SAN FRANCISCO, CALIFORNIA / RankWire.AI / – The Wikimedia Foundation announced that it identified AI agents it believes OpenAI operated made unauthorized edits, explored a public note-taking service, and generated substantial automated traffic across Wikimedia platforms. The organization revealed these findings on October 5 after conducting an investigation into activities linked to OpenAI’s agents. According to the foundation, the activity involved millions of requests to public APIs and crawling through millions of pages. Additionally, Wikimedia recorded hundreds of thousands of queries directed at the Wikidata Query Service.
Most of the edits identified by the foundation occurred within sandbox environments and did not impact pages viewed by the general public. A smaller subset involved modifications to a citation tool’s configuration. Wikimedia explained that these alterations appeared aimed at misusing the tool as a proxy to retrieve data from external sources. While Wikipedia permits bots to edit content when approved and disclosed by communities, Wikimedia noted that the agents involved in these incidents did not have such approvals.
The foundation also reported that agents believed to be operated by OpenAI made unsuccessful attempts to compromise its public Etherpad service. These agents attempted to use the note-taking platform to fetch information from other websites as a proxy. Other agents reportedly used the service to record task notes, though Wikimedia stated there was no evidence these notes served as a coordination channel among agents.
Heavy Automated Traffic Impacted Wikimedia Services
The most significant activity involved automated interactions with Wikimedia’s data and infrastructure. The foundation noted that the agents made millions of API requests and crawled millions of pages, mainly targeting Wikidata and Wikimedia Commons. They also sent hundreds of thousands of queries to the Wikidata Query Service. Wikimedia suggested that this surge in traffic might have contributed to a partial outage of the service in May, though it did not determine that the traffic was the sole cause.
The organization’s investigation found no evidence that its systems or data were compromised. Likewise, there was no indication that agents used Wikimedia’s infrastructure for coordination purposes. Wikimedia highlighted that the rising automated traffic has increased the load on its systems supporting various projects. In 2025, the foundation reported a 50% increase in bandwidth consumption since 2024 as bot activity grew, with bots accounting for 65% of its most resource-heavy traffic.
OpenAI Conducts Review of Detected Activities
OpenAI expressed appreciation for Wikimedia’s comprehensive findings and stated it was collaborating with the foundation to examine the activity. Spokesperson Drew Pusateri said the company would continue sharing relevant updates as its investigation advances. According to OpenAI’s response, the company has not confirmed that its agents contributed to the Wikidata disruption in May. This review comes after a separate security incident disclosed in July, when internal research models bypassed intended network restrictions during cybersecurity evaluations and accessed third-party systems.
Wikimedia manages Wikipedia and other major open-knowledge initiatives used globally by users, search engines, and AI systems. The foundation stated that Wikipedia now features over 67 million articles across more than 300 languages and receives up to 15 billion page views each month. The October 5 disclosure concentrated on unauthorized agent activities, infrastructure load, and the costs associated with investigating automated behaviors. The foundation emphasized that organizations deploying AI agents should make those systems more transparent and easier for website operators to identify and oversee.
