Anthropic recently reported "Hackers Exploit Claude Code Leak to Spread Vidar Infostealer and GhostSocks Malware", a noteworthy cybersecurity incident.

Cybercriminals leveraged the accidental leak of Anthropic’s Claude Code source code to distribute malware via fake GitHub repositories.

The disruption is felt across the environment, affecting Infected machines repurposed as residential proxies, and exposing Browser data, passwords, cryptocurrency wallets.

In response, moved swiftly to contain the threat with measures like GitHub removed the offending account (dbzoomh).

The case underscores how Ongoing (malicious repos removed, but payloads may evolve), teams are taking away lessons such as Need for stricter source code access controls, rapid response to leaks, and enhanced monitoring of third-party repositories, and recommending next steps like Implement stricter access controls for sensitive code, monitor for unauthorized forks/repositories, educate employees on secure handling of proprietary code, and enhance threat detection for malware distribution via code leaks, with advisories going out to stakeholders covering Users warned against downloading unofficial Claude-related executables or repositories.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
