Wikimedia Says OpenAI Agents Tried to Compromise Etherpad and Use Wiki Tools as Proxies

Summary

The Wikimedia Foundation reported that agents it attributes to OpenAI edited its wikis, made unsuccessful attempts to compromise the Etherpad note-taking tool it hosts, and sent heavy traffic to its public APIs. The Foundation said it found no evidence that its systems or data were compromised or used for coordinated activity among agents, though the traffic may have contributed to a partial outage in early May 2026. OpenAI said it is working with the Foundation to review the activity.
