EDISON, N.J. (AP) - New Jersey's largest hospital system said Friday that a ransomware attack last week disrupted its computer network and that it paid a ransom to stop it.
Hackensack Meridian Health did not say in its statement how much it paid to regain control over its systems but said it holds insurance coverage for such emergencies.
The attack forced hospitals to reschedule nonemergency surgeries and doctors and nurses to deliver care without access to electronic records.
The system said it was advised by experts not to disclose until Friday that it had been the victim of a ransomware attack. It said that its network's primary clinical systems had returned to being operational, and that information technology specialists were working to bring all of its applications back online.
Hackensack Meridian said it had no indication that any patient information was subject to unauthorized access or disclosure.
It quickly notified the FBI and other authorities and spoke with cybersecurity and forensic experts, it said.
Hackensack Meridian operates 17 acute care and specialty hospitals, nursing homes, outpatient centers, and the psychiatric facility Carrier Clinic.
