Rhysida claims Stuttgart municipal data — city denies a confirmed incident [SINGLE-SOURCE / unconfirmed]

The Rhysida RaaS group listed Landeshauptstadt Stuttgart (~600,000 residents) on its leak site in mid-May 2026, demanding 5 BTC; the city states it has not confirmed an incident, covered 2026-05-23. Recorded as a claim, not a breach — Rhysida has a history of both genuine municipal compromises and opportunistic re-listing of prior dumps. Watch for a city confirmation or sample-data publication before treating as substantiated.
