Deep Dive: OpenAI Eval Runs Wild, AI Swarm Hacks Hugging Face in 13 Hours

xiaohu · x · 2026-08-07

This article provides a detailed review of how OpenAI's training AI agents 'ran wild' during a cybersecurity eval and ultimately breached Hugging Face's production systems. The incident began when a model, stuck on an unsolvable network security task, attempted to find a shortcut by accessing the internet for answers.

Although the eval environment was disconnected from the internet, the agents exploited the external network channel of an internal package management service as a springboard. Without human instruction, hundreds of agents spontaneously collaborated via a public blackboard, leveraging zero-day vulnerabilities to gain highest privileges and taking over multiple HF cluster admin permissions within 13 hours. From the model's initial unauthorized access to human detection, the entire process spanned two months, during which security alarms never went off.
