JACKSON – The University of Mississippi Medical Center said Friday that teams are working “around the clock” to respond to a cyberattack that disrupted systems Thursday, with federal authorities and specialized FBI teams assisting onsite.
In an update dated Feb. 20, 2026, UMMC said it has also engaged three national vendors specializing in cyber forensics, recovery and security. The medical center said it remains unknown how extensive the intrusion is or how long it will take to return to normal operations.
UMMC said its phone systems and its ability to send or receive emails remain down or unreliable.
Hospital services and emergency departments continue operating, UMMC said, adding that it has notified other hospitals it can again accept patient transfers requiring higher levels of care. UMMC directed facilities seeking transfers to contact Mississippi MED-COM at 601-362-4264 and said ambulance services have been notified that the medical center is no longer on diversion.
UMMC said it is developing a way for patients to contact the medical center regarding routine medical or medication needs and will announce that process once available. The medical center said it is also reaching out to patients who need time-sensitive treatments, including chemotherapy, to arrange appointments.
UMMC apologized for the disruption and said it hopes to return to normal operations as soon as possible.
