Threat Risk: High
Victim: Users of LiteLLM version 1.107.0
Incident: Supply chain compromise of the LiteLLM Python package delivering a stealer and backdoor.
Impact: Theft of sensitive cloud, AI, and browser credentials and potential remote code execution on developer systems.
Attacker: Unidentified threat actors
Analysis: Threat actors utilized stolen GitHub CLI OAuth tokens to hijack the release process for LiteLLM version 1.107.0. The malicious update deployed a credential stealer and a backdoor via a .pth file, ensuring automatic execution upon interpreter startup. This attack specifically targeted high-value assets including cloud tokens, private keys, and AI development credentials.
Recommendations: Immediately downgrade to LiteLLM version 1.106.2 and pin the version by digest.; Revoke and rotate all cloud credentials, private keys, and API tokens potentially exposed.; Audit GitHub OAuth tokens and implement stricter access controls for CI/CD release pipelines.
