UnitedHealth recently confirmed that over 100 million individuals' healthcare and personal data were exposed in a February ransomware attack on its subsidiary, Change Healthcare. CEO Andrew Witty previously testified that about one-third of Americans might be affected. The data stolen includes sensitive details such as health insurance information, medical records, Social Security numbers, and financial information. The attack was orchestrated by the BlackCat ransomware group and hindered claim filings and pharmacy operations. UnitedHealth reportedly paid a $22 million ransom for data decryption.
