Change Healthcare Data Breach Expands to 190 Million Americans

The largest healthcare data breach in U.S. history exposed sensitive medical and personal information, raising serious cybersecurity concerns.

The breach, attributed to the BlackCat ransomware group, initially reported 100 million affected individuals but has now grown to 190 million people.
Compromised data includes Social Security numbers, medical records, insurance details, and other sensitive personal information.
The attack caused widespread disruptions in the healthcare system, affecting pharmacies, doctors, and military health services, leading to significant patient hardships.
UnitedHealth paid a $22 million ransom to recover data, but hackers failed to honor their agreement and later demanded additional payments.
The breach has highlighted systemic cybersecurity vulnerabilities in the healthcare sector, including reliance on outdated systems and lax security measures like the absence of multi-factor authentication.
