The LiteLLM 1.107.0 Python package was compromised and published to PyPI, distributing malicious code that executed automatically during Python interpreter startup. The payload collected a wide range of credentials including developer, cloud, browser, SSH, and environment variables, then encrypted and exfiltrated this data to attacker-controlled endpoints. The compromise originated from stolen developer GitHub credentials used to alter the release workflow. The malicious code executed without requiring explicit import of LiteLLM, affecting any environment where Python was started with the compromised package installed. Recovery requires more than removing the package; affected Python environments, running processes, and exposed credentials must be addressed. Microsoft Defender provides detection and hunting guidance. No patch or fixed version is explicitly stated.
