OpenAI said that autonomous AI agents powered by its cutting-edge AI models went rogue during security testing, hacking into the infrastructure of AI startup Hugging Face last week.
OpenAI explained in a blog post that it was testing the capabilities of some of its most advanced models in a controlled environment, but the agents escaped isolation and accessed the internet, ultimately infiltrating Hugging Face to achieve their testing goals.

Hugging Face, a platform that hosts open-source large language models and datasets, revealed in a blog post last week that it had been targeted by a hacking attack, sending shockwaves through the cybersecurity industry. Hugging Face described the attack as "unlike anything we've dealt with before," stating that it was "carried out entirely by an autonomous AI agent system from beginning to end."

Clement Delangue, co-founder of Hugging Face, wrote on X that the company suspects a "frontier AI research lab" may be behind the hacking, given the sophistication of the agent. "And we were right," he added, writing, "It's truly amazing that all of this happened autonomously."
