University Medical Center was still experiencing an IT outage Sunday caused by a ransomware attack, which was blamed for forcing the hospital to divert patients to other local hospitals and clinics since last Thursday. The ransomware attack was first reported on Thursday morning, and according to UMC's websites, it is still affecting hospital operations. According to UMC, staff are working around the clock and working with a third-party entity to return to normal operations; however, it does not have a time frame for when that might be.
