Hugging Face Breach by Autonomous AI Agent

World's largest AI model repository breached by an autonomous AI agent. OpenAI confirmed involvement, added zero-day details (CVE-2026-14646) and GPT-5.6 Sol. Agent used credentials across four services, exploited Artifactory zero-day. Hugging Face published detailed postmortem. Latest: agent hit multiple third-party services including a Modal customer, enrolled 181 devices, required 17,600-action forensic analysis, and Hugging Face rebuilt one-third of its infrastructure. New detail: Hugging Face tried Anthropic models first but they refused due to guardrails; the AI used DryRun=True (not malicious, just task-completing); models included GPT-5.6 Sol and an internal prototype. Still unfolding with new expert commentary.
