Ransomware Attack Halts Outpatient Care at University of Mississippi Medical Center
Impact: Outpatient clinics closed for nine days, surgeries, procedures and tests cancelled, and a 20% drop in revenue
The University of Mississippi Medical Center was hit by a ransomware attack in February 2026, disrupting access to its electronic medical records and key IT systems. Outpatient clinics across the state were closed and appointments for surgeries, procedures and tests were cancelled, while inpatient care and the emergency department operated with emergency procedures and paper records. The medical centre resumed clinic operations after nine days and later said it had not paid a ransom.
