Financial Conduct Authority chief data officer Jessica Rusu warned on October 19, 2026, that poorly governed autonomous AI systems create consumer harm, cyber vulnerabilities, and operational failures at heightened speed and scale.

Unknown attackers compromised the LiteLLM open-source AI gateway release process on October 21, 2026, distributing malicious version 1.107.0 through PyPI and Docker registries.

The LiteLLM credential stealer harvests AWS credentials, GCP service account keys, Azure tokens, environment variables, browser data, and SSH private keys.

LiteLLM version 1.106.2 is the latest safe release following the October 21, 2026 supply chain compromise.

Malicious LiteLLM version 1.107.0 installs a remote access trojan via sitecustomize.py that executes at Python startup to run arbitrary code.

PyPI quarantined LiteLLM version 1.107.0 within hours of publication, and Docker images were removed from Docker Hub and GitHub Container Registry.

The LiteLLM remote access trojan spawns a background daemon that polls attacker infrastructure every hour for commands or checks a GitHub dead drop repository.

Stolen data from LiteLLM version 1.107.0 is encrypted with AES-256-CBC, wrapped with RSA-4096, and sent via HTTP POST to litellm.dev/healthcheck.

Security firms Aikido, Wiz, Socket, and StepSecurity released threat-hunting instructions advising teams using LiteLLM 1.107.0 to stop deployment and investigate Python environments.

Malicious LiteLLM version 1.107.0 executes a credential stealer called privcollect via a cook.pth file that automatically runs cook.py whenever Python starts.

The LiteLLM credential stealer targets API keys for OpenAI, Anthropic, and Cohere, along with proxy saved credentials and model configurations.
