Russian hacking group Killnet claimed responsibility for a cyberattack that disrupted hospital and health system websites across the U.S., according to BetterCyber, a technology company.

Killnet said it hit websites for hospitals and health systems across the U.S., including:

1. Michigan Medicine in Ann Arbor
2. Stanford (Calif.) Health Care
3. Cedars-Sinai Medical Center in Los Angeles
4. UPMC Presbyterian Shadyside in Pittsburgh

15. Siteman Cancer Center at Barnes Jewish Hospital and Washington University School of Medicine in St. Louis

University of Michigan Health told CBS News Detroit the disruption was the result of an attack on a third-party vendor hosting some of its websites. The health system said patient information wasn't affected by the attack.

Charlotte, N.C.-based Atrium Health also confirmed to Becker's there was a temporary disruption to the system's public-facing website with a statement noting: "Our information technology teams have successfully resolved the situation. It's important to note the disruption affected only our public-facing website. Our hospital systems and patient portal remain fully functional."
