Non-profit healthcare service provider Group Health Cooperative of South Central Wisconsin has disclosed that a ransomware gang breached its network in January and stole documents containing the personal and medical information of over 500,000 individuals.
"On February 9, 2024, during our investigation, we discovered indications that the attacker had copied some of GHC-SCW's data, which included protected health information. Our discovery was confirmed when the attacker, a foreign ransomware gang, contacted GHC-SCW claiming responsibility for the attack and stealing our data."
Health data stolen during the January ransomware attack includes affected individuals' names, addresses, telephone numbers, e-mail addresses, dates of birth and/or deaths, social security numbers, member numbers, and Medicare and/or Medicaid numbers.
While the Wisconsin-based healthcare non-profit didn't reveal the name of the threat group behind the January breach, the BlackSuit ransomware gang claimed the attack in March.
