Federal legislators confirm February's data breach at UnitedHealth subsidiary Change Healthcare was the largest in the country's history.

A February cyberattack on a UnitedHealth subsidiary compromised the personal data of some one-third of Americans.

UnitedHealth, the largest U.S. health insurance provider, blamed a Russia-based ransomware gang for the huge data breach of U.S. medical data.

Insurance company UnitedHealth Group is confirming a ransomware attack earlier this year affected the private data of over 100 million people. The number was published in the US Department of Health and Human Services Office of Civil Rights (OCR) Breach Report on Thursday, making it the largest healthcare data breach on the list.

Staying safe from hackers is hard enough as it is but even if you take all the necessary precautions, your personal data could still end up being exposed online as the result of a data breach and that’s exactly what just happened to more than 800,000 people.

According to a government report, every year an estimated $60 billion is lost to Medicaid fraud, with much of that traced to stolen medical records.

The breach report from Change comes as data breaches in the healthcare industry affect more Americans and expose sensitive health data. During an interview at the HLTH conference earlier this week, OCR Director Melanie Fontes Rainer said about 140 million people were affected by large breaches in 2023, up from 51 million in 2022.

Insurance administrative services company Landmark Admin warns that a data breach impacts over 800,000 people from a May cyberattack.

The February hack at UnitedHealth's tech unit Change affected the personal information of 100 million people, the U.S. health department's website showed, making it the largest healthcare data breach in the country.
