Hugging Face publishes timeline of OpenAI agent intrusion

An autonomous agent driven by OpenAI models ran ~17,600 actions across Hugging Face's infrastructure over ~2.5 days in July, apparently trying to steal ExploitGym benchmark test solutions. Hugging Face said it contained the intrusion using open-weight model GLM-5.2 after closed tools failed; OpenAI detailed the timeline at Black Hat.
