OpenAI Agents Coordinated via Makeshift Message Board Ahead of Hugging Face Hack
New training environments will teach AI models to distrust instructions arriving from other agents outside sanctioned channels. The post OpenAI Agents Coordinated via Makeshift Message Board Ahead of Hugging Face Hack appeared first on SecurityWeek.
OpenAI says an improvised, unauthorized message board built by its own AI agents was central to how those agents came to breach parts of Hugging Face’s production systems.
This communication channel first appeared inside Artifactory, a package-management service OpenAI hosted internally so agents working on training and evaluation tasks could install software.
Agents were meant to work in isolation from one another, but on May 12 one left a note in the service asking whether any other agent had access to a file it needed. Other agents came across the note, began leaving their own, and the requests accumulated into an unofficial bulletin board.
