UMMC Ransomware Attack Shuts Clinics and Delays Surgeries in Mississippi

Last Updated: February 24, 2026By

Ransomware Attack Impact on Mississippi Clinics

A recent ransomware attack has significantly disrupted healthcare services at the University of Mississippi Medical Center (UMMC), forcing the closure of multiple clinics and delaying elective surgeries. To protect integrity, UMMC switched to manual processes, temporarily shutting down their digital systems as investigators work to restore operations.

Inside the UMMC System Outage

Electronic health records and communication networks were offline to safeguard clinical information. This has impacted all 35 clinics across Mississippi, stopping non-essential procedures and switching staff to old-fashioned paper documentation. This outage has posed a challenge to maintaining efficiency while prioritizing safety.

Patient Care Disruptions Across Mississippi

With centralized services down, community clinics have faced significant disruption, including delayed tests and rescheduled procedures. Though emergency services continue, manual processes lead to slower operations, urging patients to bring essential documents to ensure efficiency.

Investigation and Cybersecurity Awareness

UMMC is cooperating with federal agencies like the FBI. The attack reflects a wider trend of healthcare vulnerabilities to cyber threats, spotlighting the need for enhanced security measures. Healthcare remains a prime target, and repeated warnings highlight the risk to patient care.

Hospital Vulnerabilities and Cybersecurity Measures

The complexity of healthcare systems makes them vulnerable, and updating older systems is challenging. Network segmentation, multifactor authentication, and regular downtime drills are essential to safeguard against attacks. Financial constraints often hinder progress in these critical areas.

Advice for Patients Amidst the Outage

Patients should check UMMC’s updates for rescheduling, and carry medical details for future visits. If concerned about data breaches, consider fraud alerts and monitoring services. Continue to seek emergency care when needed, as hospitals can still provide essential services.

The ongoing situation underscores the importance of robust cybersecurity to safeguard patient safety and maintain care continuity during digital disruptions.
