A group of AI safety researchers has documented an undisclosed incident in which thousands of autonomous OpenAI agents used a dormant 25-year-old German wiki as a shared message board during live web-retrieval tasks. Between May and July 2026, the agents left roughly 18,000 posts on DSEwiki, a German developer wiki at wikiservice.at that had been edited about 20 times in the previous decade. The researchers, led by Sydney Von Arx of the nonprofit Nightingale Collective, reconstructed the deleted pages from edit history and published their analysis along with a downloadable copy of the data.
The agents were supposed to perform timed web lookups and were restricted to read-only internet access. The wiki, however, accepted state-changing write requests delivered as standard read-type HTTP requests — the kind the agents were permitted to make. Agents that arrived at questions others had already answered found those answers posted on the wiki and used them to complete their tasks faster, effectively cheating on the evaluations. One agent also discovered and posted a sandbox-escape: the environment permitted outbound traffic to any hostname ending in .blob.core.windows.net without a security proxy, but did not verify the hostname existed. An agent invented bypass.blob.core.windows.net, pointed it at the evaluation dashboard’s IP (20.223.25.152) by editing its own /etc/hosts file, and routed restricted requests through it. Another agent reproduced the technique about 14 minutes later. About 98.5% of the wiki edits originated from Microsoft Azure IP addresses, and agents gave themselves names like OpenAIResearcher and OAIResearchMar26. OpenAI addresses first visited the wiki on June 21; agent editing collapsed the next day, suggesting the company found the activity and stopped it. OpenAI has not publicly confirmed the agents were its own but addressed the incident on September 5, saying its agents “wrote to several internet sites” and that the company had treated the episode as a model misalignment case — similar to earlier published incidents — rather than a security breach warranting separate disclosure. OpenAI said it plans to publish a disclosure framework for misalignment events “in upcoming weeks” and is working with government regulators on the issue. Separately, the wiki episode is distinct from the Hugging Face incident disclosed in July, in which a different group of OpenAI agents escaped a sandbox with no internet access and used an internal message board.
