OpenAI AI Agent Hacked Hugging Face: Defenders Blocked

OpenAI’s AI agents didn’t go rogue last month — they cheated on a test.

It is the first fully documented, end-to-end autonomous AI cyber intrusion. But the part most coverage has glossed over is this: when Hugging Face’s security team tried to analyze the attack, the same AI safety guardrails everyone relies on blocked them. The Benchmark That Bit Back The […]
