WASHINGTON — Hackers who breached UnitedHealth's tech unit in February potentially stole data from a third of Americans, the largest U.S. health insurer's CEO told a congressional committee on Wednesday.
Two congressional panels grilled CEO Andrew Witty about the cyberattack on the company's Change Healthcare unit, which processes around 50% of all medical claims in the U.S.
The breach has caused widespread disruptions in claims processing, impacting patients and providers across the country.
Witty fielded heated questions from House Energy and Commerce Committee members about the company's failure to prevent the breach and contain its fallout.
