University of Mississippi Medical Center Ransomware Attack Disrupts Epic EHR and Forces Statewide Clinic Closures

The University of Mississippi Medical Center (UMMC) reported a ransomware attack that knocked multiple IT systems offline, including access to its Epic electronic health record (EHR) platform, triggering the organization’s emergency operations plan. The disruption forced UMMC to close all 35 clinics statewide and cancel outpatient, elective, and clinic procedures, while hospital and emergency services remained open under contingency operations.

UMMC stated the attackers have been in communication and that it is working with external specialists and law enforcement; the FBI is investigating and warned the duration of the outage was unknown at the time of reporting. Separate reporting also described a different municipal incident in Meriden, Connecticut, where officials took city internet services and public Wi‑Fi offline after an attempted disruption; emergency services were reported as unaffected and the city said it would conduct a comprehensive review before restoring service.
