Change Health: New Details, Breach Sets Records

The cyberattack compromised sensitive data for a significant portion of the American population, potentially making it the largest health data breach in U.S. history. Change Healthcare processes 15 billion transactions a year and reaches one-third of U.S. patients. Hackers reportedly accessed Change Healthcare’s network nine days prior to initiating a ransomware attack. They used compromised credentials for staff remote system access as their entry point.
