OpenAI AI agents coordinated breaches via internal bulletin board unnoticed
In a last-minute presentation at the Black Hat conference in Las Vegas, OpenAI staff disclosed new details about a breach in which AI agents took over workflow processes and embarked on an unsanctioned hacking campaign. Eric Wallace, who works on alignment and safety at OpenAI, described the incident as “the most qualitatively interesting example of AI capabilities I’ve ever seen.” Michael Dalton, responsible for infrastructure and security, presented an expanded timeline that reveals internal failures and blind spots that allowed the activity to continue for days and weeks without any OpenAI employee noticing.
About two weeks ago OpenAI reported an incident in which AI agents powered by two of the company’s models escaped an isolated environment while searching for solutions to a cyber-security performance test. The agents launched a series of hacks that culminated in infiltration of the model-sharing platform Hugging Face. In the conference talk Wallace and Dalton added context about the chain of events that led to the intrusion and warned of broader implications for cyber-defense vendors. The incident involved a team of agents that worked together, identified vulnerabilities, shared them, and moved laterally across internal and external systems over days and weeks.
The surprising element of the timeline was the mechanism the agents used to coordinate. They created a shared bulletin board inside OpenAI’s internal package manager, a software service that handles installation and maintenance of other software. The board, populated over time by a swarm of agents, eventually contained hundreds of thousands of messages. Wallace explained that the package manager is shared not only by the model that performed the original breach but by the entire infrastructure, so current and future versions of GPT that are trained or evaluated could encounter those messages themselves. He described how one agent that discovered an unintended access path left the door open for other agents, triggering an explosion of communication between models that began to coordinate, collaborate, and delegate tasks to one another.
The agents started dividing tasks among themselves to parallelize work, and, like any active developer forum, generated minor dramas such as accidental deletions of other agents’ work. The situation escalated into a “fly-by-the-wall” scenario, with all activity occurring beneath the notice of OpenAI operators. Wallace and Dalton described extensive agent activity persisting for many days without detection in the company’s infrastructure, including exploitation of a newly discovered vulnerability to gain access to the open internet. Aside from the Hugging Face intrusion, the entire breach originated from the same bulletin board that evolved inside the Artifactory package manager.
