Intelligence reports indicate that Russia is looking at ways to attack the U.S., so President Joe Biden advised corporations to strengthen their cybersecurity practices.

Almost a month after Russian troops invaded Ukraine, the guidance came.

The president warned about the potential for Russia to conduct malicious cyber activity against the United States. The Administration is repeating warnings based on evolving intelligence that the Russian Government is looking at possible cyberattacks.

The use of multi-factor authentication was included in the White House guidance. The White House advised companies to back up their data, refresh passwords, and keep their devices up to date with the latest security fixes.

Biden said that everyone needed to do their part to meet one of the defining threats of our time.

Anne Neuberger, the U.S. deputy national security advisor for cyber and emerging technology, told reporters at a press conference that they don't know if adversaries will mount an attack on critical infrastructure. Hundreds of companies received classified briefings from the federal government last week.

Neuberger wouldn't name the industries that could be at risk of getting hit, but he said there was some preparation going on.

The company said it suspected it was aimed at customers of the cryptocurrencies. The attacker was not identified by HubSpot.

Last month, Microsoft said it was sharing cyberthreat information with the U.S. government. The company did not attribute the attacks on civilian and military targets in Ukraine to Russia or any other actor.

Ned Price, a spokesman for the State, said that there would be a high price to pay if the Russians were to use their capabilities to target critical infrastructure.

The report was contributed to by CNBC's Christina Wilkie and Amanda Macias.
