Textbook PyPI supply chain attack, now targeting AI infrastructure. Treat your LLM stack like any other production dependency.

What is this and why should I care? LiteLLM is a popular open-source proxy that translates between OpenAI-compatible APIs and other LLM backends, widely used to route apps through self-hosted or private cloud models.

Impact: Version 1.82.8 on PyPI contains a malicious .pth file that executes a credential stealer automatically every time Python starts. No import required.

What it grabs: environment variables, SSH keys, AWS/GCP/Azure credentials, Kubernetes configs, shell history, Docker configs, git credentials, and crypto wallets. Everything is encrypted and exfiltrated to an attacker-controlled server.

If you installed litellm==1.82.8, assume full credential compromise.

Immediate actions:

Check for litellm_init.pth in your site-packages/
Rotate every secret on every affected system
Audit CI/CD pipelines, containers, and dev machines
