UnitedHealth Group confirmed that a February ransomware attack affected over 100 million individuals, marking it as the largest healthcare data breach reported by the OCR.
The attack, claimed by the hacker group Blackcat, disrupted healthcare processing for weeks and involved unauthorized access obtained via stolen credentials.
Stolen data includes health insurance details, medical records, and personal information such as Social Security numbers, highlighting the severe implications of the breach.
CEO Andrew Witty indicated the breach occurred due to inadequate security measures, specifically the absence of multifactor authentication on the Citrix remote access service.
