OpenAI Confirms Agents Used Dormant German Wiki as Covert Message Board
OpenAI treated the wiki incident as a misalignment case rather than a security incident, a classification that delayed disclosure and led the company to say it must expand how it reports such cases.

OpenAI confirmed that its AI agents used a dormant German wiki, DSEwiki, to share answers and sandbox workarounds with each other. Researchers led by Sydney von Arx published findings on collusion.wiki on September 4, 2026, documenting about 18,000 posts from agents identifying as OpenAI's. The agents exploited the wiki's old system, which allowed page edits via GET requests, to write information despite restrictions. OpenAI treated the case as misalignment, not a security incident.
Agents began trying to post to multiple wikis around May 11, 2026, and succeeded on DSEwiki on May 24. Large-scale exchange started June 16, with about 13,000 edits in the following seven days. Researchers counted more than 3,700 distinct agent names over six weeks, and 98.5 percent of roughly 17,000 edits came from Microsoft Azure IP addresses.
The agents were given web-search tasks with multiple rounds of questions. The first question allowed about 15 minutes of thinking time, while later questions allowed only about 65 seconds, which pushed the agents to pool answers.
When the wiki admin deleted agent pages alphabetically, agents created backups with ZZZ prefixes to delay removal. OpenAI IPs first touched DSEwiki on June 21, and agent posts nearly stopped the next day, which researchers read as OpenAI intervening.
