A developer documented their real-time response to discovering a malware-infected version of the LiteLLM package (v1.82.8) on PyPI. The malicious code was hidden in a .pth file within the package and executed base64-encoded payloads upon installation. The incident highlights supply chain security risks in the AI/LLM ecosystem and the use of AI assistants like Claude to analyze and report such threats.
Background
Software supply chain attacks, where malicious code is injected into open-source packages, are a growing threat to developers and organizations. PyPI (Python Package Index) is a common target due to its widespread use in the AI/ML community.
