Ransomware Gangs Claim to Have Attacked Health Plan and Healthcare Provider

Partnership Health Plan of California Getting back from Alleged Ransomware Attack

The nonprofit managed care health plan based in Fairfield, CA, Partnership Health Plan of California (PHC), experienced a cyberattack that resulted in the shut down of its IT systems for more than a week. On March 21, 2022, PHC began alerting regional healthcare clinics about the disruption of its IT systems, its website, and phone lines, and that efforts were in the process to re-establish its systems. A schedule for when IT systems would probably be back was not provided.

PHC didn’t mention in its notices what triggered the outage, however, it seems like a ransomware attack brought on by the Hive ransomware gang. The Hive ransomware gang claimed responsibility for the cyberattack as stated on its clear web and dark web pages and stated 400 gigabytes of data had been exfiltrated from PHC systems that contained 850,000 unique records of name, addresses, SSNs, dates of birth, and other data. That claim has since been deleted.

PHC has not confirmed whether ransomware was employed and the level to which plan members’ information was affected. PHC has about 618,000 health plan members within Northern California. The Hive ransomware group is identified to target the healthcare industry, having formerly performed ransomware attacks on Johnson Memorial Health and Memorial Health System last year.
