When Teiranni Kidd walked into Springhill Medical Center on July 16, 2019, to have her baby, she had no idea the Alabama hospital was deep in the midst of a ransomware attack.

For nearly eight days, computers had been disabled on every floor. A real-time wireless tracker that could locate medical staff around the hospital was down. Years of patient health records were inaccessible. And at the nurses’ desk in the labor and delivery unit, medical staff were cut off from the equipment that monitors fetal heartbeats in the 12 delivery rooms.
