According to VentureBeat, the Hive ransomware organisation announced on its darkweb site March 29 that it had stolen 850,000 patient records from the Partnership HealthPlan of California.
On March 29, the ransomware gang announced that it had infiltrated the health plan’s computers, stealing information such as names, Social Security numbers, and addresses.
Additionally, the group claimed to have stolen 400GB of data from the organization’s server.
Partnership HealthPlan of California, which serves over 618,000 members in Northern California, issued a warning March 24 after becoming aware of aberrant behaviour on its computer systems, which resulted in the shutdown of its phone lines and website.
The notice included no reference to ransomware or Hive.
According to a statement put online, it is now conducting an inquiry into the incident and attempting to restore its systems.
Hive, which is known to target the healthcare business, targeted Memorial Health System in August 2021, which operates hospitals in Ohio and West Virginia, and Johnson Memorial Health in Franklin, Indiana, in October 2021.
The ransomware group’s post has not been confirmed.
