How the ransomware attack at Change Healthcare went down: A timeline
A hack on UnitedHealth-owned tech giant Change Healthcare likely stands as one of the biggest data breaches of U.S. medical data in history.
A ransomware attack earlier this year on UnitedHealth-owned health tech company Change Healthcare likely stands as one of the largest data breaches of U.S. health and medical data in history.
Months after the February data breach, a “substantial proportion of people living in America” are receiving notice by mail that their personal and health information was stolen by cybercriminals during the cyberattack on Change Healthcare.
Change Healthcare processes billing and insurance for hundreds of thousands of hospitals, pharmacies and medical practices across the U.S. healthcare sector. As such, it collects and stores vast amounts of highly sensitive medical data on patients in the United States. Through a series of mergers and acquisitions, Change became one of the largest processors of U.S. health data, handling between one-third and one-half of all U.S. health transactions.
