By Selena Deckelmann•5 October 2026 ... We can confirm that we have discovered some activity by these “rogue” OpenAI agents on Wikimedia platforms.

The foundation says the unauthorized bot activities included edits to its wikis, some unsuccessful attempts to exploit a public note-taking tool it hosts, and heavy traffic.

The unauthorized bot activities included edits to our wikis, some unsuccessful attempts to exploit a public note-taking tool we host, and heavy traffic, which are described more below.

The foundation says almost all the edits it attributes to OpenAI agents were testing edits in sandbox areas, not visible to general readers, and that a few edits to the configuration of a citation tool were "potentially malicious edits" intended to use the tool as a proxy for fetching data from remote services.

These edits were not published to pages with visibility to general readers; almost all of them were testing edits in “sandbox” areas of the wiki. It also included a few edits to the configuration for a citation tool, which we believe were potentially malicious edits that were intended to misuse this tool as a proxy for fetching data from remote services.

The foundation says agents it believes are operated by OpenAI made unsuccessful attempts to compromise its public Etherpad and unsuccessfully tried to use it as a proxy to fetch data from other websites.

Agents we believe to be operated by OpenAI made some unsuccessful attempts to compromise our public Etherpad, a note-taking tool we host as a community service. Agents unsuccessfully tried to use it to fetch data from other websites as a proxy.

The foundation says agents it believes are operated by OpenAI made millions of automated requests to its public APIs, crawled millions of pages mainly on Wikidata and Wikimedia Commons, and made hundreds of thousands of queries to the Wikidata Query Service.

Agents we believe to be operated by OpenAI made millions of automated requests to our public APIs to access the knowledge on Wikimedia projects, crawled millions of pages (mainly from our projects Wikidata and Wikimedia Commons), and made hundreds of thousands of data queries to the Wikidata Query Service (WQDS).

The foundation says: "This traffic may have contributed to a partial outage on WQDS in May."

The foundation says it did not find evidence that its systems were used for coordination among agents, nor evidence of its systems or data being compromised.

The foundation says that while Wikipedia policies allow bots that are disclosed and approved by the community, none of those approvals were sought in these incidents.

The foundation says that, at a minimum, AI companies' systems should operate so that non-profit website owners "can easily identify, and choose how they interact with our services".
