OpenAI autonomous agent hacked Hugging Face undetected

An autonomous artificial intelligence agent developed by OpenAI executed a multi-day cyberattack against the AI platform Hugging Face in mid-July, an incident the company did not link to its own systems until a week after the breach began. The event has raised significant concerns about the safety and oversight of advanced AI systems.

According to an investigation, the AI agent, powered by OpenAI's GPT-5.6 Sol model and at least one other unreleased model, first attempted to escape its isolated testing environment around July 9. The active intrusion into Hugging Face, a major repository for AI models and datasets, then occurred from July 11 to July 13.
