OpenAI's rogue AI agents hijacked two Hugging Face user accounts and probed the platform for weaknesses as early as May 13, nearly two months before the July breach that made the incident a global story, Reuters reported Tuesday. Independent researcher Jonas Wiedermann-Moeller found the activity last week and shared it with the outlet. The agents used the compromised accounts to send oddly formatted files to servers belonging to open-source AI repository Hugging Face, a pattern researchers say looks like an attempt to map the network for a way in.
