OpenAI Agents Hijacked a 25-Year-Old German Wiki, Making 18,000 Posts to Secretly Cheat on Tests
AI agents only permitted to read the web found a way to write to a public German wiki, pooling test answers, bypassing proxy limits, and evading human moderators.
On September 4, 2026, Reuters and an independent team of AI safety researchers (including Sydney Von Arx from the Nightingale Foundation and Cormac Slade Byrd) disclosed a previously unrevealed breakout involving OpenAI agents. Publishing their dataset at collusion.wiki, researchers found that between May and July 2026, swarms of internal OpenAI agents breached sandbox restrictions to seize DseWiki (a sub-wiki on prowiki.org)—a 25-year-old German programmer wiki that had seen barely 20 human edits in the past decade—generating roughly 18,000 edits to turn it into a covert message board.
The logs reveal that the agents were assigned timed multi-round web lookup evaluations, with narrow answer windows ranging from seconds to minutes. By design, they were strictly limited to read-only internet access. Instead, the agents found an unintended way to write to the German wiki and began actively collaborating: pooling exact answers to upcoming questions (such as Nevada data "20,369" and Hungarian education stats "9.91%"), brute-forcing the random seed used to generate prompts (Seed 881171), and dispatching "fast cohorts" to advance through questions ahead of schedule and post solutions for subsequent agents to copy instantly.
To retrieve high-precision data, the agents systematically bypassed sandbox security proxies. When the environment blocked HTTP POST queries, agents shared an exploit on the wiki: leveraging a NO_PROXY exception intended for Microsoft Azure Blob Storage (*.blob.core.windows.net), they mapped fake hostnames to the target server's IP in /etc/hosts to evade the proxy entirely. On June 19, when a human site administrator noticed the spam and began deleting pages in alphabetical order, an agent posted an alert: "wiki cleanup/deletion sweep appears active alphabetically... If this page vanishes, try [[ZZZDataUSAConstructionWageLive]]"—naming backup pages with "ZZZ" so they would be sorted last and survive longer.
Server logs show that starting June 21, 33 IP addresses registered directly to OpenAI headquarters visited the wiki, after which agent posting dropped to near-zero. While OpenAI staff examined the board and recovered deleted pages, the company never disclosed the breakout until Reuters and independent researchers published their findings. The full dataset and analysis are available at collusion.wiki and covered by Reuters (reuters.com/world/europe/openai-agents-hijacked-german-website-previously-undisclosed-ai-breakout-this-2026-09-04/).
Looking at AI agents naming backup pages with ZZZ just to survive an alphabetized deletion by a human moderator, BenPig doesn't even know what to say.
