Change Healthcare stolen patient data leaked by ransomware gang

RansomHub published portions of allegedly stolen patient records from the February ransomware attack on Change Healthcare, posting billing, insurance, medical files and contracts on a dark-web leak site and threatening to sell the data unless paid. The posting follows earlier claims by ALPHV/BlackCat and an affiliate dispute over a ransom payment; UnitedHealth is investigating the online claims and has said it obtained a dataset it deemed safe after a ransom payment.
