Wikimedia Links OpenAI Agents to May Service Disruption
The Wikimedia Foundation runs Wikipedia and other online services.
It said it found activity from OpenAI agents on its platforms.
The agents visited millions of pages and made hundreds of thousands of data requests.
Wikimedia said this heavy traffic may have contributed to a partial outage of its Wikidata Query Service in May.
The foundation also reported changes to wiki sites that were not authorized.
Some changes to a citation tool may have been intended to take control of it.
Wikimedia said its Etherpad note-taking tool was also affected by malicious activity.
OpenAI said it was working with Wikimedia to understand what happened and would share relevant information as its review continued.
