A cyberattack on a unit affiliated with UnitedHealthcare, the nation’s largest insurer, has disrupted drug prescription orders at thousands of pharmacies for nearly a week.
The assault on the unit, Change Healthcare, a division of United’s Optum, was discovered last Wednesday.
The attack appeared to be by a foreign country, according to two senior federal law enforcement officials, who expressed alarm at the extent of the disruption on Monday.
UnitedHealth Group, the conglomerate, said in a federal filing that it had been forced to disconnect some of Change Healthcare’s vast digital network from its clients, and as of Monday, had not been able to restore all of those services.
The company was acquired by UnitedHealth Group for $13 billion in 2022.
