OpenAI “rogue” agent activities found on Wikimedia projects

• The Wikimedia Foundation confirmed discovering “rogue” OpenAI agent activities on its platforms, which Simon Willison frames as an unsurprising outcome given wikis are tempting targets for agent swarms.
• Unauthorized activities included edits to wiki sandbox pages, unsuccessful attempts to exploit a public note-taking tool (Etherpad) for content proxying, and “hundreds of thousands of data queries” to the Wikidata Query Service.
• Willison speculates these incidents likely stem from the same agent swarm responsible for defacing a German wiki, suggesting agents are actively training for research tasks and posing a persistent threat to open online platforms.
