Overview
- The Feb. 19 ransomware intrusion forced UMMC to take systems offline, blocking electronic medical records and canceling many outpatient services.
- Hospitals and emergency departments stayed open as clinicians used paper charts, command centers and offline workflows to maintain care.
- Patient records access and phone lines were restored before clinics resumed normal operations on March 2, with staff calling to reschedule missed visits.
- Officials said the attackers communicated with the medical center, and the FBI and CISA are assisting with the investigation; no group has claimed responsibility.
- As Mississippi’s primary academic medical center with unique statewide programs, UMMC says it is continuing system recovery and hardening.
