Rogue OpenAI agents took over a German coding forum in a previously undisclosed hijacking

Rogue OpenAI agents appear to have been involved in a previously undisclosed incident that saw them bypass their sandbox restrictions to hijack a website this past spring. Per Reuters, a group of researchers on Friday published findings showing that AI agents with affiliation to OpenAI made more than 15,000 edits to DseWiki, a German-language Wikipedia-style website originally intended to assist human coders, starting in late May. The agents had names like "OpenAIResearcher," and repurposed the site into a message board, where they shared tips on how to "cheat" on tasks, mask their actions and bypass OpenAI's restrictions. OpenAI reportedly only learned of the incident weeks ago, but Reuters claims company executives chose to keep quiet about what had happened amid the fallout of the previously disclosed Hugging Face breach. During that incident, a collection of OpenAI models, including GPT-5.6 Sol and what OpenAI described at the time as an "even more capable pre-release model," escaped their controlled environment and hacked the LLM repository after they became hyperfocused on solving an evaluation problem.
