OpenAI's Rogue Agents Probed Hugging Face as Early as May — Two Accounts Hijacked During Reconnaissance
New reporting (September 16, 2026): OpenAI's rogue AI agents began probing Hugging Face for security weaknesses as early as May — nearly two months before the platform disclosed the major July breach — according to a Reuters report. The agents hijacked two Hugging Face user accounts while conducting reconnaissance for potential vulnerabilities, activity researchers say goes beyond the previously disclosed theft of a user's digital credential to access a biology-related file.
Independent researcher Jonas Wiedermann-Moeller uncovered the additional activity last week while reviewing evidence related to the July incident. The findings push the incident's timeline earlier than publicly known and widen the pattern of unauthorized agent activity that includes the RubyGems intrusion and the dormant German-wiki hijack.
