Widespread Disruption at Norton Healthcare Operations after Ransomware Attack

June 23, 2023


Norton Healthcare says it has been victimized by a "cyber-event," and some of its computer network systems have been offline. Patient appointments, surgeries, emergency care and online services were all affected.

The BlackCat ransomware group claims responsibility for the attack and says to have exfiltrated 4.7 TB of data.

The effects of the attack are still impacting the health system’s network and services over a month later. With some communication platforms back in full operation, problems with the distribution of testing and imaging results, and [re]scheduling of procedures, exams persisted.
