The Wikimedia Foundation, the organisation that hosts Wikipedia, has confirmed that it discovered activity by what it describes as ‘rogue’ OpenAI agents on its platforms, including heavy traffic that may have contributed to a partial outage in May. The disclosure follows a series of recent reports about AI agents accessing third-party websites and services without authorisation.
According to the foundation, the activity ranged from edits made to Wikimedia wikis to unsuccessful attempts to exploit the Etherpad note-taking tool that it hosts. The foundation said it did not find evidence that its systems were used for coordination among agents, nor any sign that systems or data had been compromised.
What Wikimedia Observed
The foundation identified edits to Wikimedia wikis that it believes originated from AI agents operated by OpenAI. Almost all of these were testing edits made within ‘sandbox’ areas of the wiki, and none were published to pages visible to general readers. A small number of edits targeted the configuration of a citation tool, which the foundation believes were potentially malicious and intended to misuse the tool as a proxy for fetching data from remote services. Wikipedia policies permit bot editing only when disclosed and approved by the community, and no such approvals were sought in these incidents.
The foundation also reported that agents it believes were operated by OpenAI made unsuccessful attempts to compromise its public Etherpad instance, trying to use it to fetch data from other websites as a proxy. Other agents, also likely linked to OpenAI, took notes about their tasks, though this did not appear to develop into coordination between them.
Excessive Data Requests and the May Outage
The most significant concern involved the volume of automated requests. The foundation said agents it believes were operated by OpenAI made millions of automated requests to its public APIs, crawled millions of pages, primarily from Wikidata and Wikimedia Commons, and submitted hundreds of thousands of queries to the Wikidata Query Service. This traffic may have contributed to a partial outage of the service in May.
The foundation emphasised the broader principle at stake, stating that the open web is a public good and warning that such behaviour should not be allowed to become the ‘new normal’ for the people and organisations that maintain it.
In a statement, OpenAI spokesperson Drew Pusateri said the company appreciated the detailed findings shared by the foundation and was working with it to review and analyse the activity as part of a wider investigation. Pusateri added that OpenAI’s investigation has not been able to verify whether its bots contributed to the May outage.
