UnitedHealth Group CEO Andrew Witty faced criticism from legislators over a cyberattack on subsidiary Change Healthcare during two Congressional hearings. The attack disrupted the healthcare sector and compromised the data of a third of U.S. individuals. Witty revealed that the breach occurred due to a lack of multifactor authentication and confirmed that UnitedHealth paid a $22 million ransom in Bitcoin. Some lawmakers questioned whether UnitedHealth's size made it a high-risk target for cybercriminals and expressed concerns about the company's market power in the healthcare industry. Witty assured that UnitedHealth's size and resources could help the firm recover from the attack.
