Kevin Collier reports:
A major hospital chain has been hit by what appears to be one of the largest medical cyberattacks in United States history.
Computer systems for Universal Health Services, which has more than 400 locations, primarily in the U.S., began to fail over the weekend, and some hospitals have had to resort to filing patient information with pen and paper, according to multiple people familiar with the situation.
From what BleepingComputer learned, it sounds like a Ryuk attack.
