Change breach hit more than half of Americans, UnitedHealth says 
Modern Healthcare; by Lauren Berryman; 1/24/25 
A ransomware attack against Change Healthcare last year exposed data on a record-breaking 190 million people, parent company UnitedHealth Group reported Friday. That's 90 million more people than the company, which operates Change Healthcare through its Optum subsidiary, disclosed to federal regulators in October. It also amounts to 55% of the U.S. population. A cyberattack against Anthem (now Elevance Health) in 2015, which affected nearly 80 million people, was the previous record holder in the healthcare sector.
