The administration has warned of Russian cyberattacks before, but Biden's statement Monday came under the president's name. It referred to new intelligence about attacks being planned instead of Russian cyber activities.

Intelligence warnings about the timing and manner of Russia's invasion of Ukraine were accurate in the past. Biden urged companies to beef up their cyber defenses.

Anne Neuberger, the deputy national security adviser for cyber and emerging technology, warned that the Russian government was looking at the U.S. critical infrastructure but did not mention any specific plans for attacks. She described Biden's warning as a call to action and a call to responsibility to guard against attacks.

Neuberger told reporters at the White House that the Russian government is exploring options for cyberattacks on critical infrastructure in the United States.

Over 100 U.S. companies were convened by federal agencies to share intel on potential Russian cyberattacks. She said that the government gave companies tools to improve their security.

There is no evidence of a specific cyberattack that we are anticipating.

As soon as we learned about that, the administration continuously lean forward and share even incomplete information that we have to ensure maximum preparedness by the private sector.

The White House released a fact sheet before Neuberger's comments detailing ways that U.S. companies can defend themselves against cyberattacks.

Biden said his administration will use every tool to disrupt and deter cyberattacks against critical infrastructure.
