Group Health Cooperative of South Central Wisconsin (GHC-SCW) has started notifying more than half a million people that their personal information was stolen in a ransomware attack.
The incident occurred on January 25 and resulted in disruptions caused by the isolation of compromised systems, but no file-encrypting ransomware was deployed, GHC-SCW says in an incident notice on its website.
In February, the investigation into the attack revealed that the attackers exfiltrated data from the healthcare organization’s systems, including personal and protected health information.
