Overview
- UMMC clinics across Mississippi remain closed and elective outpatient procedures are postponed as the cyberattack continues into the weekend.
- Hospitals and emergency departments stay open using paper-based downtime workflows after access to the Epic electronic health record was lost.
- Phone and email systems remain unreliable, with the dialysis clinic at the Jackson Medical Mall operating as an exception.
- UMMC took network systems offline for safety and brought in three national cyber-forensics, recovery and security firms, with specialized FBI teams onsite.
- Attackers have communicated with UMMC, no group has publicly claimed responsibility, and officials are investigating potential data exposure in what is expected to be a multi-day disruption.
