UnitedHealth says Change Healthcare hack affects over 100 million, the largest-ever US healthcare data breach
- More than 100 million individuals had their private health information stolen during the ransomware attack on Change Healthcare in February.
- The U.S. Department of Health and Human Services first reported the updated number on its data breach portal on Thursday.
- UHG began notifying affected individuals in late July, which continued through October.
- The stolen personal data includes personal information, such as names and addresses, dates of birth, phone numbers and email addresses, and government identity documents, including Social Security numbers, driver licenses and passport numbers.
- Change Healthcare is one of the largest handlers of health, medical data and patient records as it processes patient insurance and billing across the U.S. healthcare sector.
- The cyberattack became public on February 21 when Change Healthcare pulled much of its network offline to contain the intruders, causing immediate outages across the U.S. healthcare sector.
- In paying the ransom, Change obtained a copy of the stolen dataset, allowing the company to identify and notify the affected individuals whose information was found in the data.
- Corporate consolidation and poor security blamed for data breach.
- According to its 2023 full-year earnings report, UHG made $22 billion in profit on revenues of $371 billion.
- The Justice Department reportedly began cranking up its investigation into UHG and its potential anticompetitive practices in the months prior to the Change Healthcare hack.
