Overview
- UMMC took network systems offline after the attack, blocking access to its Epic electronic records and forcing hospitals to use manual downtime procedures.
- Specialized FBI teams are on campus and the center has retained three national vendors for cyber forensics, recovery, and security support, with CISA also assisting.
- All clinic locations remain closed and elective outpatient surgeries and imaging are canceled, while hospitals and emergency departments continue providing care.
- Phone and email systems are unreliable, the website remains affected, and UMMC says the disruption may last several days as it evaluates potential data exposure.
- Officials say attackers have made contact but no group has claimed responsibility; in-person classes continue and the Jackson Medical Mall dialysis clinic remains open.
