    The Wikimedia Foundation says it discovered "rogue" OpenAI agent activity on its platforms.

    • The unauthorized activities include wiki edits and significant traffic.

    • A public note-taking tool hosted by Wikimedia was the target of unsuccessful exploitation attempts.

    • The Wikidata Query Service received "hundreds of thousands of data requests".

    • According to Simon Willison, most of it probably came from a swarm of agents similar to the one that degraded a German wiki.
