Change Healthcare ransomware (2024)
The ALPHV/BlackCat ransomware group breached Change Healthcare, UnitedHealth's billing and claims processing arm that handled roughly 15 billion transactions a year. The outage froze prescriptions and payments at thousands of pharmacies nationwide for weeks.
Prescription processing was down for over a week at many pharmacies; UnitedHealth paid a $22 million ransom.
The breach exposed data on a large share of American patients and triggered federal scrutiny of healthcare cybersecurity.
Shows how one healthcare IT outage can freeze prescriptions for days, the same problem Fenway patients now face.
