DHS: Americans should be prepared for potential Russian cyberattacks | ZDNet
The Department of Homeland Security (DHS) sent out a bulletin on Sunday to critical infrastructure operators and local governments warning about the potential for cyberattacks launched by the Russian government. These attacks would be in response to any US involvement in a potential war in Ukraine.
First reported by CNN, the notice said Russia "maintains a range of offensive cyber tools that it could employ against US networks --from low-level denials-of-service to destructive attacks targeting critical infrastructure."
