Weekly Cybersecurity Digest: Top 5 News Stories in the Digital Sphere

1. Massive Git Config Breach Exposes 15,000 Credentials

A significant cybersecurity breach, known as EMERALDWHALE, has exposed over 15,000 credentials and cloned 10,000 private repositories by targeting vulnerable Git configurations. This operation leveraged tools like MZR V2 and Seyzo-v2 to siphon sensitive information from Git config files and Laravel .env files, primarily affecting cloud service and email providers. The stolen credentials have been stored in an Amazon S3 bucket, which has since been taken down. Additionally, a list of 67,000 exposed Git URLs is reportedly being sold on Telegram, highlighting the growing underground market for stolen data. This incident emphasizes the urgent need for robust credential management and security practices to protect sensitive information.

Key Points:

• Incident Name: EMERALDWHALE
• Credentials Exposed: Over 15,000
• Private Repositories Cloned: 10,000
• Targeted Files: Git config files and Laravel .env files
• Main Tools Used: MZR V2 and Seyzo-v2
• Underground Market: 67,000 exposed Git URLs available for sale on Telegram
• Call to Action: Urgent need for enhanced credential management and security measures

3. Critical Flaws in Ollama AI Framework Could Enable DoS, Model Theft, and Poisoning

Researchers have identified six security vulnerabilities in the Ollama AI framework , which could be exploited by malicious actors for denial-of-service (DoS) attacks, model poisoning, and model theft. Ollama, an open-source application for deploying large language models (LLMs) locally, has been forked over 7,600 times on GitHub.

The vulnerabilities include:

• CVE-2024-39719: File existence detection via the /api/create endpoint (CVSS score: 7.5, fixed).
• CVE-2024-39720: Out-of-bounds read causing crashes (CVSS score: 8.2, fixed).
• CVE-2024-39721: Resource exhaustion leading to DoS (CVSS score: 7.5, fixed).
• CVE-2024-39722: Path traversal vulnerability exposing server files (CVSS score: 7.5, fixed).
• Two unpatched vulnerabilities that could lead to model poisoning and theft via the /api/pull and /api/push endpoints.

Users are advised to limit the exposure of these endpoints using a proxy or web application firewall, as many instances of Ollama remain vulnerable.

Key Points:

• Framework: Ollama AI
• Exploitable Vulnerabilities: 6 identified, including DoS, model poisoning, and theft
• CVE Identifiers: 4 fixed, 2 unpatched
• Open-Source Deployment: Used for large language models on multiple OS
• Internet-Facing Instances: 9,831 identified, primarily in the U.S., China, and Europe
• Recommendation: Use proxies/firewalls to restrict endpoint access

5. Malware Campaign Uses Ethereum Smart Contracts to Control npm Typosquat Packages

A recent malware campaign is targeting npm developers by releasing numerous typosquatted packages designed to install cross-platform malware. This campaign uses Ethereum smart contracts for distributing command-and-control server addresses, making it harder to block. As of October 31, 2024, at least 287 typosquat packages have been detected, containing obfuscated JavaScript that retrieves binaries from remote servers to exfiltrate sensitive data. The decentralized nature of blockchain enhances the resilience of the attack infrastructure, complicating detection and mitigation efforts.

Key Points:

• Ongoing npm malware campaign utilizes typosquatting.
• 287 malicious packages identified.
• Ethereum smart contracts used for C2 address distribution.
• Obfuscated JavaScript retrieves binaries to exfiltrate data.
• Decentralized architecture complicates blocking efforts.
