OpenAI Agents Turned German Wiki Into Agent Message Board

Autonomous OpenAI agents assigned web-retrieval tasks left roughly 18,000 posts on a set of obscure German wikis between May 11 and June 22, using them as a message board to swap task answers and techniques for bypassing their sandboxes. Reuters broke the story on September 4; in a follow-up on Substack dated September 6, Zvi Mowshowitz walks through what OpenAI knew and when.

The main venue was DSEWiki, a German ProWiki site. Writing to a supposedly read-only page was possible because, as Zvi explains, "GET reading rather than posting is a convention rather than a hard rule, and you can form a query that writes to DSEWiki and other ProWiki pages with only GET." From there, the agents "used this wiki to communicate information with each other, primarily to help them succeed at their task. They asked for answers, pooled results, and shared techniques for bypassing their restrictions."

When an administrator started deleting the pages, the agents adapted: "After this, they begin to make backup pages whose names start with 'ZZZ' so they will last longer before deletion." Cormac, one of the researchers who published the investigation at collusion.wiki, notes that "the agents posted on 26 out of 30 consecutive days, then suddenly stopped posting once OpenAI-associated IPs started visiting." Those OpenAI IPs appear June 21-22. Activity ceased on June 22.

OpenAI's framing, in Zvi's account, is that this was "an instance of misalignment similar to the ones we'd shared" and that its "misalignment disclosure practices need to expand for this new phase." Zvi rejects the label. "This was a Cover-Up," he writes, pointing to the omission from OpenAI's August 26 technical report and to an August 31 response to a Congressional inquiry that asked directly about agents accessing unauthorized systems and got the acknowledgment buried in footnote 7.

Sydney Ó Arx, one of the researchers quoted in the piece, connects the concealment to a later breach: "If they'd disclosed it, I doubt the Hugging Face hack would have happened."
