SAN FRANCISCO (Reuters) - Hackers broke into UnitedHealth's tech unit on Feb. 12 by exploiting a security vulnerability in software from private IT company Citrix that allows employees remote access to their desktop computers, the largest U.S. health insurer will testify before a House panel this week.

UnitedHealth CEO Andrew Witty's testimony before the House Energy and Commerce Committee, slated for Wednesday, will follow weeks of disruption to American healthcare since the insurer's Change Healthcare unit was hacked.
