After a cyberattack on February 21 disrupted U.S. healthcare operations, UnitedHealth's CEO Andrew Witty was criticized for the company's response. The attack on Change, a crucial digital link between health insurers and medical providers, prevented patients from filling prescriptions and stalled payments to healthcare providers. Witty, summoned by Congress, admitted to security lapses and apologized for the disruptions and concerns over private health data security.
