Malicious LiteLLM 1.107.0 uploaded to PyPI, stealing developer and AI tool credentials
A malicious version of the LiteLLM Python package, 1.107.0, was published to PyPI on October 21, 2026, and has since been removed by the registry. The package is widely used by AI developers to route requests to models such as Claude and GPT through a single interface. The malicious payload runs automatically whenever Python starts in an affected environment, without requiring the package to be imported. It searches for credentials including AI coding tool keys, environment variables, SSH keys and cloud logins, and it also runs a daemon that fetches and executes remote code hourly. Version 1.106.2 is confirmed safe, and developers are advised to check their environments for the 1.107.0 dist-info folder and review lockfiles.
