive failed to rotate the compromised authentication tokens promptly. The threat actor highlighted this negligence in their communication:

>> _"Whether you were trying to ask a general question, or requesting the removal of your site from the Wayback Machine, your data is now in the hands of some random guy. If not me, it'd be someone else."_



This statement attempts to underscores the critical importance of proactive security measures and timely responses to potential threats.

### Understanding the Zendesk Attachments API Vulnerability

The Zendesk Attachments API is designed to facilitate the uploading and attaching of files to support ticket comments. Key functionalities include:

- **Uploading Files:** Users can upload files and attach them to ticket comments.

- **Attachment Accessibility:** Attachments appear as links in the agent interface and notification emails.

- **Attachment Properties:** Attachments are represented as JSON objects with properties such as content_type, content_url, file_name, size, etc.


Given the potential sensitivity of the uploaded files (e.g., personal IDs), unauthorized access to these attachments poses a significant privacy risk. The API documentation specifies that while files are visible to any authenticated user until the upload token is consumed, once associated with a ticket, visibility is restricted. However, in this breach, the threat actor's access to the Zendesk platform could bypass these restrictions.

### Implications for Users and Organizations

The breach has several profound implications:

- **User Data Exposure:** Personal data, including identification documents, may have been compromised.

- **Trust Erosion:** Users may lose confidence in the Internet Archive's ability to safeguard their information.

- **Regulatory Scrutiny:** Potential violations of data protection regulations could lead to legal repercussions.


### Recommendations and Preventative Measures

#### For Users:

- **Monitor Accounts:** Keep an eye on personal accounts for any suspicious activity.

- **Change Passwords:** Update passwords for accounts associated with the Internet Archive.

- **Identity Protection:** Consider credit monitoring services if personal IDs were uploaded.


#### For the Internet Archive and Similar Organizations:

- **Rotate Credentials Regularly:** Implement policies for regular rotation of authentication tokens and API keys.

- **Audit and Monitor:** Conduct frequent security audits to identify and remediate vulnerabilities.

- **Implement Least Privilege Access:** Limit access permissions to only what is necessary for each role.

- **Enhance Incident Response:** Develop robust incident response plans to address breaches swiftly.


The Internet Archive's data breach is not just a stark reminder of the vulnerabilities that can arise from lapses in security protocols. In an era where data is a critical commodity, both organizations and users must remain super weary. 
Proactive security measures, timely response to threats, and user education are critical components in safeguarding against such breaches.

Internet Archive Faces Another Breach Due to Exposed GitLab Auth Tokens

Hackers have breached Comsecure, ESET's exclusive partner in Israel, to conduct a sophisticated phishing campaign targeting Israeli businesses. 

The attackers utilized legitimate ESET infrastructure to distribute data wiper malware disguised as antivirus software, aiming for destructive attacks on Israeli organizations.

### What Happened?

#### Compromise of ESET Israel's Partner

On October 8th, a phishing campaign was launched where emails branded with ESET's logo were sent from the legitimate domain eset.co.il. 

This indicates that the email servers of ESET's Israeli distributor, Comsecure, were compromised.

#### Phishing Emails Sent from Legitimate Servers

The phishing emails appeared authentic as they passed SPF, DKIM, and DMARC authentication checks. This means that the emails originated from verified ESET servers, making them highly convincing to recipients and difficult for security systems to detect.

### Phishing Campaign Details

#### Disguised as ESET's Advanced Threat Defense Team

The emails pretended to be from _"ESET's Advanced Threat Defense Team,"_ warning recipients about state-backed attackers targeting their devices. The message leveraged fear of sophisticated threats to prompt immediate action.

### Introduction of "ESET Unleashed"

To counter the alleged threat, the email offered a download link to _"ESET Unleashed,"_ purportedly a more advanced antivirus tool. The download link was hosted on the legitimate eset.co.il domain, adding further credibility.

#### Malicious Payload

Contents of the Downloaded ZIP File

The ZIP archive contained:

Four legitimate ESET DLL files digitally signed by ESET's code-signing certificate.

An unsigned Setup.exe file, which was the malicious data wiper.

ESET Israel Partner HACKED to Deploy Data Wipers in Phishing Attacks

A newly identified [Linux](https://www.secureblink.com/cyber-security-news/new-regre-ss-hion-critical-open-ssh-vulnerability-allows-root-access-on-linux) variant of the notorious FASTCash malware has been discovered, expanding the attack surface of North Korean hackers targeting financial institutions. 

Previously known to compromise IBM AIX and Microsoft Windows systems, this malware now poses a threat to Linux-based payment switch servers, enabling unauthorized cash withdrawals from ATMs. 

This development underscores the evolving tactics of threat actors like Hidden Cobra (also known as APT38 or [Lazarus Group](https://www.secureblink.com/cyber-security-news/lazarus-targets-spanish-aerospace-with-lightless-can)) and highlights the urgent need for robust security measures in the financial sector.

### Background

#### Evolution of FASTCash Malware

The term FASTCash refers to a malware family [attributed](https://doubleagent.net/fastcash-for-linux/) to North Korean hackers, designed to infiltrate payment switch systems within compromised networks. Since at least 2016, FASTCash has facilitated unauthorized ATM cash-outs by manipulating transaction messages, resulting in the theft of tens of millions of dollars per incident across multiple countries.

**2018:** The U.S. Cybersecurity and Infrastructure Security Agency (CISA) [first warned](https://www.cisa.gov/news-events/alerts/2018/10/02/hidden-cobra-fastcash-campaign) about FASTCash, linking it to Hidden Cobra.

**2019:** The first Windows variant surfaced, expanding the malware's reach beyond IBM AIX systems.

**2020:** CISA updated its advisory to include the Windows variant, noting significant developments in the malware's capabilities.

**2021:** Indictments were announced for three North Koreans involved in these schemes, responsible for over $1.3 billion in theft.


### Technical Analysis of the Linux Variant

#### Compilation & Deployment

The newly discovered Linux variant was compiled for Ubuntu Linux 20.04 using GCC 11.3.0. Analysis suggests that the malware was developed after April 21, 2022, likely within a [VMware](https://www.secureblink.com/cyber-security-news/patch-critical-v-mware-v-center-vulnerabilities-to-prevent-rce-now) virtual machine environment. 

The use of Ubuntu indicates a shift, as traditional payment switch systems often run on proprietary UNIX systems or Windows.

#### Similarities to Previous Variants

The Linux variant shares operational similarities with its Windows and AIX predecessors:

Currency Manipulation: Both the Linux and Windows variants operate in Turkish Lira (TRY), while the AIX variant used Indian Rupee (INR).

ISO8583 Message Manipulation: The malware intercepts and manipulates ISO8583 messages, the standard for financial transaction card-originated messages.

Approval of Declined Transactions: It authorizes previously declined transactions by injecting fraudulent response messages before they reach the acquirer.


### Intercepting Transaction Messages

#### Payment Switch Systems

Payment switches act as intermediaries, routing transaction messages between ATMs/POS terminals and financial institutions. By compromising these systems, the malware can manipulate transaction data undetected.

#### ISO8583 Protocol Exploitation

The malware hooks into the recv function of network processes to intercept ISO8583 messages, specifically targeting:

Message Type Indicators (MTIs): Focuses on authorization requests (1xx) and financial transactions (2xx).

Data Elements (DEs): Manipulates fields such as DE2 (Primary Account Number), DE3 (Processing Code), DE4 (Transaction Amount), DE49 (Transaction Currency Code), and DE54 (Additional Amounts).


![diagram.jpg](https://sb-cms.s3.ap-south-1.amazonaws.com/diagram_5d10d93578.jpg)
***FASTCash Operational Flow (Source:doubleagent.net)***

### Process Injection Techniques

Using the ptrace system call, the malware injects itself into running processes on the payment switch server. It employs shared libraries (libMyFc.so) to hook network functions, allowing it to monitor and alter transaction messages in real-time.

### Fraudulent Transaction Approval

Upon intercepting a declined transaction due to insufficient funds (Processing Code 51), the malware:

1. Generates a Random Amount: Between 12,000 and 30,000 TRY (~$350 to $875).


2. Modifies Response Codes: Sets DE38 (Approval Code) and DE39 (Action Code) to indicate approval.


3. Adjusts Data Elements: Removes specific DEs related to security and authentication to avoid detection.


4. Sends Manipulated Response: Forwards the fraudulent approval to the bank's central systems, enabling unauthorized cash withdrawals.



### Indicators of Compromise (IoCs)

The following SHA-256 hashes are associated with the Linux variant:

f34b532117b3431387f11e3d92dc9ff417ec5dcee38a0175d39e323e5fdb1d2c

7f3d046b2c5d8c008164408a24cac7e820467ff0dd9764e1d6ac4e70623a1071 (UPX packed)


### Impact and Implications

#### Expanded Attack Surface

The discovery of a Linux variant indicates that North Korean hackers are broadening their targets to include a wider range of operating systems. This expansion poses significant risks to financial institutions that may rely on Linux-based systems for payment processing.

#### Financial and Reputational Damage

Unauthorized cash withdrawals facilitated by FASTCash can lead to substantial financial losses and damage the reputation of affected institutions. The malware's ability to evade detection exacerbates these risks.

#### Challenges in Detection

As of its discovery, the Linux variant had zero detections on VirusTotal, highlighting the difficulty traditional security tools face in identifying such threats.

### Detection and Prevention

#### Implementing Robust Security Measures

Financial institutions should adhere to CISA's recommendations:

**Message Authentication Codes:** Require and verify MACs on issuer financial request and response messages.

**Chip and PIN Requirements:** Implement chip and PIN authentication for debit and credit cards.

**Cryptogram Validation:** Perform authorization response cryptogram validation for chip and PIN transactions.

Newly Discovered Linux Variant of FASTCash Malware Targets ATMs

Cisco is found to be currently investigating a possible data breach following reports that allegedly stolen data has surfaced for sale on a hacking forum. 

The stolen data claims have been linked to a threat actor known as "IntelBroker" who, along with two others— "EnergyWeaponUser" and "zjj"—claims to have breached Cisco on June 10, 2024. 

According to IntelBroker, the breach compromised a whole host of sensitive information, including:

- GitHub and GitLab project repositories
- Source code
- Hard-coded credentials
- SSL Certificates
- Docker builds
- API tokens
- AWS and Azure storage bucket data
- Confidential Cisco documents, and more.

## Cisco’s Response

A Cisco spokesperson confirmed the company is aware of the alleged breach and that an investigation is ongoing to assess the extent of the situation. At this time, Cisco has not confirmed the authenticity of the claims or the data samples that have been leaked.

**Cisco's statement:**
> _"We have launched an investigation to assess this claim, and our investigation is ongoing."_

## Alleged Attacker’s Claims

IntelBroker which has been involved in many targeted cyberattacks namely [Facebook](https://www.secureblink.com/cyber-security-news/200-000-facebook-marketplace-records-leaked-claims-intel-broker) & [General Electronics](https://www.secureblink.com/cyber-security-news/intel-broker-offers-ge-s-pipelines-for-500-amid-cyberattack-probe) along with their associates have provided samples of the alleged stolen data on a hacking forum. These samples include:

- A customer database
- Customer information
- Documentation related to customers
- Screenshots from internal customer management portals.

While details of how the data breach has transpired remain still unclear, the type of data presented suggests access to core developer infrastructure and proprietary code repositories, potentially via compromised DevOps systems. 

### Critical Data at Risk

The threat actor’s post indicated that many of Cisco’s most crucial assets were allegedly infiltrated. 

Some of the more alarming categories include:

1. **Source Code Repositories**: IntelBroker claims access to multiple source code repositories hosted on GitHub, GitLab, and SonarQube. This can pose a serious risk to Cisco’s intellectual property, potentially allowing attackers to identify vulnerabilities in Cisco products.
   
2. **Hard-Coded Credentials and API Tokens**: The presence of hard-coded credentials within the code repositories could allow further exploitation of other systems if not remediated promptly. 

3. **Confidential Cisco Documents**: Exposure of internal documentation could reveal sensitive corporate strategies, undisclosed technologies, and private communications.

4. **Cloud Infrastructure Access**: AWS private buckets, Azure storage, and Docker build data are all listed as compromised. Breaching cloud infrastructure is a serious issue as it can lead to further compromise of confidential services or data leakage.

5. **Private & Public Keys, SSL Certificates**: If SSL certificates or cryptographic keys have been compromised, the breach could extend to disrupting secure communication channels.

## Analysis of Previous Incidents

This is not the first time IntelBroker has been associated with major data breaches. Since June 2024, the group has been involved in leaking or selling data from various high-profile companies such as [T-Mobile](https://www.secureblink.com/cyber-security-news/second-t-mobile-data-breach-of-2023-attackers-access-info-of-hundreds), [AMD](https://www.secureblink.com/cyber-security-news/sink-close-a-high-severity-amd-cpu-vulnerability-enables-undetectable-malware), and [Apple](https://www.secureblink.com/cyber-security-news/apple-urgently-releases-i-os-update-to-fix-voice-over-password-flaw). 
These previous attacks reportedly exploited vulnerabilities in third-party DevOps and software development services providers. 

It remains unclear whether the Cisco breach is related to those earlier incidents, but the scope of the alleged data exfiltration suggests that a third-party service provider might have been targeted once again.

However, this isn't an isolated intrusion where Cisco has been involved, previously the company suffered many intrusions such as detection of backdoor vulnerability in there [smart licensing utility](https://www.secureblink.com/cyber-security-news/cisco-patches-critical-backdoor-vulnerability-in-smart-licensing-utility-1), there [VPN have been exploited](https://www.secureblink.com/cyber-security-news/ransomware-group-exploit-cisco-vpn-zero-day-vulnerability) by ransomware group, their [CISCO SPA 112 Phone Adapters](https://www.secureblink.com/cyber-security-news/cisco-spa-112-phone-adapters-vulnerable-to-arbitrary-code-execution) were vulnerable to arbitrary code execution, [Cisco AnyConnect](https://www.secureblink.com/cyber-security-news/any-connect-security-flaw-being-exploited-in-the-wild-cisco-warned) had been exploited in the wild and many more.


Third-party vendors in DevOps often possess extensive access to company infrastructure, making them a high-value target for cybercriminals.

## Implications of the Cisco Data Breach

If IntelBroker’s claims prove to be accurate, this breach could have severe implications for Cisco’s customers and partners. Compromised source code, credentials, and API tokens could potentially lead to:

1. **Intellectual Property Theft**: With source code and product designs in hand, competitors or criminal groups could clone or exploit Cisco products.

2. **Secondary Attacks**: The use of compromised credentials, API tokens, or customer documentation could lead to follow-up attacks, including ransomware, phishing, or fraud targeting Cisco’s customers.

3. **Loss of Trust**: A breach of this magnitude could significantly damage Cisco's reputation, especially among enterprise clients who rely on its technologies for secure networking solutions.

4. **Regulatory and Legal Consequences**: Cisco could face significant regulatory scrutiny, especially if customer or proprietary data is found to have been insufficiently protected.

### Potential Remediation Strategies

While Cisco continues its investigation, there are several immediate steps the company should consider:

- **Revocation of Exposed Certificates and Credentials**: Any SSL certificates, private keys, or hard-coded credentials that were potentially compromised must be revoked and replaced immediately.
  
- **Patch and Secure DevOps Systems**: Since DevOps infrastructure appears to be the common thread in IntelBroker’s past breaches, Cisco should audit and strengthen security controls around its own DevOps tools and those of any third-party vendors.

- **Customer Communication and Incident Response**: If customer information is indeed part of the compromised data, Cisco will need to proactively inform affected customers and assist them in securing their systems.

- **Security Audit of Code Repositories**: A thorough audit of all GitHub, GitLab, and SonarQube repositories should be conducted to identify any potential vulnerabilities or further exposures of sensitive information.


As more companies integrate third-party services into their core development workflows, they become increasingly vulnerable to attacks targeting those services. 

In the short term, it is critical for Cisco to validate IntelBroker’s claims, secure any exposed infrastructure, and collaborate with affected customers to mitigate potential risks. The long-term challenge will be fortifying the security of its development pipelines to prevent similar breaches in the future.




Cisco is found to be currently investigating a possible data breach following reports that allegedly stolen data has surfaced for sale on a hacking forum.

On Wednesday afternoon, visitors to archive.org were met with an unexpected and unsettling JavaScript alert:

> _"Have you ever felt like the Internet Archive runs on sticks and is constantly on the verge of suffering a catastrophic security breach? It just happened. See 31 million of you on HIBP!"_



The message was a stark announcement from the hackers themselves, indicating not only the breach but also hinting at the data's impending addition to Have I Been Pwned (HIBP), a renowned data breach notification service.

### Confirmation from Have I Been Pwned

Troy Hunt, the creator of HIBP, confirmed that he received a file nine days prior containing the stolen data:

File Name: `ia_users.sql`

Size: `6.4GB SQL file`

Contents: `Email addresses, screen names, password change timestamps, bcrypt-hashed passwords, and other internal data`.

Unique Email Addresses: `31 million`


Hunt verified the data's authenticity by matching it with known user accounts, including that of cybersecurity researcher Scott Helme. Helme confirmed that the bcrypt-hashed password in the database matched his own records.

### Internet Archive's Response

Later that evening, Brewster Kahle, founder of the Internet Archive, acknowledged the breach on X (formerly Twitter):

> _"What we know: DDoS attack—fended off for now; defacement of our website via JS library; breach of usernames/email/salted-encrypted passwords. What we've done: Disabled the JS library, scrubbing systems, upgrading security. Will share more as we know it."_



In addition to the data breach, the Internet Archive suffered a Distributed Denial of Service (DDoS) attack, causing significant downtime and accessibility issues for users worldwide.

### Attackers: BlackMeta Hacktivist Group

An account on X named SN_Blackmeta claimed responsibility for the attack. The group has a history of targeting the Internet Archive, with previous DDoS attacks reported in May. They indicated plans for additional attacks, stating they act "just because they can," without any explicit demands or statements.

### Timeline of Events

September 28th, 2024: Most recent timestamp in the stolen data, likely when the database was compromised.

October 6th, 2024: Troy Hunt contacts the Internet Archive, initiating a disclosure process.

Internet Archive's Wayback Machine suffers a catastrophic breach; hackers steal 31 million user records, including emails and hashed passwords. Learn how it happened.



Internet Archive Hacked, 31 Million Users Exposed


A sophisticated cyberattack rocked the official LEGO website, exposing the popular global brand to a high-stakes cryptocurrency scam. Hackers briefly seized control of the platform, promoting a fraudulent LEGO Coin that could be purchased with Ethereum. 

The event, which lasted 75 minutes, sent shockwaves through the cybersecurity world, raising eyebrows not only for its bold execution but also for the odd choice of targeting one of the world’s most trusted family-friendly brands.

### Attack: What Happened?

At approximately 9 PM EST, unsuspecting visitors to LEGO.com were greeted by a modified main banner promoting a new "LEGO Coin." This wasn't just any harmless image. The hackers crafted a seemingly legitimate ad, complete with the LEGO logo and promises of “secret rewards” for those who purchased the token.

The banner read:

> _"Our new LEGO Coin is officially out! Buy the new LEGO Coin today and unlock secret rewards!"_



For 75 minutes, this fraudulent campaign persisted, redirecting users to the Uniswap cryptocurrency platform. Here, the fake LEGO token could be purchased using Ethereum, luring in cryptocurrency enthusiasts and LEGO fans alike.

However, unlike many traditional cryptocurrency scams, this breach did not utilize a crypto drainer to immediately steal funds from connected wallets. Instead, the focus was on selling fake tokens. By 10:15 PM EST, LEGO’s web administrators regained control, removing the malicious banner and restoring normal operations.

### Damage Control: LEGO Responds

While the damage from the attack was limited, LEGO quickly moved to reassure customers. In a statement to SecureBlink Threat Researchers, LEGO confirmed the breach but kept the details on how hackers managed to access their system under wraps:

> _"On 5 October 2024, an unauthorized banner briefly appeared on LEGO.com. It was quickly removed, and the issue has been resolved. No user accounts have been compromised, and customers can continue shopping as usual. The cause has been identified, and we are implementing measures to prevent this from happening again."_



The company’s swift response helped alleviate customer fears, and they emphasized that no user accounts or personal information were compromised during the attack.

### Odd Choice: Why LEGO?

This attack left cybersecurity experts perplexed. Why LEGO? For such a high-profile brand with a vast, loyal customer base, many expected a more malicious payload. Hackers commonly exploit website breaches to:

- Inject malicious JavaScript to steal customer information (such as credit card data).

- Use the breach as a vector for data extortion.

- Sell stolen data on darknet marketplaces.


But in this case, the focus was a low-effort cryptocurrency scam, with only a handful of people purchasing the fake LEGO tokens, amounting to a few hundred dollars in revenue for the attackers. For the access they had, the scam’s execution and profit were both notably underwhelming.

### Bigger Picture: Website Vulnerabilities

This incident serves as a stark reminder of the vulnerabilities high-profile websites face, especially in an era where cryptocurrency scams are becoming increasingly rampant. Unlike the traditional methods of stealing customer data or injecting malware, this hack showcased a growing trend of brand exploitation through direct crypto schemes.

In recent years, phishing campaigns and supply chain attacks have given hackers a pathway to even the most secure websites. Once inside, the attackers can exploit a brand's reputation to give credibility to their scams—precisely what happened with LEGO.


While this attack on LEGO.com may not have resulted in massive financial damage or data loss, it highlights several key concerns:

1. No site is immune to attacks, no matter how robust its security protocols.


2. Brand reputation can be a powerful weapon in the hands of cybercriminals.


3. Cryptocurrency scams are evolving and using more creative methods to capture unsuspecting victims.


4. Companies must not only guard against data theft but also brand hijacking in the crypto space.

LEGO Website Hacked: Fake Crypto Coin Scam Shocks the Internet!



In early 2024, U.S. telecom giant Comcast confirmed that over 230,000 customers had their sensitive personal data stolen during a ransomware attack on Financial Business and Consumer Solutions (FBCS), a third-party debt collection agency based in Pennsylvania. This breach underscores the critical risks posed by outsourcing sensitive operations to external vendors and the pervasive threat of ransomware in the modern digital landscape.

### Incident Overview

The breach traces back to a cyberattack between February 14 and February 26, 2024, targeting FBCS’s systems. Initially, FBCS assured Comcast that no Comcast customer data had been compromised in the attack. However, in July 2024, FBCS revealed that the breach had, in fact, exposed data related to 237,703 Comcast customers. The stolen information includes:

- Names

- Addresses

- Social Security numbers

- Dates of birth

- Comcast account numbers

- Comcast ID numbers


These customers were primarily registered with Comcast around 2021, though Comcast had already stopped using FBCS for debt collection services by 2020.

### Attack Nature: Ransomware

The ransomware attack on FBCS involved unauthorized access to its computer network, during which time hackers downloaded sensitive data and encrypted several of FBCS’s systems. The perpetrators have not been identified, and no major ransomware group has claimed responsibility for the attack. FBCS’s own public statement only refers to the attacker as an “unauthorized actor.” The exact method of infiltration remains unknown, though typical vectors for ransomware attacks include phishing, malware, and exploiting known software vulnerabilities.

### Third-Party Vendor Vulnerability

This breach is a textbook example of the vulnerabilities introduced when organizations rely on third-party vendors to handle sensitive data. In this case, although Comcast’s internal systems were not directly compromised, the company became collateral damage through its association with FBCS. The incident reveals a significant flaw in many organizations' cybersecurity strategies: while internal systems may be well-protected, outsourced services—often considered secondary—may be more vulnerable.

FBCS’s failure to promptly disclose the involvement of Comcast’s data in the breach further highlights the communication breakdown that often occurs in vendor relationships. Comcast learned in March 2024 that there had been a ransomware attack on FBCS but was not informed about the exposure of its customers' data until several months later. This delay in notification likely exacerbated the potential damage to Comcast’s customers.

### Broader Impact and Related Breaches

The FBCS breach is part of a broader cyberattack that affected millions of individuals and several large organizations, demonstrating the wide-reaching impacts of such incidents. In total, FBCS reported that over 4 million people had their personal information compromised during the February 2024 ransomware attack.

CF Medical (Capio): A medical debt-purchasing company, CF Medical confirmed in September 2024 that more than 620,000 individuals had their health information, including medical claims, stolen in the breach. Health information is particularly sensitive, and the theft of such data heightens the risk of fraud and privacy violations.

Truist Bank: One of the largest banks in the U.S., Truist Bank confirmed that its customer data was also exposed during the attack, including names, addresses, account numbers, dates of birth, and Social Security numbers. Truist Bank, which has over 10 million customers, has yet to reveal how many of its customers were impacted, but the exposure of account and financial data raises concerns about potential identity theft and financial fraud.


### Regulatory and Legal Implications

The Comcast-FBCS breach has significant legal and regulatory consequences. Due to the type of data exposed—especially Social Security numbers and personal identification details—Comcast and FBCS are likely to face legal claims from affected customers. Both companies may also encounter regulatory scrutiny for their handling of the breach and the delayed notification of affected parties.

In the U.S., data breaches involving sensitive personal information often lead to class-action lawsuits, as seen in previous high-profile incidents. Comcast may be required to provide credit monitoring services and identity protection measures for affected individuals to mitigate the potential risks of identity theft. Additionally, as the incident involved multiple states, state attorneys general may investigate the breach, potentially leading to fines or sanctions for non-compliance with data protection laws, such as the California Consumer Privacy Act (CCPA) or the Maine Data Protection Act.

### Role of FBCS in the Breach

FBCS's role as the third-party vendor at the center of this breach cannot be overlooked. Despite their responsibility for protecting customer data, FBCS failed to secure critical information from its clients, including Comcast. Moreover, their delayed response and incomplete disclosure of the breach’s impact added to the potential damage for affected companies and individuals.

The situation calls for stricter regulatory oversight of third-party service providers, particularly those handling sensitive financial and medical data. Organizations like Comcast must ensure that their vendors adhere to robust cybersecurity frameworks and employ rigorous risk management practices.

### Comcast’s Response and Future Actions

Comcast’s decision to cease using FBCS for debt collection services in 2020 does not exempt it from responsibility for this breach. As the affected data dates back to 2021, Comcast will need to provide a clear explanation of how this older data was still in FBCS’s possession and what measures were in place to protect it.

In the wake of the breach, Comcast will likely implement additional measures to secure its data when working with third-party vendors. This includes:

Vendor Audits: Routine cybersecurity audits of all third-party vendors to ensure they comply with the company's data protection standards.

Data Encryption: Ensuring that all sensitive data—both at rest and in transit—is encrypted, even when stored by external service providers.

Stricter Contract Provisions: Future contracts with vendors may include stronger security requirements and financial penalties for breaches.


### Lessons for the Industry

The Comcast-FBCS ransomware incident serves as a crucial reminder to industries relying on third-party services for sensitive operations. The breach highlights the importance of:

- 1. Comprehensive Vendor Risk Management: Organizations must adopt a proactive approach to managing vendor risks. This includes regular assessments of third-party cybersecurity capabilities and imposing strict data protection requirements.


- 2. Faster Incident Response and Transparency: Companies should demand timely breach notifications and transparent communication from their vendors to mitigate the risks of delayed responses and greater customer harm.


- 3. Holistic Cybersecurity Strategies: Organizations must consider the full spectrum of their cybersecurity defenses, including vendor-related risks. Ensuring that external partners meet the same security standards as internal systems can significantly reduce exposure.

Massive Comcast Data Breach Exposes 230,000+ Customers' Personal Info!

The MoneyGram cyberattack in September has highlighted a glaring reality: even the most established financial giants are not immune to advanced cyber intrusions. 

This wasn’t just a minor hiccup—MoneyGram’s extensive global operations, spanning over 200 countries with 350,000 physical locations, were paralyzed for five days. 

Customers found themselves locked out, unable to access or transfer funds, igniting widespread concern. Initially, many speculated ransomware as the likely culprit—a standard conclusion given the surge of such attacks in recent years. However, after working closely with cybersecurity experts and law enforcement, MoneyGram firmly denied any connection to ransomware. 

While this might offer temporary relief, the lack of transparency and concrete details raises an unsettling question: if it wasn’t ransomware, what kind of threat are we dealing with? The absence of clear answers leaves the door open to even more complex and potentially dangerous vulnerabilities that remain concealed beneath the surface.


### September Breach: Disruption & Chaos

On September 20, MoneyGram's services were abruptly halted, with customers unable to transfer funds or access vital services for five days. The company acted quickly, taking systems offline to contain the breach, and it wasn't until September 25 that operations resumed. Despite whispers of a ransomware attack, MoneyGram vehemently denied this, stating, “At this time, we have no evidence that this issue involves ransomware.” Yet, behind this reassurance lies a deeper, more disturbing narrative involving a hacker collective known as Scattered Spider.

### Rise of Scattered Spider

To understand the gravity of this situation, we must travel back to a series of attacks in recent history. Scattered Spider, a hacker group with a reputation for its sophisticated social engineering attacks, made headlines in September 2023 after its audacious breach of MGM Resorts. With a cunning impersonation tactic, they called the resort's IT help desk, posing as employees to reset a password, eventually gaining access to the entire network. In the blink of an eye, Scattered Spider deployed BlackCat ransomware, encrypting hundreds of critical servers, causing a digital blackout that reverberated through the casino and resort giant.

This attack, while devastating, was not isolated. In fact, Scattered Spider's modus operandi is to target organizations using similar social engineering methods. Their precision and deep understanding of corporate systems have left a trail of chaos across various industries. What’s most troubling is that the tactics used against MGM appear eerily similar to those seen in MoneyGram’s breach.

### Social Engineering: Silent Killer

MoneyGram’s breach, while not linked directly to ransomware, shares a disturbing parallel with previous Scattered Spider attacks. According to insiders, the attackers gained access through a social engineering attack on the company’s internal help desk. An employee’s credentials were compromised, allowing the intruders to access critical employee information in MoneyGram's Windows Active Directory Services. Although swift action prevented further damage, this breach could easily have spiraled into something far more catastrophic.

This is the signature of Scattered Spider. Their hallmark is not brute force or sophisticated malware but rather the subtle manipulation of human trust—a vulnerability far harder to patch. By exploiting human error, they bypass even the most stringent cybersecurity defenses, gaining access to systems that would otherwise be impregnable.

### Unanswered Questions

While MoneyGram has downplayed the event, stating that "no further damage" was done and that "the majority of our systems are now operational," there remain lingering concerns. The company’s assurance that the breach wasn’t tied to ransomware is comforting, but the very fact that such a significant platform fell prey to a social engineering attack sends a ripple of fear through the financial industry.

MoneyGram has yet to publicly name the attackers, but the similarity in attack strategies to those employed by Scattered Spider leaves little room for doubt. This hacker collective has evolved, moving from resort giants like MGM to financial behemoths like MoneyGram. Are they sending a message? Are they honing their skills, biding their time until they can strike again with even greater ferocity?

### A History of Chaos

Scattered Spider has been a thorn in the side of cybersecurity for years. Their attacks, dating back to their earlier incarnation as UNC3944, have been marked by meticulous planning and a deep understanding of the corporate systems they breach. They move silently, often remaining undetected until it’s too late.

The MGM attack was a defining moment, one that brought Scattered Spider into the limelight. With Microsoft, the FBI, CISA, and cybersecurity firm Mandiant issuing warnings about the group’s tactics, the world took notice. Yet, despite these advisories, the group continues to wreak havoc. Their ability to adapt and evolve, to learn from their past attacks and refine their techniques, makes them one of the most dangerous hacker collectives in the world today.

### A Warning to All

The attack on MoneyGram serves as a stark reminder that no company, no matter how large or how secure they may seem, is immune to the threat of cybercrime. The financial industry, in particular, stands at a precipice. With vast amounts of sensitive data and billions of dollars at stake, the risk of another breach—potentially more damaging than this one—looms large.

For now, MoneyGram can breathe a sigh of relief. Their systems are back online, and their customers can once again transfer funds. But the damage has been done. Trust has been shaken, and the specter of Scattered Spider continues to hover over the financial world like a shadowy figure waiting for its next victim.

As we move into an era where digital transactions become the lifeblood of the global economy, companies must remain vigilant. The tactics of groups like Scattered Spider will only grow more sophisticated. Today, it's MoneyGram. Tomorrow, it could be anyone. And in this ever-evolving game of cat and mouse, it’s clear that the hackers are always one step ahead.

The intersection of MoneyGram and Scattered Spider is not just to be cautious—it’s a rather a rock bottom hit. We are at war with cybercriminals who do not need guns or bombs to cause devastation. All they need is a phone call, a little bit of deception, and a world of havoc follows. The question now shouldn't be who will be next?

The Common Unix Printing System (CUPS) is a widely used open-source printing system that manages print jobs and queues on Unix-like operating systems. While essential for network printing, CUPS can introduce security vulnerabilities if not properly managed. Recent disclosures have highlighted vulnerabilities within CUPS that threat actors could exploit to launch distributed denial-of-service (DDoS) amplification attacks. This comprehensive analysis delves into the intricacies of these vulnerabilities, their exploitation mechanisms, and mitigation strategies to safeguard affected systems.


---

### Understanding CUPS

CUPS provides a modular printing system that enables a computer to act as a print server. It uses the Internet Printing Protocol (IPP) and supports various printing services, making it integral to many network environments. However, its widespread adoption also makes it a target for cyber threats.


---

### Overview of the Vulnerabilities

Vulnerability in cups-browsed Daemon

The cups-browsed daemon is responsible for browsing remote printers and adding them to the local print system. A vulnerability within this daemon allows attackers to send specially crafted packets that trick the CUPS server into treating a target device as a printer to be added.

### Exploitation via Malicious UDP Packets

Attackers can exploit this vulnerability by sending a single malicious UDP packet to an exposed CUPS service. This packet initiates a series of unintended actions by the CUPS server, leading to DDoS amplification.


---

### Mechanism of DDoS Amplification

#### Amplification Factor

Each malicious packet sent to a vulnerable CUPS server causes it to generate larger IPP/HTTP requests to the target device. This results in a significant amplification of traffic—up to 600 times the size of the initial packet.

#### Impact on Servers and Networks

**Bandwidth Consumption:** The amplified traffic consumes considerable bandwidth, potentially overwhelming the target's network capacity.

**Resource Exhaustion:** Both the CUPS server and the target device experience increased CPU and memory usage.

**Infinite Request Loops:** In some cases, CUPS servers enter an infinite loop, continuously sending requests and exacerbating the attack's impact.



---

### Scope of the Vulnerability

#### Exposed and Vulnerable Servers

Security researchers estimate that a significant number of CUPS servers are exposed online, with thousands running outdated versions dating back to 2007. These outdated systems lack critical security patches, making them susceptible to exploitation.

#### Potential for Botnet Recruitment

Cybercriminals can exploit these vulnerabilities to build botnets for more extensive DDoS attacks or achieve remote code execution (RCE) by chaining multiple vulnerabilities.


---

### Technical Analysis of the Exploit

- **1. Initial Probe:** The attacker sends a crafted UDP packet to the vulnerable CUPS server.


- **2. Triggering Printer Addition:** The server misinterprets the packet, attempting to add the target as a new printer.


- **3. Amplified Request Generation:** The server sends larger IPP/HTTP requests to the target device.


- **4. Resource Drain:** Repeated requests lead to bandwidth and CPU resource exhaustion on both the server and the target.


- **5. Infinite Loop Scenarios:** Certain errors can cause the server to repeatedly attempt connections, creating an endless loop of traffic.




---

### Mitigation Strategies

#### Apply Security Patches

***Update CUPS***: Ensure that the CUPS software is updated to the latest version, incorporating all security patches that address known vulnerabilities.


#### Disable Unnecessary Services

***Stop cups-browsed Daemon***: If not required, disable the cups-browsed service to eliminate the attack vector.

`sudo systemctl stop cups-browsed`
`sudo systemctl disable cups-browsed`


#### Implement Network Access Controls

***Firewall Configuration:*** Restrict access to CUPS services using firewalls to allow only trusted networks or hosts.

***UDP Traffic Limitation:*** Limit or monitor UDP traffic to and from CUPS servers.


#### Monitor and Detect Anomalous Activity

***Intrusion Detection Systems***: Deploy IDS/IPS solutions to detect and prevent exploitation attempts.

***Log Analysis***: Regularly review system logs for unusual activity related to CUPS services.


### Educate and Train Staff

The colossal assault was part of a sustained campaign spanning over a month, during which more than 100 hyper-volumetric DDoS attacks were launched. These attacks aimed to overwhelm network infrastructure by inundating it with massive amounts of illegitimate traffic, thereby consuming bandwidth and depleting system resources. This deluge of data effectively denied legitimate users access to services, fulfilling the primary objective of a DDoS attack.

### Technical Anatomy of the Attack

The attacks primarily targeted the network and transport layers (Layers 3 and 4) of the OSI model. Many of these assaults surpassed two billion packets per second (pps) and exceeded bandwidths of 3 Tbps. The threat actors orchestrated the campaign using a diverse array of compromised devices, including:

- Asus Home Routers

- MikroTik Systems

- Digital Video Recorders (DVRs)

- Web Servers


These infected devices formed a global botnet with significant concentrations in Russia, Vietnam, the United States, Brazil, and Spain.

### UDP Exploitation on Fixed Ports

The attackers predominantly utilized the User Datagram Protocol (UDP) on fixed ports to transmit data. UDP is favored in such attacks due to its connectionless nature, allowing rapid transmission without the overhead of establishing a formal connection, thus amplifying the attack's speed and volume.

### Cloudflare's Autonomous Defense Mechanism

Cloudflare's advanced DDoS mitigation infrastructure autonomously detected and neutralized all the attacks in real-time. The peak attack, which hit 3.8 Tbps, lasted approximately 65 seconds. The company's ability to withstand such a massive onslaught without manual intervention highlights the effectiveness of its automated defense systems and the importance of robust cybersecurity measures.

### Global Distribution of Attack Sources



### Infected devices were distributed globally, with hotspots in key regions.

#### Comparative Analysis with Previous Records

Before this incident, the record for the largest publicly disclosed volumetric DDoS attack was held by Microsoft, which mitigated a 3.47 Tbps attack targeting an Azure customer in Asia. Cloudflare's recent mitigation surpasses this figure, indicating a troubling increase in the scale at which malicious actors are operating.

#### Emerging Threats: The CUPS Vulnerability

In a related development, cybersecurity firm Akamai has identified that recently disclosed vulnerabilities in the Common UNIX Printing System (CUPS) for Linux could serve as a new vector for DDoS attacks. Akamai's research revealed:

#### Over 58,000 publicly accessible systems vulnerable to CUPS exploitation.

These systems could be co-opted to send thousands of requests in amplification attacks.

Some CUPS servers responded repeatedly to initial requests, potentially leading to endless loops of malicious traffic.


### Implications for Cybersecurity

The escalation in both the scale of attacks and the exploitation of new vulnerabilities like CUPS underscores the evolving threat landscape. Organizations must adopt proactive and adaptive security strategies, including:

Investing in Automated Defense Systems: As demonstrated by Cloudflare, autonomous mitigation can effectively neutralize large-scale attacks without human intervention.

Regular Vulnerability Assessments: Identifying and patching vulnerabilities like those in CUPS can prevent systems from being exploited in botnets.

Global Collaboration: Sharing threat intelligence across industries and borders is crucial for anticipating and defending against emerging threats.




Cloudflare's successful mitigation of the largest recorded DDoS attack serves as both a warning and a call to action. As cyber threats continue to grow in scale and complexity, the importance of robust, automated, and adaptive cybersecurity measures cannot be overstated. Organizations worldwide must remain vigilant and collaborative to safeguard the integrity of global digital infrastructure.

Cloudflare Mitigates Largest Recorded DDoS Attack Peaking at 3.8 Tbps

Cybersecurity researchers have disclosed a new, sophisticated cryptojacking campaign that targets the [Docker](https://www.secureblink.com/cyber-security-news/new-cyberattack-targets-docker-ap-is-with-advanced-cryptojacking-tactics-1) Engine API to hijack cloud resources and create a malicious Docker Swarm botnet.

In a detailed Datadog Security Research analysis, attackers exploit unauthenticated and exposed Docker Engine API endpoints to deploy cryptocurrency miners on compromised containers. By leveraging Docker Swarm's orchestration features for command-and-control (C2) purposes, the attackers effectively turn compromised systems into coordinated botnets.

This [Threatfeed](https://www.secureblink.com/cyber-security-news) delves into the mechanics of the critical cryptojacking attack, the tools, and scripts leveraged by the threat actors, and provides comprehensive recommendations for safeguarding against such threats.

## Understanding the Attack Vector

### Initial Access via Exposed Docker APIs

Attackers initiate the campaign by scanning the internet for exposed Docker Engine API endpoints using tools like **masscan** (a fast port scanner) and **ZGrab** (an application layer scanner). These endpoints, typically listening on ports **2375**, **2376**, **2377**, **4243**, and **4244**, can be unauthenticated and, if misconfigured, provide root-level access to the host.

**Quote from Datadog's Report:**

> "We have discovered a new cryptojacking campaign targeting Docker Engine API, with the ability to move laterally to Docker Swarm, Kubernetes, and SSH servers." — [Datadog Security Research](https://securitylabs.datadoghq.com/articles/threat-actors-leveraging-docker-swarm-kubernetes-mine-cryptocurrency/)

### Deployment of Malicious Containers

Once an exposed API is found, the attackers spawn an Alpine Linux container with the host's filesystem mounted inside. This container retrieves an initialization shell script (`init.sh`) from a remote server (`solscan[.]live`). The script performs several actions:

- Ensures data transfer tools like `curl` and `wget` are installed.
- Checks for root privileges.
- Downloads and executes the **XMRig** miner for cryptocurrency mining.
- Installs a custom **libprocesshider** rootkit to hide malicious processes.

### Hiding Malicious Activity

The **libprocesshider** rootkit is employed to conceal the **XMRig** miner process from system monitoring tools like `top` and `ps`, making it difficult for administrators to detect unusual activity.

## Lateral Movement and Propagation

### Additional Payloads and Scripts

The `init.sh` script also fetches additional scripts for lateral movement:

1. **`kube.lateral.sh`**: Targets Kubernetes environments.
2. **`spread_docker_local.sh`**: Scans local network ranges for other Docker hosts.
3. **`spread_ssh.sh`**: Attempts to spread via SSH by adding authorized keys and creating new users.

### Targeting Kubernetes with `kube.lateral.sh`

The script disables security measures like firewalls and SELinux before scanning local network ranges for open **Kubelet API** ports (10250). If vulnerable Kubernetes nodes are found, it can execute commands to deploy the miner on pods running on those nodes.

### Scanning and Exploitation with `spread_docker_local.sh`

- Uses `masscan` and `zgrab` to find hosts with open Docker-related ports.
- Deploys malicious containers on discovered hosts using images hosted on Docker Hub by user **nmlmweb3**.
- The images execute `init.sh`, propagating the malware.

### SSH Backdoors with `spread_ssh.sh`

- Scans for SSH servers on the local network.
- Adds a new SSH key and creates a new user named **ftp** with root privileges.
- Searches for credential files related to SSH, AWS, Google Cloud, and Samba, particularly targeting GitHub Codespaces environments.
- Uploads any found credentials to the C2 server.

### Manipulating Docker Swarm with `TDGINIT.sh`

- Forces compromised Docker hosts to leave existing Swarms.
- Joins them to a new Swarm controlled by the attacker using a predefined token.
- Allows attackers to use Docker Swarm's orchestration for C2, issuing commands across all compromised nodes.

## Persistence Mechanisms

### Process Hiding and Dynamic Linker Hijacking

- Uses **Dynamic Linker Hijacking** by modifying `/etc/ld.so.preload` to ensure the rootkit is loaded for every new process.
- Hides the **XMRig** miner process, preventing detection.

### Cron Jobs and Immutable Files

- Installs cron jobs to maintain persistence.
- Uses the `chattr +ai` command to make backdoor files immutable, preventing their removal or modification.

## Broader Implications

### Threat to Cloud Infrastructure

This campaign highlights significant risks:

- **Resource Drain**: Cryptocurrency mining consumes substantial CPU and memory resources, affecting performance and increasing costs.
- **Security Risks**: Attackers with root access can exfiltrate data, install additional malware, or use the infrastructure for further attacks.
- **Botnets**: Compromised hosts can be coordinated for distributed denial-of-service (DDoS) attacks or other malicious activities.

### Potential Attribution to TeamTNT

While some tactics resemble those of **[TeamTNT](https://www.secureblink.com/cyber-security-news/teamtnt-targets-compromised-docker-hub-accounts-to-distribute-crypto-mining-malware)**, a known threat group specializing in cloud-focused attacks, definitive attribution remains uncertain.

## Recommendations for Prevention and Mitigation

1. **Secure Docker API Endpoints**:

   - Do not expose the Docker Engine API to the internet.
   - Secure it with TLS authentication and firewall rules.

2. **Regularly Update and Patch Systems**:

   - Keep Docker, Kubernetes, and associated services updated.
   - Apply security patches promptly.

3. **Monitor Network Traffic and Logs**:

   - Use intrusion detection systems (IDS) to monitor for unusual activity.
   - Be alert for large outbound traffic volumes indicative of cryptomining or data exfiltration.
   - Regularly check system logs for unauthorized modifications.

4. **Implement Principle of Least Privilege**:

   - Limit user permissions and avoid running containers as root when possible.
   - Use role-based access control (RBAC) in Kubernetes.

5. **Use Security Tools and Best Practices**:

   - Employ tools like Docker Bench Security to assess the security posture.
   - Utilize cloud security posture management (CSPM) solutions for continuous monitoring.
   - Enable logging and monitoring features in Docker and Kubernetes.

6. **Educate and Train Staff**:

   - Ensure that DevOps and IT teams are aware of security best practices for containerized environments.
   - Conduct regular security awareness training.

7. **Audit and Secure Credentials**:

   - Regularly audit credentials and keys stored in environments like GitHub Codespaces.
   - Use secrets management tools to store sensitive information securely.

## Conclusion

The discovery of this cryptojacking campaign underscores the critical need for securing containerized environments. Exposed Docker APIs and misconfigured Kubernetes clusters present significant risks, enabling attackers to mine cryptocurrency and establish botnets for broader malicious activities.

Organizations must proactively secure their Docker and Kubernetes environments, regularly audit configurations, and stay informed about emerging threats. By implementing robust security measures and educating staff, the risk of such attacks can be significantly mitigated.

## Indicators of Compromise (IOCs)

- **Files and Scripts**:

  - `init.sh`, `kube.lateral.sh`, `spread_docker_local.sh`, `spread_ssh.sh`, `ar.sh`, `TDGINIT.sh`, `pdflushs.sh`
  - Use of `libprocesshider` rootkit

- **Domains and IPs**:

  - `solscan.live`
  - `147.75.47.199`
  - Docker Hub user `nmlmweb3`

- **Ports Targeted**:

  - Docker ports: 2375, 2376, 2377, 4243, 4244
  - Kubernetes Kubelet API port: 10250
  - SSH port: 22

This Threatfeed is the first in a series exploring vulnerabilities in Unix systems, specifically targeting GNU/Linux systems through the Common Unix Printing System (CUPS). As noted by a contributor to the CUPS project:

> _"From a generic security point of view, a whole Linux system as it is nowadays is just an endless and hopeless mess of security holes waiting to be exploited."_

This statement underscores the critical need to examine and address these vulnerabilities to enhance system security.

---

## Summary

Several vulnerabilities have been identified in CUPS and its associated components, which, when combined, allow for remote code execution (RCE) on affected systems:

- **CVE-2024-47176**: `cups-browsed` versions ≤ 2.0.1 bind to UDP `INADDR_ANY:631`, accepting packets from any source, which can trigger a `Get-Printer-Attributes` IPP request to an attacker-controlled URL.

- **CVE-2024-47076**: `libcupsfilters` versions ≤ 2.1b1 have a vulnerability where `cfGetPrinterAttributes()` does not validate or sanitize IPP attributes returned from an IPP server, allowing attacker-controlled data into the CUPS system.

- **CVE-2024-47175**: `libppd` versions ≤ 2.1b1's `ppdCreatePPDFromIPP2()` function fails to validate or sanitize IPP attributes when writing them to a temporary PPD file, enabling injection of attacker-controlled data.

- **CVE-2024-47177**: `cups-filters` versions ≤ 2.0.1 include `foomatic-rip`, which allows arbitrary command execution via the `FoomaticRIPCommandLine` PPD parameter.

---

## Impact

A remote, unauthenticated attacker can silently replace existing printers or install new ones by manipulating IPP URLs with malicious ones. This manipulation can lead to arbitrary command execution on the target system when a print job is initiated.

---

## Attack Vectors

### Public Internet (WAN)

- An attacker sends a crafted UDP packet to port **631** on the target system.
- No authentication is required.
- This vector affects systems directly connected to the internet with port 631 exposed.

### Local Network (LAN)

- An attacker can spoof Zeroconf, mDNS, or DNS-SD advertisements to achieve the same result.
- This method will be elaborated in subsequent write-ups focusing on macOS.

---

## Affected Systems

The vulnerabilities affect a wide range of Unix-like systems where CUPS and `cups-browsed` are installed:

- **Most GNU/Linux distributions**
- **Some BSD variants**
- **Oracle Solaris**
- **Potentially Google ChromeOS**
- **Other Unix-like operating systems**

*Note:* The presence and default status of `cups-browsed` may vary across distributions.

---

## Technical Details

### Vulnerability in `cups-browsed` (CVE-2024-47176)

- **Issue:** `cups-browsed` listens on UDP port 631 on all network interfaces (`0.0.0.0`), accepting packets from any source.
- **Risk:** An attacker can send a specially crafted packet to trigger a `Get-Printer-Attributes` IPP request to an attacker-controlled URL.
- **Cause:** Lack of source IP address validation due to default configuration allowing all connections.

### Lack of Input Validation in `libcupsfilters` (CVE-2024-47076)

- **Issue:** The function `cfGetPrinterAttributes5()` does not validate or sanitize IPP attributes received from a server.
- **Risk:** Attacker-controlled data can be injected into the CUPS system, potentially leading to malicious activities.
- **Cause:** Insufficient validation of IPP attributes returned from remote servers.

### Improper Handling in `libppd` (CVE-2024-47175)

- **Issue:** The function `ppdCreatePPDFromIPP2()` fails to validate or sanitize IPP attributes when writing to a temporary PPD file.
- **Risk:** Allows injection of malicious directives into PPD files, which can be executed by the system.
- **Cause:** Lack of proper input sanitization when generating PPD files from IPP attributes.

### Arbitrary Command Execution via `foomatic-rip` (CVE-2024-47177)

- **Issue:** The `foomatic-rip` filter allows execution of arbitrary commands through the `FoomaticRIPCommandLine` parameter in PPD files.
- **Risk:** An attacker can execute commands with the privileges of the CUPS system, potentially leading to full system compromise.
- **Cause:** Historical reliance on `foomatic-rip` for printer compatibility, with challenges in restricting its capabilities without breaking functionality.

---

## Exploitation Overview

By chaining the identified vulnerabilities, an attacker can:

1. **Trigger a Malicious IPP Request:**
   - Send a crafted UDP packet to UDP port 631, causing `cups-browsed` to initiate a connection to an attacker-controlled IPP server.

2. **Inject Malicious IPP Attributes:**
   - The attacker's IPP server responds with malicious attributes that are not validated by `libcupsfilters` or `libppd`.

3. **Create Malicious PPD File:**
   - The system generates a PPD file containing injected directives, including potentially harmful commands.

4. **Execute Arbitrary Commands:**
   - When a user initiates a print job, the CUPS system processes the PPD file, executing the injected commands via `foomatic-rip`.

*Note:* User interaction is required (i.e., starting a print job) for the final execution step.

---

## Remediation

### Immediate Actions

- **Disable `cups-browsed`:**
  - If not required, stop and disable the `cups-browsed` service:
    ```bash
    sudo systemctl stop cups-browsed
    sudo systemctl disable cups-browsed
    ```
- **Update CUPS Packages:**
  - Apply security updates from your distribution's repositories as they become available.

- **Network-Level Mitigation:**
  - Block incoming traffic on UDP port 631 at the firewall level.

Critical CUPS Vulnerability Exposes Unix Systems to Remote Attacks

The Cybersecurity and Infrastructure Security Agency (CISA) alerts critical infrastructure operators of ongoing attacks exploiting Internet-exposed OT and ICS devices using unsophisticated methods like default credentials and brute-force attacks.*

---

The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning about threat actors attempting to breach critical infrastructure networks by targeting Internet-exposed Operational Technology (OT) and Industrial Control Systems (ICS) devices. These attackers are employing unsophisticated methods such as brute-force attacks and exploiting default credentials to gain unauthorized access.

According to CISA, these ongoing attacks are particularly impacting the Water and Wastewater Systems (WWS) sector but pose a threat to all critical infrastructure sectors. OT devices, which integrate hardware and software to monitor and control physical processes in industries like manufacturing and utilities, are essential for maintaining operations such as water treatment, distribution, and pressure regulation.

_"CISA continues to respond to active exploitation of internet-accessible OT and ICS devices,"_ the agency stated. _"Exposed and vulnerable systems may allow cyber threat actors to use default credentials, conduct brute-force attacks, or employ other unsophisticated methods to access these devices and cause harm."_

### **Recommended Security Measures**

CISA urges operators of OT and ICS devices in critical infrastructure sectors to implement the following security measures:

- **Change Default Passwords:** Replace all default credentials with strong, unique passwords.
- **Enable Multi-Factor Authentication (MFA):** Implement MFA where possible to add an extra layer of security.
- **Network Segmentation:** Place Human-Machine Interfaces (HMIs) and other critical systems behind firewalls and ensure they are not directly accessible from the Internet.
- **Secure Remote Access Tools:** Harden Virtual Network Computing (VNC) and other remote access installations by limiting exposure and requiring strong authentication.
- **Regular Software Updates:** Keep all OT and ICS software up to date with the latest security patches.

### **Rising Threat Landscape**

Since 2022, threat actors—including pro-Russian hacktivist groups—have been targeting vulnerable OT devices to disrupt operations or cause nuisance effects, primarily using low-sophistication techniques. These attacks highlight the urgent need for improved cybersecurity practices within critical infrastructure sectors.

Recent incidents underscore the severity of the threat. A cyberattack on a water treatment facility in Arkansas City, Kansas, forced the facility to switch to manual operations. Additionally, the U.S. Environmental Protection Agency (EPA) has issued guidance to help WWS owners and operators evaluate and enhance their cybersecurity measures.

### **Government Actions**

In response to the escalating threats, the White House and EPA have called on state governors to bolster the cybersecurity defenses of water systems. The U.S. government has also sanctioned individuals involved in cyberattacks targeting the water sector, demonstrating a commitment to holding malicious actors accountable.

CISA warns critical infrastructure operators of ongoing attacks targeting Internet-exposed OT and ICS devices using unsophisticated methods like default credentials & brute-force attacks.

CISA Warns of Unsophisticated Attacks Targeting Critical Infrastructure OT & ICS Devices


The Android ecosystem has once again fallen victim to a sophisticated and widespread malware infection. The latest threat, a variant of the Necro malware, has reportedly infiltrated 11 million devices via apps distributed on Google Play. Disguised through malicious advertising Software Development Kits (SDKs), Necro has made its way into legitimate apps, modded versions of popular software, and game mods. This technical breakdown delves into the infection's mechanism, impact, and remediation.

### Necro Malware: A Complex Threat

The Necro Trojan represents a multi-faceted and continuously evolving malware. Leveraging compromised SDKs in legitimate apps, the malware has extended its reach far beyond traditional distribution methods. The malicious SDK supply chain attacks employed by Necro highlight the growing sophistication of adversaries targeting mobile ecosystems.

#### Key Features of Necro's Latest Campaign:

1. Malicious Payloads: Necro installs various payloads designed to:

Display adware through invisible WebView windows.

Download and execute arbitrary JavaScript and DEX files.

Enable subscription fraud via specialized plugins.

Utilize infected devices as proxies to route malicious traffic.



2 Targeted Apps: Two legitimate apps on Google Play were infected:

Wuta Camera (by ‘Benqu’) with over 10 million downloads.

Max Browser (by 'WA message recover-wamr') with 1 million downloads.



3. Modded Popular Software: Necro also spreads through modified versions of popular apps like WhatsApp (GBWhatsApp, FMWhatsApp) and Spotify Plus, further amplifying its infection vector.



### Necro’s Infection Mechanism

Necro's infection vector operates in multiple stages, with malicious SDKs serving as the initial point of compromise. Legitimate apps incorporate SDKs for monetization through ads, but in this case, the SDKs had been weaponized.

Stage 1: Coral SDK, the malicious SDK responsible for delivering the first payload, employs obfuscation techniques to evade detection and uses image steganography to download the second-stage payload disguised as a PNG image.

Stage 2: The second payload, called shellPlugin, facilitates deeper system penetration, allowing for additional malicious operations, including:

Ad injection using hidden WebViews.

Silent installation of apps and APKs.

Interaction with paid services for fraudulent revenue generation.



### Impact on Users and Devices

The malicious actions performed by the Necro Trojan not only invade user privacy but also burden the infected device with unwanted processes. Some of the direct impacts include:

Unwanted Advertisements: Necro uses invisible WebView windows to interact with ad services in the background, generating fraudulent ad revenue.

Silent App Installations: Users unknowingly have apps or APKs installed on their devices, potentially leading to further malware infections or unwanted apps that consume device resources.

Subscription Fraud: Through hidden WebViews, Necro interacts with premium services, charging users without their knowledge.

Proxy Exploitation: Infected devices act as proxies to route malicious traffic, which could be leveraged for DDoS attacks, data exfiltration, or other nefarious purposes.


Affected Apps and Platforms

The two major legitimate apps identified with the Necro infection were:

1. Wuta Camera:

Downloads: Over 10 million downloads on Google Play.

Infected Versions: Version 6.3.2.148 was compromised, and the infection remained until version 6.3.6.148. Kaspersky notified Google, and the malware was removed in version 6.3.7.138. However, previously installed payloads remain active on devices with older app versions.



2. Max Browser:

Downloads: 1 million downloads on Google Play.

Current Status: Kaspersky reported that version 1.2.0 of Max Browser remains infected, and users are advised to uninstall the app as there is no clean version available.




Beyond Google Play, unofficial app repositories and modded apps have become a significant distribution vector for Necro. Popular mods for apps such as WhatsApp (GBWhatsApp, FMWhatsApp), Spotify Plus, and various game mods (e.g., Minecraft, Stumble Guys, Car Parking Multiplayer) were found to carry the Necro loader.

Necro's Global Reach

The spread of Necro has been massive, with 11 million devices infected through Google Play alone. However, the true extent of the malware’s distribution, particularly through modded apps on unofficial websites, remains unknown due to unreliable download data from those sources. Given the scale of these infections, the actual number could be far greater.

Mitigation and Recommendations

Users who have downloaded any of the affected apps, especially older versions, are urged to:

1. Uninstall the apps immediately: Apps like Wuta Camera (pre-version 6.3.7.138) and Max Browser should be removed from devices.


2. Run a security scan: Use a reputable mobile security solution to detect and remove any lingering payloads installed by the Necro Trojan.


3. Avoid unofficial app stores: Only download apps from trusted sources, such as the Google Play Store, but even then, be cautious and check app reviews and developer legitimacy.



For developers and companies, the malicious SDK supply chain attack serves as a stark reminder of the importance of SDK vetting and security audits. Ensuring that advertising and other third-party SDKs are secure and regularly updated can significantly reduce the risk of such infections.

Dell Investigates Alleged Data Breach After Hacker Leaks Employee Information up

A meeting of influential figures from the US and Taiwanese defense sectors was recently targeted by a sophisticated phishing attack carrying fileless malware. The incident, which comes just ahead of the 23rd US-Taiwan Defense Industry Conference, highlights the evolving nature of cyber-espionage and the increasing vulnerabilities posed by digital warfare.

The 23rd US-Taiwan Defense Industry Conference, set to take place in Philadelphia's Logan Square, will focus on critical topics such as US-Taiwan defense cooperation, defense procurement processes, and Taiwan's national security needs. The event, closed to the press, will gather speakers from the government, defense, academia, and commercial sectors, underscoring its importance to both nations' military strategies.

However, the recent phishing attack aimed at this high-profile event reveals much deeper concerns: the intersection of traditional defense strategies with emerging cyber threats, and how adversarial nations are exploiting these vulnerabilities in an age where digital information is as valuable as physical assets.

### Anatomy of the Attack

The US-Taiwan Business Council, the event organizer, was the target of a phishing attempt involving a fraudulent registration form. Embedded within this form was a sophisticated, fileless malware designed to execute entirely in memory, avoiding detection by most conventional antivirus tools. Thanks to the Council’s robust anti-phishing protocols, the attack was quickly neutralized.

According to an analysis by cybersecurity firm Cyble, the attackers disguised the malware within a seemingly legitimate PDF attached to an email, posing as a potential conference attendee. The ZIP file containing a malicious Windows shortcut (LNK) file would have established persistence by placing an executable file in the Windows startup folder, enabling additional payloads to be downloaded and executed in memory. This stealthy technique allows malware to evade traditional disk-based detection methods, making it an increasingly popular choice among advanced threat actors.

While the exact perpetrators remain unidentified, the attack fits a familiar pattern. Chinese-backed entities have a long history of targeting Taiwan with cyber-espionage efforts, particularly around high-stakes geopolitical events. As Kaustubh Medhe, head of research and intelligence at Cyble, pointed out, this latest attack may well be part of a broader strategy of long-term surveillance aimed at undermining US-Taiwan defense cooperation.

### Geopolitics Espionage

What’s striking about this attack is not just the technical sophistication of the malware, but the context in which it occurs. The US-Taiwan Defense Industry Conference comes at a time of heightened tensions in East Asia. Taiwan's strategic importance in the South China Sea and its growing defense relationship with the US make it a focal point for geopolitical competition, particularly as China seeks to assert its dominance in the region.

In this new landscape, traditional military posturing is increasingly complemented by digital warfare. Nation-states no longer need to deploy troops or ships to assert dominance; instead, they can undermine adversaries through cyber-attacks, surveillance, and the theft of sensitive information. The implications are profound: Is the very nature of warfare being reshaped by the cyber realm?

Cyber-espionage attacks like this one raise important questions about the future of international security. As governments increasingly rely on digital infrastructure to store sensitive information, the ability to protect this data has become as critical as safeguarding physical borders. The blurred lines between military and civilian targets—where an email can be as dangerous as a missile—forces us to reconsider how we define threats and defense.

### Fileless Malware: The Silent Saboteur of Modern Warfare

Fileless malware, like the one used in this attack, represents a significant evolution in cyber threats. Unlike traditional malware that writes files to a hard drive, fileless malware operates entirely within a system’s memory. This makes it particularly difficult to detect, as it leaves no trace on the disk, allowing attackers to lurk within a system unnoticed for extended periods.

This type of attack presents a critical challenge for organizations, especially those with limited resources or outdated cybersecurity protocols. As Lotta Danielsson, Vice President of the US-Taiwan Business Council, noted, “We have been targeted by these types of spear-phishing emails for over 20 years.” Yet, despite this long-standing threat, many organizations—particularly smaller ones—remain vulnerable.

Danielsson credits the Council’s success in thwarting these attacks to a combination of educational efforts and practical security measures. “Our staff is well-educated on these types of attacks. Nobody clicks links in emails or opens documents unless we’ve directly communicated with the sender. Even then, we scan them before opening,” she explained.

Moreover, the Council employs additional measures like air-gapping its systems during off-hours and maintaining relationships with cybersecurity professionals. These strategies, though effective for a small organization, may be difficult for larger enterprises to implement, raising a broader question: How can organizations of all sizes protect themselves in an era where cyber-espionage is increasingly pervasive?


As attacks like this become more frequent, they also force us to confront deeper ethical and strategic dilemmas. One of the most pressing issues is the increasingly blurred line between military and civilian targets in cyber warfare. Traditional conventions of war, like the Geneva Conventions, do not easily apply to cyber-attacks, which can disrupt civilian infrastructure, steal private data, or undermine national security without a single bullet being fired.

How should international law evolve to account for this new kind of warfare? What responsibilities do nations have to defend not only their military assets but also the civilian sectors that are often collateral damage in these digital skirmishes?

Another critical issue is the role of private companies in national defense. As cybersecurity becomes a cornerstone of defense strategy, private firms like Cyble, along with commercial defense contractors, play an outsized role in national security. This raises complex questions about accountability, transparency, and the privatization of national defense. Is it acceptable for national security to rest in the hands of private enterprises, especially when they may not be held to the same standards as government agencies?

### Future of Cyber-Warfare and International Security

The phishing attack targeting the US-Taiwan Defense Industry Conference is a textbook example of how digital threats have become an integral part of geopolitical strategy. As fileless malware and other advanced cyber threats continue to evolve, so too must our understanding of what constitutes security and defense in the 21st century.

This incident underscores a growing reality: The future of warfare is as much about bytes as it is about bullets. Governments, corporations, and individuals alike must grapple with the implications of this new battlefield, where an email attachment can do as much damage as a missile, and where cyber-espionage can shift the balance of power between nations.

As cyber threats grow in complexity, so too must the defenses we employ to counter them. Educational initiatives, robust cybersecurity protocols, and a deeper understanding of the geopolitical stakes are essential. However, the broader question remains: Are we prepared for a future where the boundaries between war and peace are no longer physical, but digital?

This phishing attack may have been thwarted, but it serves as a reminder that the cyber battlefield is constantly shifting—and that vigilance, education, and innovation are our best defenses against a world where threats can appear with the click of a mouse.

Phishing Espionage Attack Targets US-Taiwan Defense Conference

Over 1,000 ServiceNow Instances Found Leaking Corporate Knowledge Base Data: A Comprehensive Analysis

Introduction

A recent report has revealed that over 1,000 ServiceNow instances are misconfigured, leading to the unintentional exposure of sensitive corporate Knowledge Base (KB) data. These instances contain valuable organizational information, ranging from Personally Identifiable Information (PII) to internal credentials and access tokens, which could be exploited by malicious actors. Despite ServiceNow’s efforts to address these issues in their 2023 update, the misconfiguration of access controls remains a prevalent risk for organizations relying on the platform for managing their digital workflows.

### What is ServiceNow?

ServiceNow is a cloud-based platform designed to facilitate various digital workflows, integrating IT service management, operations, HR tasks, customer service, and security tools. One of its essential features is the Knowledge Base (KB), which serves as a repository for internal guides, procedures, and other articles meant to streamline operational efficiency. KBs provide critical resources for authorized users but can become a significant security liability if not properly configured.

### Misconfigured KBs and Data Exposure

Despite a 2023 ServiceNow security update aimed at preventing unauthorized access through new Access Control Lists (ACLs), many organizations failed to secure their KBs appropriately. The root cause lies in the User Criteria permission system, which many KBs rely on rather than ACLs, leading to a vulnerability that the 2023 update could not resolve.

A major concern is that public-facing widgets within the platform, used by organizations for customer-facing tasks, did not receive the ACL security patch. Consequently, unauthorized individuals can access KB articles, which are indexed incrementally, by brute-forcing Knowledge Base article numbers using basic tools like Burp Suite.

### Scope of the Exposure

According to Aaron Costello, Chief of SaaS Security Research at AppOmni, these exposed KB articles include sensitive organizational information such as:

Personally Identifiable Information (PII)

Internal system configurations

User credentials and tokens

Access details for live production systems


The severity of the issue varies across instances, but the presence of this kind of information represents a serious risk for the affected organizations. Knowledge Base articles are typically structured with predictable ID formats (e.g., KB0000001), making it easy for attackers to systematically brute-force these identifiers and potentially retrieve a significant amount of sensitive data.

### **The Proof-of-Concept Attack**

To demonstrate the severity of the misconfiguration, AppOmni developed a proof-of-concept (PoC) attack that showed how an unauthenticated external user could query public-facing widgets on a ServiceNow instance and retrieve KB article data by brute-forcing incremental article IDs. This vulnerability exploits the fact that ServiceNow instances often do not have stringent access controls, particularly when public widgets are involved.

The attack begins by intercepting a token used for querying the ServiceNow instance, and then brute-forcing the article IDs until the attacker retrieves KB articles that were inadvertently exposed due to misconfigured permissions.

Mitigating the Risk: Best Practices for Securing ServiceNow KBs

To prevent unauthorized access to KB articles, organizations using ServiceNow are urged to implement specific security measures. AppOmni recommends the following actions to protect KB data:

1. User Criteria Configuration

ServiceNow administrators should ensure that the User Criteria is correctly set to restrict access based on defined roles. Misconfigurations, such as leaving criteria like "Any User" or _"Guest User"_ enabled, make KB articles vulnerable to external access.

2. Turn Off Public Access

If public access to KB articles is unnecessary, it is advisable to turn off this feature entirely. This will eliminate the risk of exposing sensitive data on the internet.

3. Implement Security Controls

Organizations should activate the following ServiceNow security properties to protect KBs:

glide.knowman.block_access_with_no_user_criteria (True): This ensures that no user, whether authenticated or unauthenticated, can access KB articles if User Criteria is not explicitly defined.

glide.knowman.apply_article_read_criteria (True): This property enforces that even users with _"Can Contribute"_ permissions cannot read KB articles unless they are explicitly given "Can Read" access.

glide.knowman.show_unpublished (False): Disables access to draft or unpublished KB articles, which often contain unreviewed, sensitive information.

glide.knowman.section.view_roles.draft (Admin): Ensures that only users with administrative roles can access KB articles in a draft state.

glide.knowman.section.view_roles.review (Admin): Restricts access to KB articles under review to specific administrative roles.


4. Pre-built Out-of-the-Box (OOB) Rules

ServiceNow offers pre-configured OOB rules that automatically add Guest Users to the "Cannot Read" list for newly created KB articles. Enabling these rules will ensure that public access to KBs is restricted by default.

### ServiceNow's Response

In response to this issue, ServiceNow has acknowledged the potential for KB misconfigurations and has initiated steps to mitigate the risk. As of September 4, 2024, ServiceNow began proactively assisting customers with configuring their KBs to better align with security best practices. A ServiceNow spokesperson emphasized the company’s commitment to ongoing customer support and extensible security protocols to ensure KBs are configured based on the specific needs of each organization.



The widespread misconfiguration of ServiceNow instances has led to the exposure of sensitive Knowledge Base data, posing a significant security risk to enterprises. While ServiceNow has made efforts to improve security through ACL updates and proactive customer support, the onus remains on organizations to ensure that their KBs are properly secured. By implementing strict access controls, disabling unnecessary public access, and utilizing ServiceNow’s built-in security features, enterprises can minimize the risk of data exposure and safeguard their critical information.

Organizations using ServiceNow should take immediate steps to audit their Knowledge Base configurations, ensure User Criteria is set correctly, and utilize all available security properties to prevent unauthorized access. Failure to do so could leave valuable corporate information vulnerable to exploitation by malicious actors.







Over 1,000 ServiceNow instances are misconfigured, leading to the unintentional exposure of sensitive corporate Knowledge Base (KB) data

Over 1,000 ServiceNow Instances Found Leaking Corporate Knowledge Base Data



The Federal Communications Commission (FCC) has reached a $13 million settlement with AT&T following an extensive investigation into the telecom giant's handling of customer data, specifically in relation to a vendor's cloud breach that occurred three years ago. This settlement is a direct consequence of findings that revealed significant gaps in AT&T’s data protection measures, raising concerns about the company’s ability to ensure supply chain security and prevent unauthorized access to sensitive customer information.

The Breach: A Timeline of Events

In January 2023, a security breach targeted AT&T's vendor, which was responsible for creating personalized video content, such as billing and marketing materials. This breach exposed the personal data of approximately 9 million AT&T wireless customers. Although critical details such as credit card numbers, Social Security numbers, and account passwords were not compromised, the exposed Customer Proprietary Network Information (CPNI) included first names, wireless account numbers, phone numbers, and email addresses. AT&T promptly notified affected customers, clarifying that the most sensitive personal information remained secure.

The breach was particularly alarming because the vendor had been contractually obligated to destroy or return customer data after the contract ended—years before the actual breach. However, AT&T failed to adequately monitor the vendor's compliance with this obligation, leading to the unauthorized retention and eventual exposure of customer data.

Supply Chain Integrity and Vendor Oversight Failures

The FCC's investigation extended beyond the breach itself, delving into AT&T's broader privacy and cybersecurity practices. Central to the investigation was the issue of supply chain integrity—specifically, whether AT&T maintained sufficient oversight of its vendors' data handling practices. In this case, the vendor’s failure to destroy or return customer data in a timely manner exposed AT&T’s inadequate supervision of third-party compliance with contractual and regulatory obligations.

The FCC's findings underscored the critical need for telecom companies to monitor not only their own data security protocols but also those of their vendors. As FCC Chairwoman Jessica Rosenworcel emphasized, "Carriers must take additional precautions given their access to sensitive information, and we will remain vigilant in ensuring that's the case no matter which provider a customer chooses."

Strengthening Data Governance and Security Measures

In response to the investigation, AT&T has committed to enhancing its data governance framework to prevent future breaches of this nature. Under the terms of the settlement, AT&T will implement a comprehensive Information Security Program designed to bolster customer data protection and ensure compliance with strict data retention and disposal policies.

Key elements of this new Information Security Program include:

Data Inventory Processes: AT&T will improve its ability to track data shared with third-party vendors, ensuring that all customer data is accounted for and adequately protected.

Vendor Compliance: AT&T will ensure that its vendors adhere to strict data retention and disposal policies, thereby reducing the risk of unauthorized data exposure.

Annual Compliance Audits: The company will conduct regular audits to assess its adherence to the new data security requirements, with a focus on minimizing the potential for future breaches.


The FCC's Enforcement: A Message to the Telecom Industry

The FCC's actions send a clear signal to the telecommunications industry regarding the importance of safeguarding consumer data. In a statement, Enforcement Bureau Chief Loyaan A. Egal reiterated that "Communications service providers have an obligation to reduce the attack surface and entry points that threat actors seek to exploit in order to access sensitive customer data." This case serves as a reminder that even if a company's own systems are not directly compromised, it remains accountable for breaches that occur within its supply chain.

The Continuing Fallout: Additional Data Breaches

Unfortunately for AT&T, the January 2023 breach was not an isolated incident. In July 2024, the company reported yet another significant data breach, in which threat actors accessed call logs for approximately 109 million customers. The attackers exploited vulnerabilities in AT&T's Snowflake account, exposing phone numbers, call durations, and communication metadata. However, the content of the calls, customer names, and highly sensitive personal information were not compromised. Despite these assurances, the sheer scale of the breach has raised further concerns about AT&T's ability to secure its customer data.

Additionally, in April 2024, AT&T notified 51 million current and former customers of a data breach that was linked to an earlier hack in March 2023. This breach resulted in a massive leak of customer data, some of which had been offered for sale on the Breached hacking forum as early as 2021. These successive breaches have only intensified scrutiny of AT&T’s cybersecurity posture, pushing the company to take more aggressive steps in securing its data assets.

Conclusion: A New Era of Data Accountability

The $13 million settlement with the FCC marks a pivotal moment in the evolving landscape of data security within the telecommunications sector. For AT&T, the agreement represents a critical step toward rebuilding trust with its customers and ensuring that its vendors adhere to the highest standards of data protection.

As digital threats continue to evolve, telecom providers must remain vigilant in securing not only their own systems but also the entire supply chain. This case serves as a stark reminder that privacy and security responsibilities do not end at a company’s front door—they extend throughout the entire vendor network.

The FCC’s actions underscore the growing importance of regulatory oversight in holding telecom giants accountable for the security of their customers’ data in the digital age, reinforcing the necessity of proactive governance and comprehensive cybersecurity strategies.

AT&T's future success will hinge on its ability to prevent similar incidents from recurring and demonstrate a genuine commitment to safeguarding the privacy and security of its users.

The Cybersecurity and Infrastructure Security Agency (CISA) recently issued a directive to all U.S. federal agencies, urging immediate action to secure systems against a critical Windows vulnerability—CVE-2024-43461. Initially believed to be dormant, this zero-day flaw in the MSHTML component has now been confirmed to have been exploited in active attacks by the Void Banshee Advanced Persistent Threat (APT) group. Microsoft has since updated its advisory to acknowledge that this flaw, in conjunction with another vulnerability (CVE-2024-38112), was exploited in real-world attacks before being patched.

2. Vulnerability Overview: CVE-2024-43461

The vulnerability (CVE-2024-43461) is classified as a spoofing bug within the MSHTML engine, which is used by Internet Explorer and Microsoft Office applications. Exploiting this flaw allows attackers to execute arbitrary code on unpatched Windows systems, typically by luring targets into interacting with a maliciously crafted webpage or file.

The core of the exploit lies in a flaw related to the way Internet Explorer prompts users after a file is downloaded. Attackers can craft a file with a hidden true file extension, misleading users into believing they are interacting with a benign document. This social engineering vector has become a hallmark of phishing campaigns and malware deployment strategies targeting vulnerable systems.

3. Attack Chain and Exploitation

Void Banshee, a known APT group targeting organizations across North America, Europe, and Southeast Asia, exploited this vulnerability as part of a larger exploit chain that involved CVE-2024-38112. This attack chain was leveraged to deliver information-stealing malware, specifically the Atlantida malware, known for harvesting sensitive data such as passwords, authentication cookies, and cryptocurrency wallets from infected devices.

The attack works by using malicious HTA (HTML Application) files disguised as PDF documents. The attackers used braille whitespace characters (encoded as %E2%A0%80) to push the .hta file extension out of view, tricking the victim into believing the file was a harmless document.

Detailed Exploit Flow:

1. File Download Mechanism: The MSHTML engine fails to display the true file extension, allowing the crafted filename to appear benign (e.g., a .pdf file).


2. Execution Trigger: The user is prompted to open what they believe is a legitimate document. Upon execution, the system is compromised, and malicious code is run in the context of the current user.


3. Payload Delivery: Once executed, the HTA file initiates the download and installation of the Atlantida malware, which starts harvesting sensitive information from the victim's device.



4. Impact and Scope

Void Banshee’s exploitation of this vulnerability has particularly severe implications for both public and private sector organizations. Once infected, affected systems can be used for:

Data theft: Targeting sensitive user information such as login credentials, authentication cookies, and cryptocurrency wallets.

Credential harvesting: The use of harvested data for lateral movement within networks.

Financial gain: Many of the campaigns orchestrated by Void Banshee are financially motivated, focusing on high-value targets across various industries.


CISA's directive underscores the critical nature of this vulnerability, classifying it as a high-priority exploit that must be patched immediately to prevent further breaches.

5. Mitigation and Patching

Microsoft addressed this flaw with patches released during the July 2024 and September 2024 Patch Tuesdays. Initially, only CVE-2024-38112 was patched in July 2024, which disrupted part of the attack chain. However, a full remediation for CVE-2024-43461 required the additional September patch.

Required Actions:

Install July 2024 and September 2024 patches: Microsoft has issued security updates that address both vulnerabilities in the exploit chain. Ensuring both patches are installed is essential to fully protect affected systems.

Awareness and Training: Organizations should educate employees on the dangers of opening files from untrusted sources and emphasize scrutiny of file extensions in downloaded content.


6. Federal Agencies Directive: CISA’s Mandate

In response to the growing threat, CISA has added CVE-2024-43461 to its Known Exploited Vulnerabilities (KEV) Catalog. Under Binding Operational Directive (BOD) 22-01, federal agencies are mandated to secure their systems against this vulnerability by October 7, 2024. This directive emphasizes the importance of promptly applying patches and securing systems from such high-severity exploits.

While this directive is aimed at federal agencies, it also serves as a warning to private organizations globally. Given the widespread use of Windows and the critical nature of this exploit, it is advisable for all organizations to prioritize patching and deploy protective measures against this threat.

7. Threat Actor Profile: Void Banshee APT Group

Void Banshee is a financially motivated APT group known for sophisticated cyber-espionage operations. The group has been active in targeting high-value sectors across multiple regions, including North America, Europe, and Southeast Asia. Void Banshee is notorious for employing advanced techniques such as zero-day exploits, malware obfuscation, and data exfiltration strategies aimed at maximizing financial gain through unauthorized access and theft of sensitive data.

Objectives of Void Banshee:

Financial exploitation: Primarily focused on data theft that can be monetized, such as login credentials and cryptocurrency wallets.

TrickMo Evolves: From Banking Trojan to Data-Stealing Malware

In early September 2024, Kawasaki Motors Europe (KME) was the target of a sophisticated cyberattack solely orchestrated by the RansomHub ransomware gang. 

While the initial infiltration attempt was unsuccessful, the incident triggered a swift response involving temporary server isolation and a comprehensive data recovery strategy. 

With RansomHub threatening to leak 487 GB of stolen data, Kawasaki’s fight against this intrusion continues to be disclosed, highlighting the ever-evolving tactics of ransomware groups.

### Anatomy of Kawasaki Motors Europe (KME) Cyberattack


Kawasaki's response to the cyberattack was marked by a strategic isolation of its servers across Europe. 
As part of this proactive defensive strategy the automotive company initiated a remedial process to remove any lingering malware as we speak. 

According to [Kawasaki](https://www.kawasaki.eu/en/News_and_events/kawasaki-european-HQ-recovers-from-cyber-attack.html), while the cyberattack resulted in temporary disruptions, its business operations, including dealerships, suppliers, and logistics, remained largely unaffected.

### KME’s Multi-layered Incident Response Strategy

1️⃣ **Server Isolation:** Kawasaki immediately isolated its servers to prevent further propagation of malware across its infrastructure.


2️⃣ **Collaborative Analysis:** Kawasaki's internal IT teams worked hand in hand alongside the external cybersecurity team, ensuring each server was thoroughly scanned before reconnecting to the corporate network.


3️⃣ **Malware Remediation:** The company's efforts centered on identifying and neutralizing any suspicious material that could compromise the integrity of its systems.

By the end of the recovery phase, 90% of the company’s servers were expected to be operational again, underscoring the resilience of Kawasaki’s disaster recovery protocols.

### RansomHub’s Bold Move—Claiming Responsibility

The RansomHub ransomware group, infamous for its ransomware-as-a-service (RaaS) model, claimed responsibility for the attack on September 5, 2024. 

As part of their extortion efforts, the group added Kawasaki to its dark web extortion portal, threatening to release 487 GB of stolen data if the demands were not met.

### Dissecting RansomHub’s Threat Model

RansomHub’s approach is consistent with modern double extortion tactics—encrypting the victim’s data while simultaneously threatening to release sensitive information unless a ransom is paid. 

Their success can be attributed to the influx of affiliates from the now-defunct [BlackCat/ALPHV](https://www.secureblink.com/cyber-security-news/blackmatter-affiliates-actively-circulating-blackcat-raas-without-getting-rebranded) ransomware operation, who brought with them a wealth of expertise in executing high-profile cyberattacks.

Adobe has patched a critical zero-day vulnerability in Adobe Acrobat Reader. This flaw, identified as CVE-2024-41869, allows remote code execution when a specially crafted PDF is opened, posing a significant threat to users. 

The vulnerability was disclosed after a proof-of-concept (PoC) exploit surfaced publicly, with researchers urging immediate upgrades to the latest version of Acrobat Reader.

#### Vulnerability Breakdown: CVE-2024-41869

The CVE-2024-41869 vulnerability is a use-after-free (UAF) issue, a common yet dangerous security flaw that arises when a program continues to access a memory location after it has been freed. 

In such cases, the program may exhibit unexpected behavior, such as crashes, but the true danger lies in the potential for an attacker to inject and execute malicious code.

***Here's a breakdown of how this vulnerability works:***

**Use-After-Free (UAF) Vulnerability:** UAF vulnerabilities occur when memory that has already been deallocated is improperly accessed by a program. When exploited, this can lead to system crashes, or worse, the execution of arbitrary code.

**Remote Code Execution (RCE):** Attackers can craft malicious PDF files that trigger the vulnerability in Acrobat Reader. Once the user opens the file, the attacker can remotely execute code on the targeted system, potentially leading to full control of the machine.


The vulnerability is particularly dangerous due to the public availability of a PoC exploit, allowing threat actors to exploit the flaw before a majority of users apply the patch.

#### Discovery of the Vulnerability

The vulnerability was first identified by Haifei Li, a cybersecurity researcher who developed EXPMON, a sandbox-based detection platform designed specifically to detect zero-day exploits. Li's discovery of this vulnerability highlights the importance of detecting exploits from a vulnerability perspective, rather than relying solely on malware detection.

EXPMON is engineered to focus on advanced exploits, addressing a gap in detection systems that only concentrate on malware. 

According to Li, _“exploits operate quite differently from malware,”_ necessitating specialized approaches for early detection of such threats. The vulnerability was discovered in June when a malicious PDF containing a proof-of-concept exploit was submitted to EXPMON for analysis.

Although the PoC did not carry a malicious payload, it successfully demonstrated the potential to exploit the UAF bug, which could be leveraged for remote code execution.

#### Patch Timeline and Challenges

Adobe responded to the initial disclosure by releasing a security update in August 2024. However, this initial patch failed to fully mitigate the vulnerability. Researchers from EXPMON noted that the bug could still be triggered under specific conditions, such as when users closed certain dialogs within the application. 

Despite the update, Acrobat Reader would still crash, indicating that the UAF issue persisted.

EXPMON highlighted the flaw on social media, emphasizing that the vulnerability remained exploitable even after Adobe's first patch attempt.

Finally, in September 2024, Adobe released a second, comprehensive update that fully addressed the vulnerability. 
The CVE-2024-41869 flaw has since been resolved in the latest versions of Adobe Acrobat Reader and Adobe Acrobat.

#### Urgent Action: Update Adobe Acrobat Reader Now

Given the severity of the CVE-2024-41869 vulnerability, it is critical for users to update their Adobe Acrobat Reader to the latest version immediately. With the public PoC exploit in circulation, unpatched systems are vulnerable to targeted attacks.

The vulnerability is now fully patched, and users can download the latest security updates directly from Adobe's security page. 
Failure to apply the update could result in remote attackers executing arbitrary code on vulnerable systems, leading to data theft, system compromise, or further malware infections.

Thanks to the work of researchers like Haifei Li and tools like EXPMON, critical vulnerabilities such as CVE-2024-41869 can be identified and mitigated before widespread exploitation occurs. Nonetheless, timely patching remains a crucial defense against such threats.

As more technical details about the vulnerability and its detection are expected to be published by Li and the EXPMON team, the case of CVE-2024-41869 serves as a reminder of the evolving complexity of exploit detection and the need for proactive security measures.

CosmicBeetle, a notorious threat actor active since at least 2020, has continued its aggressive cybercriminal activities into 2024, deploying its evolving ScRansom ransomware to exploit SMBs (Small and Medium Businesses) across Europe and Asia. While not the most sophisticated ransomware, ScRansom has proven dangerous due to CosmicBeetle's adaptability and persistence. 

The ScRansom ransomware, which replaced the previously deployed Scarab ransomware, has undergone continual development since its first appearance in 2023. Despite its imperfections and limitations, the ransomware's use of experimental features and connections to other notorious ransomware gangs makes it a formidable threat. Recently, there has been evidence that CosmicBeetle has formed an affiliation with RansomHub, a fast-growing ransomware-as-a-service (RaaS) gang, further boosting its capabilities.

#### CosmicBeetle's Evolution and Affiliation with RansomHub

##### CosmicBeetle’s Transition from Scarab to ScRansom

ScRansom marked a significant transition for CosmicBeetle. Originally relying on Scarab ransomware, the group shifted its focus in 2023 to its custom-built ransomware, ScRansom. ESET researchers believe with high confidence that ScRansom is now CosmicBeetle’s ransomware of choice. Despite this shift, the group continues to face challenges, from poorly executed encryption schemes to imperfect decryption processes, indicating their relatively immature status in the world of cybercrime.

##### Impersonation of LockBit and Affiliation with RansomHub

CosmicBeetle has engaged in a tactic known as "brand hijacking," leveraging the reputation of the infamous LockBit ransomware gang. By impersonating LockBit through ransom notes and using leaked LockBit builders, CosmicBeetle sought to intimidate victims into paying ransom demands. However, its most recent and significant move has been its affiliation with RansomHub.

RansomHub, a RaaS group that emerged in early 2024, has quickly gained prominence, and researchers believe that CosmicBeetle has now become one of its affiliates. The rapid rise of RansomHub and its association with notorious actors like CosmicBeetle adds a layer of complexity and danger to the group’s activities. The following sections delve deeper into the significance of RansomHub in this context.

#### The Rise of RansomHub: A New Player in the RaaS Ecosystem

##### What Is RansomHub?

RansomHub is a relatively new ransomware-as-a-service (RaaS) platform that has emerged as a significant player in the cybercrime ecosystem. First spotted in March 2024, RansomHub has attracted attention for its rapid rise and involvement with some of the more notorious threat actors. As an affiliate-based platform, RansomHub provides ransomware to various groups in exchange for a share of the ransom payments.

##### How RansomHub Operates

RansomHub operates by providing ransomware tools to affiliates who then deploy the ransomware to their own targets. This model allows for a decentralized approach to ransomware deployment, making it more challenging for law enforcement and cybersecurity professionals to track the origin of attacks. Affiliates, like CosmicBeetle, gain access to sophisticated ransomware builders and decryption tools, enabling them to conduct attacks with relative ease.

#### Technical Analysis of ScRansom

##### ScRansom’s Encryption Mechanism

ScRansom employs a range of encryption mechanisms that are continually evolving. Initially, the ransomware used simple AES-CTR-128 encryption but has since moved to a more complex, albeit flawed, system. The latest versions of ScRansom generate unique encryption keys for each file, making recovery difficult without paying the ransom.

One key aspect of ScRansom's encryption scheme is its partial encryption mode. The ransomware targets specific portions of files, reducing the encryption time but increasing the difficulty of decryption without the appropriate keys. Victims who attempt to decrypt their files without the proper tools risk permanently losing data, especially when ScRansom’s ERASE mode is applied, which irreversibly corrupts files.

##### Decryption Challenges

Victims face significant challenges when attempting to decrypt their files, even after paying the ransom. ScRansom often requires multiple decryption keys for a single machine, complicating the process. Moreover, due to CosmicBeetle’s immature decryption mechanisms, some files may be permanently lost even after successful decryption. This is further complicated by ScRansom’s incomplete decryption process, where victims may need to manually enter different keys and run the decryption tool multiple times.

#### CosmicBeetle’s Exploitation Tactics

##### Vulnerability Exploitation

CosmicBeetle is known for exploiting years-old vulnerabilities in public-facing applications. Some of the common vulnerabilities exploited include:
- **CVE-2017-0144 (EternalBlue)**: Used to exploit outdated SMB protocols.
- **CVE-2023-27532**: A vulnerability in Veeam Backup & Replication components.
- **CVE-2021-42278 and CVE-2021-42287**: AD privilege escalation vulnerabilities exploited through the noPac attack chain.
- **CVE-2022-42475**: A vulnerability in FortiOS SSL-VPN, enabling remote access.
- **CVE-2020-1472 (Zerologon)**: A critical privilege escalation vulnerability in Microsoft Active Directory.

##### Targeting SMBs

CosmicBeetle primarily targets SMBs across various industries, including manufacturing, pharmaceuticals, legal, education, and healthcare. SMBs are often vulnerable due to insufficient patch management practices and reliance on older systems, making them ideal targets for exploitation. The industries targeted by CosmicBeetle reflect the group’s opportunistic approach, prioritizing ease of exploitation over high-value targets.

#### CosmicBeetle’s Use of Brute-Force Attacks and Tools

Aside from exploiting vulnerabilities, CosmicBeetle frequently relies on brute-force methods to gain initial access to victim networks. This includes targeting Remote Desktop Protocol (RDP) services and SMB ports that are exposed to the internet. CosmicBeetle’s toolkit also includes custom-built tools like ScHackTool, ScInstaller, and ScPatcher, which are used to escalate privileges and deploy ransomware once inside the victim’s network.

#### RansomHub’s Growing Influence in the RaaS Market

##### Why RansomHub Matters

The rise of RansomHub marks a shift in the ransomware ecosystem, providing newer ransomware groups with the tools and infrastructure they need to compete with more established gangs like LockBit and BlackCat. The RaaS model allows even relatively inexperienced threat actors to launch sophisticated attacks, leveraging the tools and knowledge provided by more established cybercriminal organizations.

##### RansomHub’s Role in CosmicBeetle’s Success

RansomHub has been instrumental in CosmicBeetle’s continued success, providing access to advanced ransomware tools that have allowed CosmicBeetle to refine its attacks. The affiliation between the two groups likely provides CosmicBeetle with additional resources, enabling them to improve ScRansom and expand their operations to new regions and industries.



For victims of ScRansom, the challenges are significant. The complex and flawed encryption mechanism, coupled with the involvement of a RaaS platform like RansomHub, makes decryption difficult and costly. As RansomHub continues to grow in influence, organizations must remain vigilant, ensuring that they have robust cybersecurity measures in place to mitigate the risks posed by this dangerous new threat actor.



CosmicBeetle just raised the stakes—teaming up with RansomHub to unleash a rapidly evolving ransomware: ScRansom.

In August 2024, Avis, a leading car rental company, fell victim to a significant cyberattack that compromised the personal data of nearly 300,000 customers. This breach, affecting sensitive information such as credit card details and driver's license numbers, underscores persistent gaps in corporate cybersecurity practices. 
## **Timeline**  
The cyberattack was detected on August 5, two days after unauthorized access to one of Avis' business applications began. The company’s data breach notice, filed with various U.S. state attorneys general, reveals that customer names, email addresses, mailing addresses, phone numbers, dates of birth, credit card numbers (with expiration dates), and driver’s license numbers were stolen. Texas, with 34,592 affected residents, was hit particularly hard. The breach is expected to affect more individuals as further filings surface in the coming weeks.

## **Analyzing the Nature of the Breach**  
While the technical specifics of the breach remain undisclosed, questions arise about how Avis stored such sensitive data and what security protocols were in place—or absent—that allowed such information to be compromised. 
The fact that both personal identifiers and financial data were exposed suggests potential failures in encryption, data segregation, or multi-layered defenses. The absence of a swift response also hints at potential shortcomings in intrusion detection systems (IDS) and incident response protocols.

## **Avis’ Response: A Case of Corporate Silence?**  
Despite the gravity of the breach, Avis has remained relatively quiet about the attack. The company did not respond to requests for further comment, raising concerns about transparency in the face of a significant cyber incident. This silence may reflect a strategic decision to contain reputational damage, but it also leaves consumers and cybersecurity experts in the dark about the true extent of the damage.

With businesses increasingly collecting vast amounts of personal data, the responsibility to protect this information is paramount. 
Avis, a global company with over 10,000 rental locations and $12 billion in revenue, should have had the resources to maintain robust cybersecurity defenses. 
The fact that a breach of this magnitude occurred suggests systemic vulnerabilities that could extend beyond Avis and into the wider industry.

## **Impact on Consumers and Regulatory Implications**  
The stolen data exposes customers to financial fraud, identity theft, and privacy violations. Given the nature of the compromised data, the affected individuals may face long-term consequences. 
This breach will likely fuel ongoing discussions about stronger regulatory frameworks, particularly in the U.S., where data protection laws like the California Consumer Privacy Act (CCPA) and General Data Protection Regulation (GDPR) in Europe demand stricter compliance.

**Cisco Closes Critical Backdoor in Smart Licensing Utility Amid Broader Security Patch Rollout**

Cisco has patched a critical vulnerability in the Cisco Smart Licensing Utility (CSLU), eradicating a dangerous backdoor account that allowed unauthorized access to administrative systems. This vulnerability, tracked as CVE-2024-20439, enabled attackers to gain administrative privileges via an "undocumented static user credential," posing a severe threat to unpatched systems. The potential for exploitation was vast, with attackers able to infiltrate systems and take control over the application programming interface (API) of the Smart Licensing Utility, which is critical for managing licenses and associated products on-premise.

The CLSU, a pivotal Windows-based application, is often deployed by organizations to maintain an offline licensing environment, distinct from Cisco's cloud-based Smart Software Manager. However, the very architecture that made it convenient for offline operations became a liability, as the unpatched systems were left vulnerable to remote exploits. The exploit, which did not require authentication, could have facilitated full administrative control over the impacted systems. A successful breach would allow attackers to manipulate licensing functions or, worse, pivot to other critical infrastructures.

Alongside this alarming backdoor account, Cisco patched another high-severity vulnerability (CVE-2024-20440) within the CLSU. This flaw allowed threat actors to send crafted HTTP requests to gain access to log files containing sensitive information, including API credentials. The security implications of such an exploit are profound, as it could lead to further compromises, including lateral movement within affected networks.

It's important to note that both vulnerabilities only affect specific versions of the Cisco Smart Licensing Utility, particularly those from releases 2.0.0 to 2.2.0. Systems running release 2.3.0 and beyond are secure, as Cisco has fully resolved the issues in these versions. Cisco's Product Security Incident Response Team (PSIRT) has not yet discovered any evidence that these vulnerabilities have been exploited in the wild. Nonetheless, the potential threat was significant, prompting an urgent call for users to patch their systems.

These security flaws follow a concerning trend within Cisco's product portfolio. The company has a history of backdoor account discoveries across various platforms, including its Digital Network Architecture (DNA) Center, IOS XE, and Wide Area Application Services (WAAS) software. Each of these backdoor credentials has posed severe security risks, raising questions about the underlying security protocols within Cisco's product development lifecycle.

Further exacerbating Cisco's security challenges, the company also had to respond to a maximum severity vulnerability (CVE-2024-20419) in its Cisco Smart Software Manager On-Prem (SSM On-Prem). This flaw allowed attackers to change any user password on unpatched license servers, providing a convenient gateway for credential abuse and system hijacking. Just weeks after its disclosure, exploit code was published online, urging Cisco to warn administrators about the necessity of immediate patches to avoid catastrophic breaches.

In an unsettling series of events earlier this year, Cisco faced a zero-day vulnerability (CVE-2024-20399) affecting its NX-OS operating system, which had been actively exploited since April. Hackers utilized this flaw to install malware on vulnerable MDS and Nexus switches, amplifying concerns about the security resilience of Cisco's networking devices. In conjunction with these incidents, Cisco reported that state-backed hackers, notably UAT4356 and STORM-1849, had exploited two additional zero-day bugs (CVE-2024-20353 and CVE-2024-20359) to infiltrate government networks globally.

With this latest patch release, Cisco has taken significant strides to address its mounting security vulnerabilities. However, the frequency of these discoveries underscores the persistent need for enterprises to remain vigilant in applying updates, patching systems, and safeguarding against potential exploits. The interconnectedness of Cisco's products across the global network infrastructure means that every unpatched vulnerability poses a substantial risk, not just to individual organizations but to the broader cybersecurity landscape.

For enterprises relying on Cisco's Smart Licensing Utility, prompt migration to a fixed release is imperative to ensure protection. Versions 2.0.0 through 2.2.0 should be upgraded immediately, as Cisco continues to emphasize the importance of keeping systems secure from known threats.

Cisco resolves critical backdoor vulnerability in Smart Licensing Utility, patching security flaws that allow remote admin access to unpatched systems.

Data Swiped Out, Oil Giants in Chaos After RansomHub Hijacks Halliburton


GitHub, a widely used platform for hosting and collaborating on software projects, is being exploited to distribute the Lumma Stealer, a sophisticated information-stealing malware, under the guise of fake fixes in project comments. This malicious campaign targets developers and contributors by luring them into downloading and executing harmful files disguised as legitimate solutions to technical issues.

**Campaign Discovery:**
The malicious activity was first reported by a contributor to the Teloxide Rust library, who shared their experience on Reddit after receiving multiple comments on their GitHub issues. These comments purported to offer fixes but instead contained links to malware. Subsequent investigations revealed that this was not an isolated incident; thousands of similar comments were found across numerous GitHub repositories, all aiming to trick users into downloading malware.

**Modus Operandi:**
The attackers craft comments that appear to be genuine responses to issues raised on GitHub. These comments typically direct users to download a password-protected archive from a file-sharing service like MediaFire or a shortened URL via Bit.ly. The archive, deceptively named something innocuous like "fix.zip," contains a few DLL files and an executable named `x86_64-w64-ranlib.exe`.

Upon running this executable, the Lumma Stealer malware is deployed on the victim's system. Lumma Stealer is an advanced information stealer that targets a wide range of sensitive data, including:

- **Browser Data:** Steals cookies, credentials, passwords, credit card information, and browsing history from popular browsers such as Google Chrome, Microsoft Edge, Mozilla Firefox, and other Chromium-based browsers.
- **Cryptocurrency Wallets:** Exfiltrates cryptocurrency wallets and private keys, specifically targeting files with names like `seed.txt`, `pass.txt`, `ledger.txt`, `trezor.txt`, `metamask.txt`, `bitcoin.txt`, `words.txt`, `wallet.txt`, `*.txt`, and `*.pdf`.
- **Sensitive Files:** Searches for and steals text files likely to contain private crypto keys and passwords.

The stolen data is then compiled into an archive and exfiltrated to the attacker's server. This data can be exploited in further attacks or sold on underground cybercrime marketplaces.

**Scope of the Attack:**
Reverse engineer Nicholas Sherlock informed BleepingComputer that over 29,000 comments distributing this malware were posted within a span of just three days. This widespread campaign indicates a high level of automation and suggests that the attackers are likely using scripts or bots to distribute the comments at scale.

**GitHub’s Response:**
GitHub's security team has been actively removing these malicious comments as they are identified. However, the scale of the attack and the persistence of the threat actors present significant challenges. Despite these efforts, some users have already fallen victim to the scam, unknowingly compromising their systems.

**Mitigation and Recommendations:**
For those who have inadvertently executed the malware, immediate action is crucial:

1. **Change Passwords:** Immediately change passwords for all accounts, ensuring that each account uses a unique, strong password. Consider using a password manager to generate and store complex passwords.
2. **Migrate Cryptocurrency:** If cryptocurrency wallets or private keys were stored on the compromised system, transfer your funds to a new wallet. Ensure that the new wallet is secured and that private keys are stored safely offline.
3. **System Scan:** Run a full system scan with a reputable anti-malware tool to detect and remove any traces of Lumma Stealer or other malware that may have been installed.
4. **Monitor Accounts:** Keep a close eye on financial and online accounts for any unauthorized activity. Consider enabling multi-factor authentication (MFA) wherever possible to add an additional layer of security.

**Broader Implications:**
The Lumma Stealer campaign is part of a broader trend of increasing cyber threats targeting software developers and platforms like GitHub. The attackers exploit the trust inherent in open-source communities, where users often share code and solutions freely, to disseminate malware.

Last month, Check Point Research disclosed a similar campaign orchestrated by the Stargazer Goblin threat group. This group used a malware Distribution-as-a-Service (DaaS) model to distribute information-stealing malware via over 3,000 fake GitHub accounts. While it remains unclear if the current Lumma Stealer campaign is connected to the Stargazer Goblin group, the tactics bear striking similarities, suggesting that GitHub may be an ongoing target for various threat actors.

Atlassian CVE-2023-22527 Cryptojacking Full-Scale Exploitation

The RansomHub ransomware gang has been identified as the attackers behind the recent cyberattack on [Halliburton](https://www.secureblink.com/cyber-security-news/halliburton-s-global-business-operations-crippled-by-major-cyberattack), a leading oil and gas services giant. 

This attack, which occurred on August 21, 2024, has significantly disrupted Halliburton's IT systems and business operations, impacting the company's ability to generate invoices, process purchase orders, and maintain overall business continuity.

#### Impact on Operations

Halliburton disclosed the breach in an SEC filing last Friday, [acknowledging](http://www.sec.gov/ix?doc=/Archives/edgar/data/45012/000004501224000049/hal-20240821.htm) that an unauthorized party gained access to certain systems. 

This breach has caused widespread operational disruption, with customers reporting an inability to perform essential business functions due to the system outages.

The company stated in the SEC filing: _"On August 21, 2024, Halliburton Company (the 'Company') became aware that an unauthorized third party gained access to certain of its systems."_ 

Halliburton quickly activated its quick action response plan, involving both internal and external cybersecurity experts to assess and mitigate the unauthorized activity.

#### Customer Concerns and Industry Response

Despite the significant impact of the attack, Halliburton has provided limited details to its customers, leaving many in the oil and gas industry uncertain about the potential risks to their own systems. 
This lack of transparency has led some customers to disconnect from Halliburton's services as a precautionary measure.

Several companies affected by the attack are working with the Oil and Natural Gas Information Sharing and Analysis Center (ONG-ISAC), which coordinates physical and cybersecurity threat responses for the oil and gas sector. These companies are seeking technical information to assess whether they, too, have been breached.

#### RansomHub Ransomware Identified

Rumors of RansomHub's involvement in the Halliburton attack had actively circulated for days before the company confirmed the connection. 

Discussions on platforms such as Reddit and TheLayoff hinted at RansomHub's involvement, and a partial ransom note was even published on the latter site. 

However, when attempting to contact Halliburton for confirmation, the company declined to provide additional comments, stating, _"We are not commenting beyond what was included in our filing. Any subsequent communications will be in the form of an 8-K."_

In an email dated August 26, 2024, sent to suppliers, Halliburton furnishes further details. 

The company mentioned taking certain systems offline to protect them and confirmed that it is working with cybersecurity firm Mandiant to investigate the incident. 

Halliburton also assured stakeholders that its email systems remain operational, as they are hosted on Microsoft Azure infrastructure. 

Meanwhile, RansomHub has already been in surfacing with because of there new adoption to [EDRKillShifter](https://www.secureblink.com/cyber-security-news/edr-kill-shifter-a-new-edr-killing-malware-weapon-for-ransomware-operators).

To assist customers, the email included a list of Indicators of Compromise (IOCs) related to the attack, such as file names and IP addresses.

One notable IOC was a Windows executable named `maintenance.exe`, identified as a RansomHub ransomware encryptor. 

Further analysis revealed that this encryptor appears to be a newer version, featuring a command-line argument `-cmd string` that executes a command on the device before file encryption.

#### RansomHub Ransomware Operation

RansomHub, which launched in February 2024, initially claimed to be a data theft and extortion group, selling stolen files to the highest bidder. 

However, it quickly became evident that RansomHub also employed ransomware encryptors in its double-extortion attacks. In these attacks, the threat actors breach networks, steal data, and then encrypt the files. 

The combination of encrypted files and the threat of leaking stolen data is used to coerce victims into paying a ransom.

Symantec's analysis of the RansomHub encryptors indicated that they are based on the Knight ransomware encryptors, formerly known as Cyclops. Interestingly, the Knight operation claimed to have sold its source code in February 2024, coinciding with RansomHub's emergence. 

This has led many cybersecurity researchers to believe that RansomHub is a rebranded version of the Knight ransomware operation.

#### FBI Involvement 

On the same day as Halliburton's disclosure, the FBI released an advisory on RansomHub, detailing the threat actor's tactics and warning that the group has breached at least 210 victims since its inception. 

The timing of the advisory suggests a coordinated effort to address the growing threat posed by RansomHub, especially in the wake of the Halliburton attack.

RansomHub has been responsible for several high-profile attacks in 2024, including those on Patelco Credit Union, Rite Aid, Christie's auction house, and Frontier Communications. 

The group also used its data leak site to publish stolen data from Change Healthcare after the [shutdown of the BlackCat](https://www.secureblink.com/cyber-security-news/royal-ransomware-group-adds-black-suit-encryptor) and ALPHV ransomware operations which includes victims like [Prudential](https://www.secureblink.com/cyber-security-news/2-5-m-exposed-alphv-ransomware-involved-prudential-data-breach), [VFCorporation](https://www.secureblink.com/cyber-security-news/35-5-million-vf-corp-user-data-stolen-in-alphv-ransomware-attack), [Creos](https://www.secureblink.com/cyber-security-news/creos-luxembourg-s-a-attack-was-claimed-by-alphv-aka-black-cat), [BamdiNemco](https://www.secureblink.com/cyber-security-news/black-cat-ransomware-aka-alph-v-claimed-to-have-breached-bandai-namco) and more.

It is believed that after BlackCat's demise, some of its affiliates joined RansomHub, bolstering its capabilities and allowing it to escalate its attacks.

210+ Victims in Halliburton Cyberattack Linked to RansomHub Ransomware


In the ever-evolving landscape of cybersecurity, few names evoke as much intrigue and concern as **Cozy Bear**. Also known as **APT29**, this Russian state-sponsored hacking group has been linked to numerous high-profile cyber espionage campaigns. One of their most recent and sophisticated operations involves a series of **watering hole attacks** targeting Mongolian government websites. This technical write-up delves into the intricacies of these attacks, the methods employed by Cozy Bear, and the broader implications for global cybersecurity.

#### Background on Cozy Bear

Cozy Bear, formally known as **Advanced Persistent Threat 29 (APT29)**, is believed to be tied to Russia's **Federal Security Service (FSB)** and **Foreign Intelligence Service (SVR)**¹². The group has a long history of cyber espionage, targeting governmental and non-governmental organizations worldwide. Notable past operations include the hacks of the **White House**, **Joint Chiefs of Staff**, and the **State Department**¹.

#### Watering Hole Attacks

A **watering hole attack** involves compromising legitimate websites that are frequently visited by the target audience. The attackers embed malicious code into these sites, which then exploits vulnerabilities in the visitors' devices to deliver malware or steal sensitive information.

##### Mongolian Campaign

Between **November 2023 and July 2024**, Cozy Bear orchestrated a series of watering hole attacks on Mongolian government websites⁶. The campaign targeted both **iOS** and **Android** users, leveraging n-day exploits for which patches were available but not yet widely applied.

- **iOS Exploits**: The attackers used an iOS WebKit exploit affecting versions older than 16.6.1. The payload included a cookie stealer framework and a reconnaissance payload to identify vulnerable devices⁶.
- **Android Exploits**: For Android users, the campaign utilized a Chrome exploit chain against versions from m121 to m123. The final payload collected sensitive user data, including cookies, account information, and browsing history⁶.

#### Techniques and Tools
Cozy Bear's methods in these attacks closely mirrored those used by commercial surveillance vendors like **Intellexa** and **NSO Group**. The group harnessed exploits that were identical or strikingly similar to those previously used by these vendors⁵. This raises questions about whether Cozy Bear directly interacted with these companies or independently adopted their techniques.

Cozy Bear's toolset features an array of malware and trojans to infiltrate its targets, all likely designed by the group¹⁴. The malware exfiltrates data to a command and control server, and the attackers may tailor the malware to the environment¹². The backdoor components of Cozy Bear's malware are updated over time with modifications to cryptography, trojan functionality, and anti-detection¹².

#### Broader Implications

The use of commercial spyware techniques by state-sponsored actors like Cozy Bear highlights the proliferation of sophisticated hacking methods beyond their original contexts. This trend underscores the need for device makers to roll out patches for serious vulnerabilities as soon as possible⁵.

#### Related Incidents and Analysis

How Russian Hackers Leveraged Spyware Exploits from NSO Group and Intellexa in Watering Hole Attacks

Young Consulting, now operating under the name Connexure, recently detected a data breach affecting 954,177 individuals following a ransomware attack executed by the notorious BlackSuit group on April 10, 2024. 
The Atlanta-based software [solutions provider](https://connexure.co/about-us/), specializing in employer stop-loss insurance, assists insurance carriers, brokers, and third-party administrators in managing and underwriting stop-loss policies.

The breach was initially discovered on April 13, 2024, when Young Consulting's systems were encrypted by the attackers. Following a comprehensive investigation completed on June 28, 2024, it was [confirmed](https://youngconsulting.com/notice/youngconsulting-notice.html) that sensitive information, including full names, Social Security numbers (SSNs), dates of birth, and insurance claim data, had been compromised.

### Impacted Individuals Urged to Act Promptly

In response to the breach, Young Consulting is offering affected individuals a 12-month complimentary credit monitoring service through [Cyberscout](https://www.icmif.org/supporting_members/cyberscout/). It is crucial for those impacted to enroll in this service before the November 2024 deadline, as BlackSuit has already leaked the stolen data on its darknet-based extortion portal.

Affected parties should remain vigilant for phishing attempts, unsolicited communications, and fraudulent schemes. The attackers began leaking data in May 2024, after Young Consulting presumably refused to comply with ransom demands. Among the leaked data, BlackSuit claims to have disclosed not only the personal details mentioned in the breach notifications but also sensitive business-related information, including contracts, financial reports, and even employee passports.

### BlackSuit's Continued Threat and Broader Implications

The BlackSuit ransomware group, believed to be a rebrand of the infamous [Royal ransomware](https://www.secureblink.com/cyber-security-news/royal-ransomware-group-adds-black-suit-encryptor), has been particularly active in 2024, causing widespread disruption and financial damage. 

Notably, BlackSuit's attack on [CDK Global](https://www.secureblink.com/cyber-security-news/from-royal-to-black-suit-how-rebranded-ransomware-crippled-cdk-global) earlier this year led to significant operational outages and financial loss. 

According to a joint report by CISA and the FBI, BlackSuit has extorted over $500 million from its victims in the past two years.

Security professionals must prioritize the implementation of advanced threat detection and response systems to mitigate the risks posed by sophisticated ransomware groups like BlackSuit.

### Technical Insights and Preventive Measures

For security professionals and technical stakeholders, understanding the technicalities behind such attacks is vital. BlackSuit is known for leveraging advanced encryption algorithms, often AES-256, to lock down critical systems. 

Once access is gained, the group typically exfiltrates large volumes of data before initiating the encryption process, ensuring maximum leverage over their victims.

To prevent such breaches, organizations should adopt a zero-trust architecture, ensuring that all internal and external communications are subject to strict authentication and verification processes. 

Regularly updated intrusion detection systems (IDS) and endpoint detection and response (EDR) tools can also play a critical role in identifying and neutralizing threats before they escalate.

Moreover, regular security audits and employee training programs focused on recognizing phishing attempts and other social engineering tactics can significantly reduce the risk of successful ransomware attacks.

Google Chrome Patches Tenth Zero-Day of 2024 Exploited in the Wild

Houston-based oilfield services giant Halliburton, known for its extensive involvement in the energy sector and its pivotal role in the Deepwater Horizon oil spill, has recently come under scrutiny following a significant cyberattack. The incident, which occurred earlier this week, has led to the shutdown of several internal systems as the company strives to contain the breach and mitigate potential impacts on its operations.

#### Cyberattack Overview and Response

On Wednesday, Halliburton discovered unauthorized access to its systems, prompting an immediate and proactive response to take certain systems offline. The company's swift action reflects standard cybersecurity practices aimed at preventing intruders from maintaining or expanding their access within compromised systems. According to a [statement](https://www.sec.gov/Archives/edgar/data/45012/000004501224000049/hal-20240821.htm) filed with government regulators on Thursday, [Halliburton](https://www.halliburton.com/en/about-us/press-release/halliburton-announces-fourth-quarter-2023-results-increases-dividend) is currently assessing the extent of the incident with the help of _"leading external experts"_ and has yet to disclose specific details regarding the nature of the breach or its impact on operations.

A spokesperson for Halliburton, Victoria Ingalls, has remained tight-lipped, declining to elaborate beyond the official filing. This has raised concerns, particularly after TechCrunch [reported](https://techcrunch.com/2024/08/23/halliburton-shuts-down-systems-after-cyberattack/) a potential security vulnerability in Halliburton's single-sign-on provider, which could allow unauthorized access to internal systems. Despite inquiries from the media, Halliburton has not confirmed whether it was aware of this vulnerability prior to the attack.

#### Impact on Business Operations and Industry Implications

The cyberattack has notably disrupted business operations at Halliburton's north Houston campus and affected global connectivity networks, as reported by a person familiar with the matter. The company has instructed some staff members to avoid connecting to internal networks as a precautionary measure.

The energy sector has increasingly become a viable target for cybercriminals, with high-profile ransomware attacks, such as the [Colonial Pipeline incident in 2021](https://www.secureblink.com/cyber-security-news/colonial-pipeline-hit-by-a-darkside-ransomware-attack-encrypting-entire-system-to-offline), highlighting the vulnerabilities within the industry. 

These attacks can lead to severe operational disruptions, financial losses, and even national security concerns. In Halliburton's case, the full extent of the damage remains unclear, but the potential for significant business and economic implications looms large.

Halliburton's Global Business Operations Crippled by Major Cyberattack 

Phishing attacks have evolved exponentially, with threat actors rigorously leveraging advanced technologies like Progressive Web Applications (PWAs) and WebAPKs. These tools allow attackers to bypass traditional security warnings, making phishing campaigns more effective. This write-up provides an in-depth technical analysis of how PWAs and WebAPKs are being used in phishing attacks, examines the underlying mechanisms, and discusses the broader implications for mobile and user security.

### **1. Technical Overview of PWAs and WebAPKs**

#### **What are PWAs and WebAPKs?**

Progressive Web Applications (PWAs) are web-based applications that offer a native app-like experience. They are built using standard web technologies like HTML, CSS, and JavaScript but leverage modern APIs to provide enhanced functionalities such as offline access, push notifications, and installation on a device's home screen. WebAPKs, on the other hand, are a packaging format used by the Chrome browser to allow PWAs to appear as native apps on Android devices. This conversion grants PWAs direct access to the Android app ecosystem, making them indistinguishable from other apps to most users.

#### **Exploitation of Browser APIs and Security Mechanisms**

Attackers exploit browser APIs, such as the Service Worker API, to bypass traditional security warnings. The Service Worker API acts as a proxy between the web browser and the network, enabling background processes such as caching and push notifications. By manipulating these APIs, attackers can create malicious PWAs that look legitimate but perform nefarious activities, such as stealing credentials or installing malware.

### **2. In-Depth Analysis of Phishing Mechanisms Using PWAs and WebAPKs**

#### **Phishing Tactics and Psychological Manipulation**

Phishing campaigns leveraging PWAs and WebAPKs employ various tactics, including **malvertising**, **smishing** (SMS phishing), and **automated voice calls** (vishing). Each tactic involves different psychological manipulation strategies to trick users into divulging sensitive information or downloading malicious applications.

- **Malvertising**: Threat actors use online advertisements to distribute malicious PWAs. These ads often lead to seemingly benign websites that prompt users to install a PWA, which appears as a native app but is designed to steal data.
- **Smishing and Vishing**: Attackers send text messages or make automated calls with urgent or alarming content, prompting the recipient to take immediate action. This tactic often directs users to phishing websites disguised as legitimate pages, where they are tricked into installing a WebAPK.

**Case Study**: In a recent campaign, attackers used fake COVID-19 alert notifications to direct users to a phishing site that mimicked a government health website. The site prompted users to install a PWA, which then requested permissions to access sensitive device information under the guise of tracking virus exposure.


To rigorously bridge the content gap in the revised technical write-up, I'll enhance each section with a detailed and meticulous analysis, providing more context, technical insights, and explanations to make the write-up richer and more comprehensive. Here's the revised version with detailed additions:


### **Cross-Platform Phishing Tactics**

The phishing websites designed for iOS users employ social engineering tactics to instruct victims to add a Progressive Web Application (PWA) to their home screens. For Android users, the PWA installation process is initiated after they confirm a series of custom pop-up prompts in their browsers. These prompts are carefully crafted to mimic legitimate system notifications, thereby increasing the likelihood of user compliance. 

Once installed, these fraudulent apps are virtually indistinguishable from legitimate banking apps on both platforms, creating a false sense of security. PWAs are essentially web applications that are enhanced to function like standalone native applications, leveraging modern browser capabilities to offer a seamless user experience. The cross-platform nature of PWAs enables the phishing campaign to effectively target both iOS and Android users, broadening its potential impact.

This novel phishing method was first disclosed by CSIRT KNF in Poland in July 2023. In November 2023, ESET analysts, through their Brand Intelligence service, [detected](https://www.welivesecurity.com/en/eset-research/be-careful-what-you-pwish-for-phishing-in-pwa-applications/) this technique in [Czechia](https://www.policie.cz/clanek/pozor-podvodnici-vymysleli-novy-system.aspx). 

Further investigations revealed that similar campaigns were targeting the Hungarian OTP Bank and the Georgian TBC Bank, indicating a broader geographical scope and a targeted attack strategy that leverages localized phishing techniques.

### **Key Insights from the Analysis**

- **Innovative Phishing Tactics**: The campaign cleverly blends traditional phishing delivery methods with advanced techniques, such as the deployment of PWAs and WebAPKs. These methods do not trigger alerts about installing third-party applications, effectively bypassing one of the primary defenses users rely on to avoid malicious apps.
- **Deceptive App Installation**: On Android devices, these malicious WebAPKs can appear to originate from the Google Play Store, thereby circumventing standard security warnings that would typically inform users about the risks associated with installing apps from unknown sources.
- **Targeted Regional Attacks**: While the campaign predominantly focused on Czech banks, evidence suggests that similar tactics were employed against financial institutions in Hungary and Georgia, showcasing the adaptability and geographical reach of the attackers.
- **Multiple Threat Actors**: The diversity in campaign infrastructure and the distinct nature of the Command & Control (C&C) servers suggest the involvement of at least two distinct threat actors, potentially collaborating or operating independently within a shared ecosystem of malicious tools and resources.
- **Proactive Defensive Measures**: The discovery of operational panels on various domains provided a rare opportunity for cybersecurity teams to notify the affected banks in a timely manner, mitigating the impact of the attacks and preventing further exploitation.

### **Campaign Delivery Mechanisms**

ESET researchers identified a sophisticated multi-pronged delivery strategy for these phishing campaigns, employing three distinct URL delivery mechanisms: automated voice calls, SMS messages, and social media malvertising.

1. **Automated Voice Calls**: Victims receive an automated call informing them that their banking app is outdated and needs immediate updating. The call prompts them to press a specific number on their keypad, after which a phishing URL is sent via SMS. This tactic exploits the urgency of the message and the authority of the automated voice to lower the victim's guard.
   
2. **SMS Phishing (Smishing)**: SMS messages containing phishing links were indiscriminately sent to a wide range of Czech phone numbers. These messages typically contained urgent language, warning users about unauthorized transactions or account suspensions to prompt quick action. This approach leverages the immediate nature of SMS communications to prompt quick user responses.
   
3. **Social Media Malvertising**: Ads were strategically placed on Meta platforms, such as Instagram and Facebook, featuring compelling calls to action (e.g., "download an update below"). These ads were tailored using user demographic data, such as age, location, and interests, increasing their effectiveness by making the ad appear relevant and urgent to the targeted user base.

Upon clicking the provided URLs, Android users were redirected to a high-quality phishing page meticulously crafted to mimic the official Google Play Store or a nearly identical clone of the targeted bank's website. This page dynamically adapts its appearance based on the user’s device, using responsive design principles to switch to an Apple Store-like interface if accessed from an iOS device, thus maintaining the illusion of legitimacy across platforms.

### **Phishing Workflow and Techniques**

Upon visiting the phishing website, victims are deceptively prompted to install a "new version" of their banking app. The specific approach varies depending on the platform:

- **For Android Users**: The phishing site initiates the download of a WebAPK. A WebAPK is a Web Application Package that functions similarly to a traditional APK but is generated by the Chrome browser from a PWA. This critical step bypasses the standard browser warnings about installing unknown apps due to Chrome’s WebAPK technology, which the attackers exploit by deploying it directly from a malicious server.

- **For iOS Users**: The phishing flow involves a convincingly animated pop-up that mimics native iOS prompts, instructing the user on how to add the malicious PWA to their home screen. This method effectively sidesteps the usual warnings about adding potentially harmful applications by using familiar-looking prompts and animations that exploit users' trust in their device’s native interfaces.

Once installed, these malicious apps prompt users to enter their banking credentials into a fake login screen that is visually identical to the legitimate app's interface. All entered data is immediately captured and transmitted to the attackers' C&C servers for exploitation.

### **Technical Analysis and Timeline of Observed Campaigns**

ESET’s timeline of the campaign provides a chronological insight into the attack's evolution:

- **Early November 2023**: Initial detection of phishing campaigns using PWAs, focusing on exploiting the inherent cross-platform nature of these web-based applications.
- **Mid-November 2023**: Shift towards WebAPK-based attacks on Android devices, exploiting Chrome’s native-like app behavior to bypass security warnings.
- **March 2024**: Discovery of Command & Control servers used to collect sensitive data from the phishing applications, indicating a coordinated and organized effort.
- **May 2024**: Detection of the cryptomaker[.]info server, which was involved in an attack against Georgian TBC Bank in February 2024, further highlighting the cross-border nature of these attacks and the attackers' adaptability.

### **Detailed Breakdown of PWA and WebAPK Phishing Methods**

#### **Progressive Web Applications (PWAs)**

The phishing strategy relies heavily on the use of PWAs, which are designed to operate like native applications across multiple platforms. PWAs are built using standard web technologies (HTML, CSS, JavaScript) but include advanced features like offline capabilities, push notifications, and the ability to be installed on a user's device directly from the browser. 
When a user is tricked into installing a PWA, a pop-up prompt appears, offering an installation option. Once installed, the PWA can operate like a native app, launching from the device’s home screen and running in a dedicated window without a visible browser frame, which enhances the illusion of legitimacy.

Key features of PWAs that make them attractive for phishing campaigns include:

- **Unified Codebase**: PWAs are platform-agnostic, meaning the same codebase can run on multiple operating systems, reducing the effort needed to target different devices.
- **Browser APIs and WebAssembly**: PWAs can leverage modern browser APIs, including WebAssembly, to execute near-native code within the browser environment, increasing their capability to perform sophisticated functions that go beyond traditional web apps.
- **Service Workers**: These background scripts enable PWAs to function offline by caching data and assets, making them operational even without an internet connection, thereby mimicking native app functionality more closely.

By carefully configuring the PWA’s manifest file, attackers can dictate how the app should appear and behave on the victim's device, including setting the app's name, icon, and startup URL. This level of control allows attackers to create a highly convincing imitation of legitimate banking apps.

#### **WebAPKs**

WebAPKs represent a more advanced version of the PWA concept specifically designed for Android devices. A WebAPK is a special type of Android application generated by the Chrome browser from a PWA. Unlike PWAs, WebAPKs are indistinguishable from native apps because they lack any browser-related UI elements, such as a browser logo overlay on the app icon. This makes them particularly effective for phishing, as they appear as legitimate apps in the user's app drawer.

Crucially, WebAPK installations do not trigger any security warnings about "installing from an untrusted source," even if the user has not enabled third-party installations. This behavior is a result of how Chrome handles PWA-to-WebAPK conversions, effectively exploiting a gap in Android’s security model that attackers have cleverly utilized to bypass user defenses and deploy malware surreptitiously.

### **Operational Insights and Infrastructure Analysis**

Our deep dive into the campaign infrastructure uncovered two distinct C&C infrastructures, suggesting collaboration or parallel operations by multiple threat groups:

1. **Primary Infrastructure**: Involved in the initial phishing domain setup and early-stage credential harvesting. This infrastructure was characterized by a series of rapidly changing IP addresses, dynamic DNS services, and robust domain-fronting techniques to obscure the true location of the servers.
   
2. **Secondary Infrastructure**: Identified through the analysis of network traffic and WHOIS data, this secondary infrastructure appears to serve as a backend for exfiltrating collected credentials and other sensitive data. It also employed multiple layers of obfuscation and encryption, including TLS certificate pinning and DNS-over-HTTPS (DoH), to avoid detection by traditional network security tools.


#### **Technical Mechanisms Behind Phishing Attacks**

Phishing campaigns utilizing PWAs and WebAPKs rely on several technical mechanisms to evade detection and enhance effectiveness:

- **Bypassing Security Warnings**: Unlike traditional mobile apps, PWAs do not require approval from app stores, allowing them to bypass many security checks. Attackers exploit this loophole to distribute malicious PWAs.
- **Exploiting C2 Infrastructure**: Command-and-control (C2) servers are used to manage phishing campaigns, distributing instructions to compromised devices and exfiltrating stolen data. WebAPKs can be updated remotely from a C2 server without user knowledge, increasing the persistence and adaptability of attacks.

### **3. Timeline and Campaign Analysis**

#### **Development of Phishing Campaigns Using PWAs and WebAPKs**

A detailed timeline of the evolution of these phishing campaigns highlights the adaptability of threat actors:

- **Phase 1**: Initial deployment of basic PWAs for data collection.
- **Phase 2**: Introduction of WebAPKs to increase attack surface and bypass more robust security measures.
- **Phase 3**: Incorporation of multi-factor authentication (MFA) interception techniques to gain access to more secure systems.

#### **Comparative Analysis of Threat Actor Groups**

Different threat actor groups utilize varying methods to deploy PWAs and WebAPKs:

- **Group A**: Focuses on using malvertising to distribute PWAs to a wide audience. Their campaigns are characterized by a high volume of fake ads and rapid deployment of new PWAs.
- **Group B**: Utilizes smishing and vishing to target specific individuals, often using spear-phishing techniques to customize attacks based on the victim's profile.
- **Group C**: Known for their sophisticated C2 infrastructure, which allows them to remotely manage and update WebAPKs on compromised devices without user intervention.

### **4. Impact and Broader Implications of These Phishing Techniques**

#### **Cross-Platform Nature and User Security Concerns**

The use of PWAs and WebAPKs in phishing attacks presents unique challenges:

- **Cross-Platform Impact**: Since PWAs are inherently cross-platform, they can target users on both desktop and mobile devices. This versatility increases the potential impact of phishing campaigns.
- **User Security and Privacy**: Attacks exploiting PWAs and WebAPKs compromise user privacy and security by installing malware, intercepting communications, and exfiltrating sensitive data.

#### **Potential Future Trends and Evolving Risks**

As technology evolves, so do the tactics used in phishing campaigns. Future trends may include:

- **Increased Sophistication of PWAs**: Attackers may develop more sophisticated PWAs that mimic legitimate apps more closely, making them harder to detect.
- **Expansion to Other Platforms**: With the growing popularity of non-Android operating systems, attackers may begin targeting iOS or desktop environments using similar techniques.


### **5. User Interaction, Awareness, and Mitigation Strategies**

#### **Exploiting User Behavior and Deceptive Interfaces**

Phishing campaigns heavily exploit user behavior and interface deception:

- **Deceptive User Interfaces**: Fake app installation prompts that mimic legitimate update notifications or system messages.
- **User Trust Exploitation**: Techniques that exploit user trust, such as mimicking government or financial institution websites.


### **Operational Insights and Infrastructure Analysis**

Our analysis of the campaigns revealed two distinct C&C infrastructures, indicating the involvement of two separate threat groups:

1. **Telegram Bot C&C**: This group employed a backend server to capture stolen login data, which was then forwarded to a private Telegram group via the official API. The presence of a stack trace on the phishing page inadvertently exposed the Telegram API and bot token used, providing crucial insights into their operational methods.

2. **Traditional C&C Server with Administrative Panel**: The second group managed a conventional C&C server equipped with an operator panel. This panel stored sensitive victim information, active phishing URLs, and a detailed history of interactions. When the initial domain (hide-me[.]online) was deactivated, the threat actors quickly established new domains to continue their operations. These activities also included a secondary campaign involving the NGate Android malware.

Thanks to the information retrieved from these panels, we were able to notify the affected banks and prevent further exploitation of their customers.

### **Emerging Threat: NGate Android Malware**

A newly identified threat, NGate, targets Android devices by intercepting data read by the near-field communication (NFC) chip, enabling attackers to emulate victims’ payment cards. This capability allows for unauthorized transactions and cash withdrawals from ATMs, further highlighting the evolving sophistication of mobile phishing tactics.

Miggo Research has identified a critical configuration-based vulnerability, dubbed **ALBeast**, which affects applications using AWS Application Load Balancer (ALB) for authentication. This vulnerability can facilitate an authentication and authorization bypass in applications exposed to the internet that rely on ALB’s authentication mechanisms. The resulting compromise threatens the confidentiality, integrity, and availability of affected applications, potentially leading to unauthorized access to business resources, data breaches, and data exfiltration.

**Key Highlights:**

- **Discovery Date:** April 6th, 2024
- **Reported To:** AWS Security Team
- **Mitigation:** AWS has updated documentation and added code validation requirements.
- **Impact:** Over 15,000 potentially vulnerable ALBs and applications identified.



### **ALBeast Vulnerability: A Deep Dive**

#### **What is ALBeast?**

ALBeast is a configuration-based vulnerability within the AWS ALB authentication [feature](https://www.miggo.io/resources/albeast-security-advisory-alb-vulnerability). It allows threat actors to bypass both authentication and authorization processes by exploiting improper configurations in applications using ALB for user authentication. The vulnerability stems from a flaw in the way AWS ALB handles token signing, leading to potential unauthorized access and severe security breaches.

#### **How Can Attackers Exploit ALBeast?**

An attacker exploiting ALBeast can achieve an authentication bypass with the highest level of permissions. 
The following steps outline how this exploitation occurs:

1. **Malicious ALB Creation:** The attacker sets up their own ALB instance with authentication configured in their account.
2. **Token Forging:** The attacker signs a token under their control, customizing the claims as needed.
3. **Configuration Manipulation:** The attacker alters the ALB configuration to match the victim's expected issuer in the token.
4. **Exploitation:** AWS signs the forged token with the victim's issuer, enabling the attacker to bypass both authentication and authorization defenses in the victim's application.

This process results in unauthorized access, potentially compromising critical business resources and data.



### **Impact and Response**

#### **AWS's Response to ALBeast**

Upon being informed of the vulnerability on April 6th, AWS swiftly updated the authentication feature documentation on May 1st, 2024.

- **Best Practices for Security Groups:** On July 19th, 2024, AWS further updated their documentation to recommend restricting targets to only receive traffic from the Application Load Balancer.

AWS’s official stance on this issue underlines the **shared responsibility model**. 

While AWS provides the infrastructure and basic security mechanisms, customers are responsible for ensuring their applications adhere to the updated documentation and configuration requirements.

#### **Impact Scope**

Since the discovery of ALBeast, Miggo Research has identified over **15,000 potentially vulnerable** ALBs and applications, out of 371,000 analyzed instances. Approximately 95% of implementations and open-source projects were found lacking signer validation, significantly increasing the risk of exploitation.

Miggo Research has taken proactive steps to contact each affected organization, providing support and guidance on necessary remediation actions.


### **Mitigation Strategies for ALBeast**

#### **Are You Vulnerable?**

AWS does not consider the issuer forging an inherent ALB vulnerability but rather an exploitation of a configuration oversight. This distinction places the responsibility on customers to secure their applications by following AWS’s updated guidance.

To determine if your application is vulnerable, check whether it uses ALB user authentication and if it adheres to the updated [AWS documentation](https://docs.aws.amazon.com/elasticloadbalancing/latest/application/listener-authenticate-users.html). Failure to implement these updates may leave your application exposed to potential attacks.

#### **Mitigation Steps:**

1. **Token Signer Validation:** Ensure every application using the ALB authentication feature rigorously checks the token signer.
2. **Restrict Traffic Sources:** Configure your application’s security groups to only accept traffic from trusted ALB instances.

These steps are crucial in mitigating the risk posed by ALBeast. AWS has reflected these requirements in its latest [ALB authentication documentation](https://www.miggo.io/resources/uncovering-auth-vulnerability-in-aws-alb-albeast).

A previously unseen backdoor, dubbed *Msupedge*, has been identified targeting a university in Taiwan. This malicious tool leverages a sophisticated and infrequently used method of communication, utilizing DNS traffic to establish a covert channel with its Command-and-Control (C&C) server. The emergence of this backdoor is particularly concerning, as it underscores the persistent evolution of cyber threats exploiting newly discovered vulnerabilities to infiltrate systems.

This Threatfeed aims to provide an in-depth analysis of the Msupedge backdoor, its infection vector, methods of communication, operational commands, and potential mitigation strategies. We will also delve into the specific vulnerabilities exploited by threat actors, with a focus on the recently patched PHP remote code execution flaw (CVE-2024-4577). 

###  Emergence of Msupedge

#### Msupedge Overview

*Msupedge* is a sophisticated backdoor implemented as a dynamic link library (DLL). It was discovered during an investigation into a cyberattack against a Taiwanese university. The backdoor's distinguishing characteristic is its use of DNS tunneling for C&C communication—a method not frequently observed in the wild, despite being known in cybersecurity circles.

The backdoor has been installed in the following file paths on the compromised systems:

- **csidl_drive_fixed\xampp\wuplog.dll**
- **csidl_system\wbem\wmiclnt.dll**

The *wuplog.dll* is loaded by the Apache HTTP server process (httpd.exe), while the parent process for *wmiclnt.dll* remains unidentified.

### DNS Tunneling: Msupedge’s Stealthy Communication Mechanism

The most notable feature of *Msupedge* is its use of DNS tunneling to communicate with its C&C server. DNS tunneling allows data to be encapsulated within DNS queries and responses, enabling covert communication channels that are difficult to detect. The backdoor's DNS tunneling capability is based on the open-source dnscat2 tool, which is publicly available and has been utilized by various threat actors in the past.

#### Command Execution via DNS Traffic

*Msupedge* receives commands from its C&C server by performing DNS name resolution. The hostnames that are resolved are structured to convey specific instructions, and the results of command executions are encoded into the DNS responses. This method allows the backdoor to perform various malicious actions while remaining under the radar.

The backdoor also uses the resolved IP address of the C&C server (*ctl.msedeapi[.]net*) as a command input. Specifically, the third octet of the resolved IP address plays a critical role in determining the behavior of the backdoor. The value of this octet, minus seven, dictates the specific action the backdoor will take. For example, if the third octet is 145, it translates to 138 (0x8a in hexadecimal), triggering a particular command.

### Detailed Analysis of Msupedge Commands

*Msupedge* supports multiple commands, which are executed based on the DNS responses received from the C&C server. The following is a breakdown of the commands supported by the backdoor:

- **Case 0x8a**: Create a new process. The command is received via a DNS TXT record.
- **Case 0x75**: Download a file. The download URL is provided through a DNS TXT record.
- **Case 0x24**: Induce the system to sleep for a specified duration, calculated as `ip_4 * 86400 * 1000 ms`.
- **Case 0x66**: Another sleep command, with the duration set to `ip_4 * 3600 * 1000 ms`.
- **Case 0x38**: Create a temporary file at `%temp%\1e5bf625-1678-zzcv-90b1-199aa47c345.tmp`. The purpose of this file remains unclear.
- **Case 0x3c**: Remove the previously created temporary file.

These commands demonstrate the flexibility and control *Msupedge* grants its operators, enabling them to execute a range of malicious activities on compromised systems.

### Infection Vector: The Exploitation of PHP RCE Flaw (CVE-2024-4577)

The initial intrusion leading to the deployment of *Msupedge* is believed to have been facilitated through the exploitation of a recently patched PHP vulnerability—CVE-2024-4577. This critical flaw is a CGI argument injection vulnerability affecting all versions of PHP installed on Windows systems running in CGI mode.

CVE-2024-4577 bypasses protections previously implemented by the PHP team for CVE-2012-1823, which was exploited in historical malware attacks targeting Linux and Windows servers. Successful exploitation of this flaw allows unauthenticated attackers to execute arbitrary code on the affected systems, leading to full system compromise.

#### Timeline of Exploitation

Symantec’s Threat Hunter Team, who discovered the *Msupedge* backdoor, observed that the initial compromise likely occurred shortly after the release of patches for CVE-2024-4577. The vulnerability quickly garnered attention from multiple threat actors, who began scanning for vulnerable systems. Notably, the TellYouThePass ransomware gang started exploiting this flaw less than 48 hours after patches were released, highlighting the speed at which attackers can capitalize on newly disclosed vulnerabilities.

### Indicators of Compromise (IOCs) and Mitigation Strategies

To protect against *Msupedge* and similar threats, it is crucial to monitor for specific Indicators of Compromise (IOCs). Symantec Endpoint products are equipped to detect and block malicious files associated with this backdoor. Some of the key IOCs include:

- **e08dc1c3987d17451a3e86c04ed322a9424582e2f2cb6352c892b7e0645eda43** – *Msupedge* backdoor
- **f5937d38353ed431dc8a5eb32c119ab575114a10c24567f0c864cb2ef47f9f36** – *Msupedge* backdoor
- **a89ebe7d1af3513d146a831b6fa4a465c8edeafea5d7980eb5448a94a4e34480** – Web shell

### Protection and Mitigation

Given the sophisticated nature of *Msupedge* and its stealthy communication techniques, it is essential to implement robust security measures. Organizations should ensure that all systems are patched promptly, particularly those running PHP in CGI mode. Regularly updating antivirus and endpoint protection software is also critical to detecting and mitigating such threats.

Furthermore, network traffic should be closely monitored for unusual DNS queries, which may indicate the presence of DNS tunneling activities. Implementing DNS filtering and blocking known malicious domains can also help prevent communication with C&C servers.



The discovery of the *Msupedge* backdoor highlights the ever-evolving tactics employed by cybercriminals to infiltrate systems and maintain persistence. By exploiting the CVE-2024-4577 vulnerability, attackers were able to deploy a highly sophisticated backdoor capable of executing a wide range of commands via DNS traffic.

To defend against such threats, it is imperative for organizations to stay vigilant, promptly apply security patches, and employ comprehensive monitoring solutions. As cyber threats continue to evolve, so too must the strategies and technologies we use to combat them.

Here’s a step-by-step breakdown of its execution process:

1. **Command Line Execution**: The attacker initiates EDRKillShifter with a password-protected command line. The correct password decrypts an embedded resource named BIN in memory.

2. **Payload Execution**: The BIN code then unpacks and executes the final payload, which is a Go-language binary designed to exploit vulnerable drivers.

3. **Driver Exploitation**: The final payload drops and exploits a legitimate driver to bypass EDR protections.

**2. Self-Modifying Code**

The EDRKillShifter employs self-modifying code techniques, altering instructions during runtime to evade detection. This obfuscation makes analysis challenging, requiring specialized tools for effective reverse engineering.

**3. Payload Analysis**

The final payloads are written in Go and are often obfuscated. This approach complicates reverse engineering efforts by encrypting strings, removing version information, and hiding package paths.

### **Mitigation Strategies**

To counter the threat posed by EDRKillShifter, consider the following mitigation strategies:

**1. Enable Tamper Protection**

Ensure that tamper protection is enabled in endpoint security products. This feature helps safeguard against unauthorized modifications and attacks designed to disable security measures.

**2. Practice Strong Role Separation**

Maintain clear separation between user and admin privileges. This practice limits the potential for attackers to escalate privileges and load vulnerable drivers.

**3. Keep Systems Updated**

Regularly update systems and software. Microsoft’s efforts to de-certify misused signed drivers underscore the importance of keeping systems current to avoid exploitation.

### **Comparison with Previous EDR-Killers**

**EDRKillShifter** shares similarities with previous EDR-killing malware like **AuKill**, discovered last year. Both tools exploit legitimate drivers but differ in their specific techniques and the types of drivers they target. The evolution of these tools reflects the increasing sophistication of cyber threats.

### **Current Threat Landscape**

The broader threat landscape shows a growing trend of EDR-killing tools, highlighting the need for continuous vigilance and adaptive security measures. EDRKillShifter’s design and execution illustrate the persistent challenge of defending against advanced persistent threats (APTs) and sophisticated cyber attacks.

### **Additional Insights**

**1. Loader and Payload Variability**

EDRKillShifter variants demonstrate significant variability in the drivers and payloads used. This adaptability allows threat actors to customize their attacks based on the target environment and available vulnerabilities.

**2. Dark Net and Obfuscation Tools**

The sale of obfuscators and loaders on the dark net underscores the commercial aspect of cyber threats. Sophos X-Ops suggests that these tools might be obtained from illicit sources and used to deploy various malicious payloads.




**EDRKillShifter** represents a notable advancement in EDR-killing malware, utilizing sophisticated techniques to disable endpoint protections.

6. CVE-2024-38213 (CVSS score: 6.5) - Windows Mark of the Web Security Feature Bypass Vulnerability

CVE-2024-38213, which enables attackers to circumvent SmartScreen protections, necessitates an attacker sending a malicious file to a user and persuading them to open it. 

Peter Girnus of Trend Micro, who discovered and reported the flaw, suggests that it could serve as a bypass for CVE-2024-21412 or CVE-2023-36025, both of which were previously exploited by DarkGate malware operators.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has incorporated these flaws into its Known Exploited Vulnerabilities (KEV) catalog. Consequently, federal agencies are mandated to apply the fixes by September 3, 2024.

Four of the following CVEs are recognized as publicly known:

1. CVE-2024-38200 (CVSS score: 7.5) - Microsoft Office Spoofing Vulnerability
2. CVE-2024-38199 (CVSS score: 9.8) - Windows Line Printer Daemon (LPD) Service Remote Code Execution Vulnerability
3. CVE-2024-21302 (CVSS score: 6.7) - Windows Secure Kernel Mode Elevation of Privilege Vulnerability
4. CVE-2024-38202 (CVSS score: 7.3) - Windows Update Stack Elevation of Privilege Vulnerability

Scott Caveza, a research engineer at Tenable, provided insight on CVE-2024-38200, stating that an attacker could exploit this vulnerability by enticing a victim to access a specially crafted file, likely via a phishing email. Successful exploitation could lead to the victim exposing New Technology Lan Manager (NTLM) hashes to a remote attacker. These NTLM hashes could be leveraged in NTLM relay or pass-the-hash attacks to deepen an attacker's foothold within an organization.

The update also addresses a privilege escalation flaw in the Print Spooler component (CVE-2024-38198, CVSS score: 7.8), which enables an attacker to acquire SYSTEM privileges. Microsoft noted that successful exploitation of this vulnerability necessitates an attacker winning a race condition.

However, Microsoft has yet to roll out updates for CVE-2024-38202 and CVE-2024-21302, which could potentially be exploited to stage downgrade attacks against the Windows update architecture and replace current versions of the operating system files with older versions.

Fortra recently reported a denial-of-service (DoS) flaw in the Common Log File System (CLFS) driver (CVE-2024-6768, CVSS score: 6.8) that could trigger a system crash, resulting in a Blue Screen of Death (BSoD). When asked for comment, a Microsoft spokesperson informed that the issue _"does not meet the bar for immediate servicing under our severity classification guidelines and we will consider it for a future product update."_

The spokesperson added, _"The technique described requires an attacker to have already gained code execution capabilities on the target machine and it does not grant elevated permissions. We encourage customers to practice good computing habits online, including exercising caution when running programs that are not recognized by the user."_

SinkClose: A High-Severity AMD CPU Vulnerability Enables Undetectable Malware

Browsers are integral to our daily online activities, and non-browser applications often rely on external domains for resources. Recent research has unveiled a critical security flaw known as the 0.0.0.0 Day vulnerability exploits a significant flaw in how browsers handle requests to specific IP addresses, such as 0.0.0.0, potentially allowing malicious sites to interact with local services.

Browsers, by design, can send requests to almost any HTTP server using JavaScript. Despite advanced security measures like sandboxing and CORS, vulnerabilities persist, such as the 0.0.0.0 Day flaw. This vulnerability allows malicious websites to circumvent browser security mechanisms and interact with local services, eventually exploiting them through seemingly benign requests, potentially leading to unauthorized access and remote code execution.

This [Threatfeed](https://www.secureblink.com/cyber-security-news) provides an in-depth analysis of the vulnerability, its implications, and current remediation efforts.



### **What is the 0.0.0.0 Day Vulnerability?**

The IP address 0.0.0.0 serves various functions, such as indicating "all IPs on this host" or "all network interfaces on this host," and is used in contexts like DHCP configurations or ad-blocking. However, its role as a target IP address in HTTP requests poses a significant security risk. The "0.0.0.0 Day" vulnerability exploits inconsistencies in how major web browsers handle network requests involving this IP address. Unlike `127.0.0.1` or `localhost`, which refer specifically to the local machine, `0.0.0.0` can be misinterpreted by browsers in ways that enable external websites to interact with local services, bypassing traditional security checks.


**In early April 2024, [Oligo disclosed](https://www.oligo.security/blog/0-0-0-0-day-exploiting-localhost-apis-from-the-browser) the "0.0.0.0 Day" vulnerability to major browser security teams.

### **Why is this website port scanning me?**

The 0.0.0.0 Day vulnerability exacerbates port scanning issues. Attackers can use this technique to gather sensitive information from local services, which may then be exploited for further attacks. This also facilitates digital fingerprinting and intelligence gathering for phishing and other malicious purposes.

### **An 18-year-old bug?**

This vulnerability highlights long-standing issues with internal network security. A 2006 Mozilla report illustrates how browsers have struggled with similar flaws, showing that vulnerabilities like the [0.0.0.0 Day](https://github.com/whatwg/fetch/pull/1763) have evolved and persisted over time.

### **What is PNA (Private Network Access)?**

Private Network Access (PNA) was introduced to address how browsers handle requests to local or internal networks, aiming to prevent domains from contacting sensitive local addresses like `localhost`. 

However, our analysis revealed that despite PNA's intent to restrict access to private IP addresses, `0.0.0.0` was not included in the restricted list. This oversight allowed us to successfully send requests to `0.0.0.0`, bypassing PNA protections and exposing local services to potential exploitation.




### **Technical Details**

1. **Vulnerability Mechanism**: Browsers handle HTTP requests to `0.0.0.0` inconsistently, often due to varying implementations of security standards. This inconsistency can allow a malicious website to send requests to `0.0.0.0`, which are then routed to local services running on a user's machine. This can include development environments, operating systems, or internal network services.

2. **Impacted Services**: Services running on local networks, particularly those designed to be accessed only from within a trusted environment, are at risk. This includes development tools, internal databases, and local web servers. Attackers can exploit these services to execute arbitrary code or access sensitive information.

### **Finding Vulnerable Local Applications**

Identifying vulnerable local applications is crucial, as many applications are susceptible to the 0.0.0.0 Day vulnerability. Applications often assume a secure environment on `localhost`, but this assumption can lead to severe security issues when external sites exploit these services.

### **Real-World Exploits**


Recent discoveries have revealed active exploitation campaigns utilizing this vulnerability. The researchers proved the concept within Chromium, Safari, and Firefox to execute ShadowRay from the browser, highlighting one of the numerous remote code execution attacks enabled by this approach. 

Additionally, they demonstrated the attack via Selenium Grid public servers and PyTorch TorchServe through previously identified campaigns, [SeleniumGreed](https://www.secureblink.com/cyber-security-news/new-cyberattack-targets-docker-ap-is-with-advanced-cryptojacking-tactics-1) and ShellTorch.

One notable instance, dubbed ShadowRay, demonstrated the potential for remote code execution via 0.0.0.0, allowing attackers to gain unauthorized access to AI workloads on local systems. Another instance involves Selenium Grid, where attackers exploited the vulnerability to access internal systems by sending crafted requests to 0.0.0.0.

- **ShadowRay**: [Demonstrated](https://www.oligo.security/blog/shadowray-attack-ai-workloads-actively-exploited-in-the-wild) remote code execution via `0.0.0.0`, allowing attackers to gain unauthorized access to AI workloads running on local systems.
   - **Selenium Grid**: Attackers used the vulnerability to access internal systems by sending crafted requests to `0.0.0.0`.



### **Current Remedial Actions**

1. **Browser Responses**:
   - **Google Chrome**: Acknowledges the issue and is implementing changes to block `0.0.0.0` in version 133.
   - **Apple Safari**: Modified WebKit to block requests to `0.0.0.0`.
   - **Mozilla Firefox**: Committed to updating its Fetch specification to address the vulnerability in future releases.

2. **Standards and Specifications**: The Request for Comment (RFC) process is being used to formalize a standard to prevent the use of `0.0.0.0` as a target IP address. This initiative aims to unify browser behavior and close the security gap exploited by this vulnerability.

### **Mitigation Strategies**

Developers should:
   - **Restrict Access**: Implement robust authentication and authorization for local services.
   - **Monitor Network Traffic**: Regularly audit network traffic for unauthorized access.
   - **Update Software**: Keep all software and services updated with the latest security patches.

#### Conclusion: How Local Is Your Localhost?


The 0.0.0.0 Day vulnerability highlights critical security challenges related to browser network request handling. While browser-level fixes are underway, developers and organizations must adopt complementary security practices. Until PNA is fully implemented across all browsers, public websites can still exploit local services, underscoring the need for immediate protective measures. The persistence of this issue underscores the need for ongoing collaboration among browser vendors and adherence to emerging standards.

For further details, monitor browser update logs and RFC publications to stay informed about the latest security measures and best practices.

Business Email Compromise (BEC) scams are a type of cybercrime where a malicious actor poses as a trusted figure and uses legitimate email tricking targets into sending money or divulging confidential company information. These attacks can occur in various ways, including gaining unauthorized access to a finance employee or a law firm's email account to send fake invoices or impersonating a third-party vendor to email a phony bill.

In mid-July 2024, an unnamed commodity firm based in Singapore fell victim to a [BEC scam](https://www.microsoft.com/en-us/security/business/security-101/what-is-business-email-compromise-bec). The firm received an email from a supplier requesting that a pending payment be sent to a new bank account based in [Timor-Leste](https://www.interpol.int/News-and-Events/News/2024/Police-recover-over-USD-40-million-from-international-email-scam). 

However, the email came from a fraudulent account spelled slightly different from the supplier's official email address. The Singaporean company transferred $42.3 million to the non-existent supplier on July 19, only to realize the blunder on July 23 after the actual supplier said it had not been compensated.

## INTERPOL's I-GRIP Mechanism

[INTERPOL](https://www.secureblink.com/cyber-security-news/operation-pangea-xiv-was-seized-busting-thousands-of-fake-online-pharmacies-by-interpol)'s Global Rapid Intervention of Payments (I-GRIP) mechanism is a stop-payment mechanism that helps authorities trace, intercept, and freeze proceeds of crimes across borders. 

By taking advantage of I-GRIP, authorities in Singapore managed to detect $39 million and froze the counterfeit bank account a day later. 

Since its launch in 2022, I-GRIP has helped law enforcement intercept hundreds of millions of dollars in illicit funds.

## Cryptonator: A Case Study

Cryptonator, an online digital wallet and cryptocurrency exchange, was seized by law enforcement for allegedly receiving criminal proceeds of computer intrusions and hacking incidents, ransomware scams, various fraud markets, and identity theft schemes. Launched in December 2013 by Roman Boss, Cryptonator facilitated more than 4 million transactions worth a total of $1.4 billion. 

![crypto.webp](https://sb-cms.s3.ap-south-1.amazonaws.com/crypto_0ec5f481fb.webp)
***Seized Site***

This comprised money exchanged with darknet markets, scam wallet addresses, high-risk exchanges, ransomware groups, crypto theft operations, mixers, and sanctioned addresses.

## Role of Blockchain Protocols

The popularity of cryptocurrency has created plenty of opportunities for fraud, with threat actors constantly devising new ways to drain victims' wallets. Fraudsters are abusing legitimate blockchain protocols like Uniswap and Safe.global to conceal their malicious activities and siphon funds from cryptocurrency wallets.

Attackers leverage the Uniswap Multicall [contract](https://research.checkpoint.com/2024/unveiling-the-scam-how-fraudsters-abuse-legitimate-blockchain-protocols-to-steal-your-cryptocurrency-wallet/) to orchestrate fund transfers from victims' wallets to their own. The Uniswap Multicall contract enables calling multiple methods in a single call to the contract.

Attackers have also been known to use the Gnosis Safe contracts and framework, coaxing unsuspecting victims into signing off on fraudulent transactions. The Gnosis Safe is a smart contract that uses multi-sig. It functions as a deployed smart contract with a public address. Transaction signing is done via a customized logic tailored for specific use.



[INTERPOL](https://www.secureblink.com/cyber-security-news/operation-lyrebird-led-by-interpol-joined-by-group-ib-to-nab-the-attackers-active-globally) is encouraging businesses and individuals to take preventative steps to avoid falling victim to BEC and other social engineering scams¹.

Web browser extensions have evolved from niche software into a thriving sub-economy within the internet industry. Most browsers, including Microsoft Edge and Google Chrome, support extensions, offering hundreds of thousands of options in their respective stores. However, the rising popularity of extensions has also attracted bad actors, leading to a surge in malicious extensions that exploit this relatively new malware attack vector. 

This [Threatfeed](https://www.secureblink.com/cyber-security-news) aims to shed light on the broader issue of malicious web extensions, focusing on a specific ongoing threat.

### **Forcefully Installed Malicious Extensions**

The ReasonLabs Research Team has uncovered a new and widespread polymorphic malware campaign that forcibly installs extensions on user devices. 

This Trojan malware, which has been active since 2021, employs various tactics, ranging from simple adware extensions that hijack searches to more sophisticated malicious scripts that deliver local extensions designed to steal private data and execute arbitrary commands. The malware originates from deceptive download websites that mimic legitimate sources, offering add-ons for popular online games and videos. 

The reach of this malware is extensive, with at least 300,000 users across Google Chrome and Microsoft Edge impacted.

### **Attack Flow: From Fake Downloads to Browser Compromise**

The malware campaign begins with seemingly innocuous downloads from fake websites that impersonate legitimate platforms like Roblox FPS Unlocker, YouTube, VLC, or KeePass. 

These websites distribute Trojan installers that, instead of installing the desired software, register scheduled tasks with misleading names (e.g., Updater_PrivacyBlocker_PR1, MicrosoftWindowsOptimizerUpdateTask_PR1, NvOptimizerTaskUpdater_V2). 

These tasks execute PowerShell scripts that download and run malicious payloads directly into memory, often bypassing detection by antivirus software.

***PowerShell scripts serve several key functions:***

- **Force Installation of Extensions:** They modify registry values to forcefully install malicious extensions from the browser's official store. These extensions frequently hijack search queries and are designed to be difficult or impossible for users to disable.

- **Disable Browser Updates:** Newer versions of the script also disable browser updates, preventing users from receiving crucial security patches that could mitigate the threat.

- **Load Local Extensions:** They tamper with browser shortcut files (`.lnk`) to load local extensions that further compromise the user's system. These local extensions focus on stealing search queries and can also communicate with the attacker's command-and-control (C&C) server, employing obfuscation techniques to evade detection.

- **Communicate with C&C:** The script maintains persistent communication with the C&C server to report its status and receive further instructions, downloading and executing additional scripts as needed.

### **PowerShell Script Analysis**

The PowerShell scripts are central to the attack, facilitating the download of malicious extensions and the manipulation of browser settings. 

They communicate with the C&C server, receiving instructions on which extensions to install, where to store downloaded files, and how to modify browser shortcuts. They also disable browser updates to maintain their persistence.

### **Third-Stage Script: Hijacking the Search Engine**

The attack culminates with a third-stage script that modifies browser DLLs (Dynamic Link Libraries) to hijack the default search engine. 

This script identifies the browser's DLL files, changes specific bytes within them, and redirects search queries to the attacker's search portal, allowing them to control and monetize the user's search activity.

### **User Impact and Frustration**

The forceful installation of these malicious extensions has caused significant frustration among users who find themselves unable to remove them. Many users mistakenly believe the issue lies within their browser and attempt to reinstall it, only to find the malicious extensions reappear.

### **Call to Action: Prevention and Protection**

The rise of malicious web extensions underscores the importance of user vigilance and proactive security measures. Users should be wary of downloading extensions from unknown sources and exercise caution when granting permissions.  

Employing next-generation antivirus software and advanced endpoint security tools can provide robust defense against malware and other threats.  However, the responsibility also lies with antivirus providers and endpoint security vendors to prioritize and address these emerging threats to protect their users effectively.


The malicious web extension campaign described in this article highlights the growing threat landscape surrounding browser extensions.  Both users and security professionals must remain vigilant and take proactive steps to defend against these evolving threats. By staying informed and adopting robust security practices, we can mitigate the risks associated with malicious web browser extensions and safeguard our digital experiences.

Guardio Labs identified "EchoSpoofing," a critical in-the-wild exploit that compromised Proofpoint's email protection service, a cornerstone for 87 of the Fortune 100 companies. 

This vulnerability allowed threat actors to launch a massive phishing campaign, dispatching millions of convincingly spoofed emails that leveraged the trusted reputations of Proofpoint's high-profile clients, including major brands like Disney, IBM, and Coca-Cola. 

These emails, seemingly originating from official Proofpoint email relays and bearing authenticated SPF and DKIM signatures, bypassed major security protections, deceiving recipients and potentially compromising sensitive financial data.

### **Discovering the Mechanics of EchoSpoofing: A Technical Analysis**

EchoSpoofing exploited a combination of vulnerabilities in core email authentication protocols – Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and crucially, Domain-based Message Authentication, Reporting, and Conformance (DMARC). 

By manipulating Proofpoint's email relay servers and leveraging compromised Microsoft Office365 accounts, attackers could inject spoofed "FROM" headers into emails, making them appear to originate from legitimate domains. These emails, convincingly signed with authentic DKIM keys and passing DMARC checks, bypassed conventional spam filters and reached millions of unsuspecting inboxes.

### **Art of Deception: Dissecting a Spoofed Email**

EchoSpoofing emails were meticulously crafted to mimic legitimate notifications or promotional offers from trusted brands. These emails often included fake Disney+ offers or account notifications, luring victims to phishing pages designed to harvest sensitive financial data or credentials.

The emails' effectiveness lies in their technical authenticity. The "FROM" header accurately displayed the targeted domain, the content was signed with the domain's genuine DKIM key, and they even passed DMARC authentication checks. This trifecta of forged legitimacy fooled both email providers and recipients into believing the emails were genuine.

### **Attack Infrastructure: PowerMTA and a Vast Network**

Behind [EchoSpoofing](https://labs.guard.io/echospoofing-a-massive-phishing-campaign-exploiting-proofpoints-email-protection-to-dispatch-3dd6b5417db6) was a extensive and sophisticated infrastructure. Attackers leveraged PowerMTA, a high-performance email delivery software often abused in spam and phishing campaigns. Operating from a network of virtual private servers (VPSs) hosted on providers like OVH, they were able to send a daily average of 3 million emails, with peaks reaching up to 14 million.

The attackers' tactics were cunning and evasive. They rotated domains and Office365 accounts, sent emails in bursts to avoid detection, and even monitored the success of their campaign by tracking the opening of malicious links. Evidence from their PowerMTA logs suggests they operated across a cluster of 11 servers, using cracked license keys obtained from illicit sources.

### **Proofpoint's Rapid Response and Mitigation Challenges**

Upon notification by Guardio Labs in May 2024, Proofpoint swiftly mobilized to address the exploit. However, they faced significant challenges due to the complexity of the issue and the need to avoid disrupting customers' email operations. The exploit had been active since January, giving attackers a considerable head start.

Proofpoint initiated a multi-pronged response, including direct customer outreach, configuration updates, and collaboration with security researchers. A key mitigation strategy was introducing a new feature leveraging the `X-OriginatorOrg` header, a unique identifier added by Microsoft Exchange to outgoing emails. This allowed customers to filter emails based on their legitimate Office365 tenants, effectively blocking spoofed messages.

### **Guardio Labs: Validating the Defense and Exposing the Exploit**

[Guardio Labs](http://www.guard.io/) has been instrumental in discovering the exploit and validating the effectiveness of [Proofpoint](https://www.proofpoint.com/us/blog/threat-insight/scammer-abuses-microsoft-365-tenants-relaying-through-proofpoint-servers-deliver)'s mitigation strategies. They rigorously tested the proposed solutions, including the use of the `X-OriginatorOrg` header, to ensure their robustness against potential bypass techniques. Their thorough analysis and collaboration with Proofpoint were instrumental in neutralizing the threat.

### **Impact and Fallout**

While Proofpoint's swift action helped mitigate the immediate threat, the EchoSpoofing incident had a significant impact. Major brands faced potential reputational damage and financial losses due to the phishing emails sent in their name. The exploit also raised broader concerns about the security of email infrastructure and the need for continuous vigilance.
