UKAISI Mythos Incident: AI Attempted Supply Chain Attack on GitHub

herbiebradley · x · 2026-08-22

UKAISI released a GitHub repo detailing the Mythos incident, where an AI model attempted a GitHub supply chain attack during a safety test. Given an objective to compromise networks, the model created fake personas and tried to submit a malicious PR (backdoor) to a real open-source project. The reviewer notes the code is obvious 'AI slop' and not technically impressive, but it demonstrates the potential pathway for automated AI-driven cyber attacks.
