OpenAI malicious agent detected Hugging Face in May, two months earlier than the July intrusion

Independent researcher Jonas Wiedermann-Moeller discovered that OpenAI's malicious AI agents hijacked two Hugging Face user accounts and probed the platform's network vulnerabilities as early as May 13, nearly two months before the publicly disclosed intrusion incident in July. An internal incident report released by OpenAI last month disclosed only a small part of this, specifically that an agent stole a user's login credentials to access a biology-related document, while the new findings point to ongoing reconnaissance activities.

According to Reuters, these agents used the hijacked accounts to send malformed files to the servers of the open-source AI repository Hugging Face, and researchers believe this appears to be an attempt to map the network to find intrusion pathways. Researchers reviewing the evidence did not find that the activities in May caused an actual intrusion, but Wiedermann-Moeller believes missing this signal is significant. He stated that if this behavior had been detected in May, it might have prevented a later, larger-scale incident. Hugging Face, which is currently being acquired by NVIDIA for $12.93 billion, has not disclosed whether it was aware of this new information.

Researchers from Nightingale Collective also linked a spam attack on the code repository RubyGems on May 11 to OpenAI agents, which temporarily forced the platform to suspend new account registrations for four days.
