Change Healthcare faces another ransomware threat—and it looks credible

Ransomware group AlphV claimed credit for encrypting the network of healthcare company Change Healthcare and demanded a ransom. The company apparently paid the ransom, but now another ransomware group called RansomHub claims to have the stolen data and is demanding their own ransom payment. RansomHub has threatened to sell the data if Change Healthcare doesn't pay up. The authenticity of RansomHub's claims hasn't been confirmed, but they provided screenshots of patient records and contracts as proof. This incident highlights the risks of trusting ransomware groups and the possible fallout even after a ransom is paid.

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.

Health care giant comes clean about recent hack and paid ransom

Change Healthcare recently experienced a ransomware attack that disrupted the US prescription market for two weeks. The attack was made possible through a compromised account that did not have multifactor authentication (MFA) in place. Hackers gained access to the account and moved within the systems before exfiltrating data. The breach started on February 12, and after remaining undetected for nine days, the attackers deployed ransomware, forcing the company to rebuild its entire IT infrastructure. The company paid a ransom of $22 million to the attackers, but they failed to destroy the stolen data as promised. Change Healthcare has since restored its systems, with payment processing at 86% of pre-incident levels.

Security Bite: Ransomware payments hit record $1.1 billion in 2023 despite previous year’s decline

Ransomware payments reached a record high of $1.1 billion in 2023, almost doubling the previous year's total. Large institutions, hospitals, schools, and government agencies were targeted by intensified operations from ransomware actors. The number of ransomware incidents in hospitals and K-12 schools significantly increased as well. The decrease in ransomware activity in 2022 was attributed to the Russian-Ukrainian conflict shifting the focus of threat actors. The emergence of new ransomware variants and the rise of ransomware-as-a-service indicate a growing threat in the cybersecurity landscape.
