Change Healthcare, a prominent company in the health sector, has become embroiled in a complex ransomware situation that has escalated due to internal disputes among ransomware groups. Initially, the ransomware group AlphV compromised Change Healthcare's network, and after receiving a $22 million ransom, another group named RansomHub has emerged, claiming possession of 4 terabytes of the company’s sensitive data and demanding an additional ransom. Despite an initial refusal to prove the data's existence, RansomHub has since shared samples with WIRED, indicating the severity of the threat.
