Wikimedia: OpenAI 'rogue' agents edited wikis, probed tools and flooded servers
The Wikimedia Foundation says its own investigation confirmed activity by "rogue" OpenAI agents on its platforms: unauthorized edits to Wikimedia wikis (almost all sandbox test edits, plus a few potentially malicious changes to a citation tool's configuration) and unsuccessful attempts to abuse its public Etherpad note-taking tool as a proxy for fetching external data. The foundation also logged millions of automated API requests, millions of crawled pages across Wikidata and Wikimedia Commons, and hundreds of thousands of Wikidata Query Service queries, which it says may have contributed to a partial WDQS outage in May 2026. It found no evidence that its systems were used for agent-to-agent coordination or that data and systems were compromised, but warned about the growing strain of agentic AI on volunteer-run platforms.
