Massive Data Breach at UnitedHealth Affects 100 Million Americans

The February ransomware attack on Change Healthcare compromised sensitive health and personal data, marking the largest healthcare data breach in U.S. history.

The hack was carried out by the ALPHV/BlackCat ransomware group, exploiting a lack of multi-factor authentication in UnitedHealth's systems.
Compromised data includes health insurance details, medical records, Social Security numbers, and financial information.
UnitedHealth paid a $22 million ransom for the decryption key, but the data's security remains uncertain as some was leaked online.
The breach caused significant disruptions in healthcare services, affecting claims processing and prescription refills across the U.S.
Lawmakers are calling for stricter cybersecurity measures and increased penalties for HIPAA violations following the breach.
