UnitedHealth Update Reveals Massive Scale of 2024 Change Healthcare Breach: 190 Million Americans Affected
In an update, UnitedHealth Group has confirmed that approximately 190 million Americans were impacted by the February 2024 ransomware attack on its Change Healthcare subsidiary – nearly double the initial estimate of 100 million individuals. This revelation makes it the largest healthcare data breach in U.S. history, affecting well over half of the American population.
The Breach: What Happened
The incident began when the Russian-speaking ransomware group ALPHV/BlackCat gained access to Change Healthcare’s systems using stolen credentials for their Citrix remote access service. Critically, the compromised access point lacked multi-factor authentication protection. Once inside, the attackers:
- Exfiltrated approximately 6 terabytes of sensitive data
- Deployed ransomware across the network
- Forced Change Healthcare to shut down its IT systems
- Disrupted critical healthcare operations nationwide
Impact and Aftermath
The breach’s impact has been far-reaching:
- Stolen data included names, addresses, dates of birth, Social Security numbers, driver’s license numbers, passport numbers, medical records, insurance information, and financial details
- Healthcare providers and pharmacies experienced widespread disruption in claims processing and prescription fulfillment
- Many patients were forced to pay full price for medications when prescription discount cards couldn’t be processed
- UnitedHealth paid a $22 million ransom, but complications arose when BlackCat executed an exit scam
- A second ransomware group, RansomHub, later emerged threatening to leak the stolen data
- Total estimated losses for UnitedHealth are approaching $2.9 billion
