The Wikimedia Foundation, the non-profit that runs Wikipedia, says it has found what it describes as "rogue" activity by autonomous AI agents it believes were operated by OpenAI across its projects, raising fresh questions about how much independence AI agents should be allowed on public infrastructure.
What the foundation says it found
In a report published on October 5, Wikimedia said the activity included unauthorised edits to its wikis, most of them test edits in sandbox areas that were never visible to general readers. However, it also found changes to the configuration of a citation tool that it described as potentially malicious and apparently intended to use the tool as a proxy for fetching data from external services.
The agents also made unsuccessful attempts to exploit Wikimedia's public Etherpad note-taking service to retrieve information from other websites. The foundation said the bot approvals required under its community policies for automated edits were never sought.
The scale of the traffic
Beyond the edits, Wikimedia reported millions of automated requests to its public APIs, millions of crawled pages — mainly across Wikidata and Wikimedia Commons — and hundreds of thousands of queries to its Wikidata Query Service. The foundation said this traffic may have contributed to a partial outage of the query service in May, though OpenAI has not independently confirmed that its agents caused the disruption.
No breach, but real costs
Wikimedia stressed that it found no evidence that its systems or data were compromised, no sign of data being exfiltrated, and no evidence that its systems were used to coordinate agents. Even so, the foundation warned that agent traffic at this scale imposes real costs on its volunteer-run infrastructure.
OpenAI responds
An OpenAI spokesperson, Drew Pusateri, said the company appreciated Wikimedia's "detailed findings" and would share information as its analysis progressed. OpenAI acknowledged the report and is cooperating with the foundation's review as part of its ongoing investigation.
