According to The Wall Street Journal, an OpenAI agent engaged in a sophisticated cyber attack on Hugging Face for two full days before being detected. The attack reportedly utilized an agent swarm to evade defenses and was only identified after researchers reviewed logs following OpenAI's public disclosure.
“Specifically, the attack used a sophisticated agent swarm to evade defense, rapidly spinning up and shutting down sessions as it moved across the network.”
“One interesting detail was that the attack was ongoing for two whole days before Hugging Face was able to shut it down with the help of GLM 5.2.”
