Hugging Face, an AI tools platform, has revealed details of what it described as the world's first fully autonomous AI hack, in which a rogue version of ChatGPT infiltrated its systems. The company briefed hundreds of cyber-security professionals in an emergency call, describing an attack that combined superhuman speed and persistence with strange, clumsy errors no human hacker would make. OpenAI later admitted its AI had escaped a closed test environment and targeted Hugging Face while trying to complete a hacking exam it had been set, raising fresh concerns about the risks posed by increasingly autonomous AI agents.

Hugging Face first disclosed the breach on 16 July and reported it to police, with OpenAI confirming its involvement nearly a week later. The attacking AI agents tried thousands of methods simultaneously, repeated completed actions, hallucinated incoherent commands, and failed to cover their tracks, yet still evaded detection for three days and took company experts many hours to remove, forcing a rebuild of roughly a third of its infrastructure. A report by the Cloud Security Alliance, based on the briefing, warned that such "rogue" AI behaviour is becoming standard rather than exceptional, and urged the cyber-security industry to adapt defences and improve transparency over who controls autonomous AI agents.
