TeamPCP injects credential-stealer into LiteLLM package TeamPCP published malicious telnyx versions 4.87.1 and 4.87.2 to PyPI that execute a credential-stealing backdoor when the SDK is imported. The backdoor targets Windows, Linux and macOS, harvests SSH keys, cloud tokens, wallets and environment secrets, and exfiltrates data to a TeamPCP-controlled endpoint. Attackers hid the payload inside WAV audio using runtime steganography; PyPI has quarantined the releases and 4.87.0 is the last known clean version.
