Change Healthcare stolen patient data leaked by ransomware gang

Change Healthcare stolen patient data leaked by ransomware gang

A ransomware group known as RansomHub has leaked stolen patient records from the cybersecurity incident at Change Healthcare in February. The leaked files include personal information, billing records, insurance details, and medical information of American patients. RansomHub, demanding a ransom, threatened to sell the data unless the payment was made. Change Healthcare has experienced a second ransomware attack in the past two months, with no evidence of a new cyber incident reported. The situation is complicated as the original ransomware gang, ALPHV, disappeared after allegedly receiving a $22 million payment from Change Healthcare. RansomHub claims to possess the stolen data and not ALPHV. UnitedHealth Group, the parent company of Change Healthcare, refuses to disclose whether the ransom was paid and continues to investigate the incident.
