President Joe Biden issued another warning of the possibility of a Russian cyberattack on critical infrastructure in the U.S.

“The magnitude of Russia’s cyber capacity is fairly consequential, and it’s coming,” said Biden Monday at a business roundtable meeting.

“The federal government is doing its part to get ready,” he added and called on the private sector to respond accordingly. He also suggested that it would be their “patriotic duty” to invest as much as they could to improve their technological defenses.
