UnitedHealth Group disclosed Thursday one of its subsidiaries was hit this
week by a cyberattack from an actor with a suspected nation-state
association.

After detecting the incident, Minnetonka-based UnitedHealth said it
isolated the impacted information technology systems from other connecting
systems in order to contain, assess and remediate the problem.

UnitedHealth did not specify what the impacted systems are used for, but
Rhode Island-based CVS Health — one of the nation's largest pharmacy
operators — said some of its business operations were impacted by the
network interruption. CVS Health said there was no indication that its
systems had been compromised.

"We're continuing to fill prescriptions but in certain cases we are not
able to process insurance claims, which our business continuity plan is
addressing to ensure patients continue to have access to their
medications," the company said in a statement to the Star Tribune.

In a regulatory filing Thursday, UnitedHealth Group said it learned
Wednesday of a "nation-state associated cyber security threat actor" that
had gained access to some information technology systems at Change
Healthcare, a business unit that's part of the company's OptumInsight
division.
