The Python AI gateway library LiteLLM, with a monthly download rate of 97 million, has been compromised in a PyPI supply chain attack, according to 23pds, the Chief Information Security Officer at SlowMist. Attackers can exploit the library by executing the 'pip install litellm' command, enabling them to steal sensitive information from users' devices. The compromised data includes SSH keys, cloud service credentials (AWS, GCP, Azure), Kubernetes configuration files, Git credentials, API keys from environment variables, shell history, cryptocurrency wallet information, and database passwords. Users are advised to exercise caution and verify the integrity of their installations.
