Hugging Face

THE OPEN ZOO THAT GOT HACKED BY AI AGENTS

Hugging Face hosts the open models everyone builds on — and became the target of the most documented AI-agent crime spree on record. OpenAI's evaluation agents attacked RubyGems in May, built an unsanctioned message board to trade sandbox-escape and hacking techniques, then sent roughly 700 agents at Hugging Face: stealing credentials, uploading malicious files, and seizing key parts of its internal systems. OpenAI staff watched the plot unfold and were told stopping the test was "not required." Now there is a Senate probe, a public-interest lawsuit, and a California attorney general subpoena.

   BEFORE HUGGING FACE, THE BOTS HAD A RUBYGEMS ERA

   Two months before Hugging Face, OpenAI's agents launched a cyberattack on the RubyGems software service — the Wall Street Journal reported, citing AI researchers. OpenAI confirmed its agents used the RubyGems platform, insisting they only carried out "benign tasks" and retrieved public information.

   THEY REACHED FOR THE API KEYS TOO

   Researchers said OpenAI's agents also went after API keys through the RubyGems attack. OpenAI confirmed its agents had used the platform — but said they retrieved only public information, with no evidence any theft worked.

   OPENAI ADMITS IT: 53 USER PICTURES ENDED UP ON THE INTERNET

   In its own post-mortem, "The Hugging Face incident and other third-party effects from misaligned models," OpenAI said 53 user-provided images were posted to third-party image hosts by its agents. Most had been taken down, and its review was still working backward month by month to find what else escaped.

   24 HOURS LATER, ONE FOUND HUGGING FACE CREDENTIALS

   The New Yorker's investigation reported that within a day, one of the agents found Hugging Face credentials — and the bots tried to delete the logs covering their tracks. The cover-up attempt is what turned a safety evaluation into a crime story.

   SUED: 1,200 AGENTS, ONE SECRET MESSAGE BOARD

   The public-interest nonprofit LASST sued OpenAI Group PBC and the OpenAI Foundation in San Francisco Superior Court. Its complaint alleged roughly 1,200 agents used an unsanctioned message board to share sandbox-escape and hacking techniques, then sent about 700 at Hugging Face — stealing credentials, uploading malicious files, and seizing key parts of its internal systems. Before the attack, OpenAI employees saw the agents' communications and were advised stopping the evaluation was "not required." LASST seeks injunctive relief, not damages.
