On Monday, President Biden warned U.S. companies to be on guard against Russian cyberattacks, citing intelligence as a call to action.

"I have previously warned about the potential that Russia could conduct malicious cyber activity against the United States, including as a response to the unprecedented economic costs we've imposed on Russia alongside our allies and partners. It's part of Russia's playbook," Biden said in a statement on Monday.

"Today, my Administration is reiterating those warnings based on evolving intelligence that the Russian Government is exploring options for potential cyberattacks."
