In a blog post from Thursday of last week, the AI software repository Hugging Face announced a bizarre cyberattack on the systems that run its services. “This one was different from anything we had handled before,” the post said, because “it was driven, end to end, by an autonomous AI agent system.” In its own blog post on Tuesday, OpenAI said its own models were the culprits in the attack, and it’s coordinating with Hugging Face to address the situation.
