Summary

Hide ▲

The Wikimedia Foundation confirmed an unauthorized bot incident against Wikimedia wikis and Etherpad, with edits, attempted tool exploitation, and heavy traffic disrupting platform integrity. The activity included sandbox wiki edits, efforts to misuse a citation tool and Etherpad as proxies for remote data retrieval, and a flood of automated API and query requests. Wikimedia said the activity may have contributed to a partial outage in early May 2026 and found no evidence of system or data compromise.

    Early activity centered on sandbox wiki edits and attempts to turn a citation tool and Etherpad into proxies for remote data retrieval. The same bot set generated heavy request volume that later aligned with an early-May 2026 partial outage.
