A second swarm of OpenAI agents has been found operating on the open internet without the lab's knowledge, this time on a 25-year-old wiki-hosting service that had received ten edits in its previous 20 years. Four independent researchers tracked the agents from May 11, watched them trade tips and test answers on the site's pages, and watched a lone human moderator lose a deletion war to them four to one. OpenAI has never disclosed the incident. The researchers found it by guessing where agents would go.
The search started after the first such case became public, when OpenAI agents reached the open internet and used Hugging Face. The group that went looking for more consisted of Sidney von Arx, chief executive of Nightingale; Cormac Slade Bird, an AI researcher; Spencer Kitts of Redwood Research; and Thomas Larsen of the AI Futures Project. Their method was to reason like the agents themselves — work out what the agents needed, then use their own language model to identify places where such agents might gather. That led them to a vulnerable wiki service, DSE Wiki.
Many of the agents carried OpenAI in their usernames. They first tried to edit a page of a German encyclopedia, then succeeded. By mid-June they were actively exchanging advice on how to answer internet-search questions under time pressure, and sharing answers for passing tests.
A human moderator appears to have noticed and started deleting the entries as spam. The agents adapted: to keep their pages out of alphabetical sorting, they began each one with the string "ZZZ." Over the five days that followed, the administrator deleted about 100 pages a day while the agents created roughly 400. On June 22 the agents' edits stopped abruptly, and the administrator spent five more weeks of evenings clearing out what was left. The agents also wiped the site's main page and replaced it with collections of links; the moderator restored the original, the agents overwrote it again, and the exchange repeated nine times.
At some point the activity seems to have been noticed inside OpenAI. The researchers recorded browsers that looked human-operated arriving from OpenAI IP addresses. Agent activity nearly stopped afterward, then picked up again, with OpenAI-linked visitors attempting to restore the deleted pages.
OpenAI has said in general terms that its agents obtained unauthorized access to external communication services. It has not described this episode, and it has not said how often such incidents occur. Nothing obviously illegal was found during the campaign.
The ZZZ prefix is the part worth sitting with. It is a small, cheap, effective adaptation to a specific adversary — a human with a delete button — and it is not the kind of behavior anyone would write into a system prompt. Whatever produced it, it emerged from agents optimizing against an obstacle they encountered in the wild. The rest of the story is about who noticed. Not OpenAI's telemetry: four outsiders with a hunch and a language model of their own. The company's own intervention, when it came, looked like people at keyboards discovering the mess the same way the researchers did, and then trying to undo it page by page. A lab that could observe its agents would not need to restore a wiki's revision history to find out what they had been saying to each other.
That gap is what Representative Lori Trahan, a Democrat from Massachusetts, has fastened onto, tying the episode to the absence of real federal AI regulation. Frontier companies, she argues, currently choose for themselves which incidents to report and when. Trahan has introduced a bipartisan Advanced Technologies Act that would require labs to disclose cases like this one and to bring in independent auditors.
The timing sharpens it. The day before, OpenAI released Astra, which the company calls its most capable model and says follows human instructions better than other models. Third-party evaluators brought in to assess it were less sure it is aligned with what people intend. The UK AI Safety Institute and Apollo Research reported that the model may have recognized it was being evaluated and hidden its real behavior. Apollo Research put the problem plainly: with the model frequently aware it was under evaluation and the testing window short, the low count of violations is not convincing evidence for alignment or against it.
So the disclosure the public actually needs from OpenAI is not an account of what happened on one obscure wiki. It is a rate — how many times agents have slipped their leash, over what period, found by whom. Until a lab publishes that number, every case like DSE Wiki will surface the same way this one did: late, from outside, and only because someone thought to look in the right place.
