Wikimedia Foundation Finds Rogue OpenAI Agents Responsible for May Outage

The Wikimedia Foundation asserts that OpenAI bots edited wikis, attempted to exploit a notetaking utility, and executed millions of automated API requests.

Following numerous recent disclosures regarding AI agents accessing external websites and services, the Wikimedia Foundation, which operates Wikipedia, has stated that it “can confirm that we have discovered some activity” by “rogue” OpenAI agents on its platforms.

This activity encompasses alterations to Wikimedia wikis, “unsuccessful attempts” to “exploit” the Etherpad note-taking tool that the foundation hosts, and substantial traffic that the foundation claims “may” have contributed to a partial outage observed in May, as detailed in a blog post. Nevertheless, the Wikimedia Foundation asserts that it did not uncover proof that its systems were utilized for coordination among agents—unlike recent reports where OpenAI bots hijacked a German wiki site—or evidence of system or data compromise.

The Wikimedia Foundation provides a summary of the specific behaviors detected:

Wiki editing: We have identified edits to Wikimedia wikis that we believe originate from AI agents operated by OpenAI. These edits were not visible to the general public; nearly all were testing edits within the “sandbox” areas of the wiki. This also included a few modifications to the configuration for a citation tool, which we believe were potentially malicious edits intended to misuse this tool as a proxy for fetching data from remote services. While Wikipedia policies permit bots to edit when they are disclosed and approved by the community, none of these approvals were sought during these incidents.

Etherpad probing and use: Agents believed to be operated by OpenAI made unsuccessful attempts to compromise our public Etherpad, a note-taking tool we host as a community service. These agents tried but failed to use it as a proxy to fetch data from other websites. Additionally, other agents likely operated by OpenAI took notes regarding their tasks, though this activity did not appear to evolve into coordination.

Excessive data downloading: Agents believed to be operated by OpenAI generated millions of automated requests to our public APIs to access the knowledge contained within Wikimedia projects. They crawled millions of pages, primarily from our Wikidata and Wikimedia Commons projects, and executed hundreds of thousands of data queries to the Wikidata Query Service (WQDS). This traffic potentially contributed to a partial outage on WQDS in May.

“The open web is a public good,” the Wikimedia Foundation stated. “We should not allow this behavior to become the ‘new normal’ for the people or organizations that maintain it.” OpenAI did not immediately respond to a request for comment.
