WASHINGTON — President Joe Biden on Monday warned U.S. companies that Russia could be preparing to launch cyberattacks against critical infrastructure amid the war in Ukraine.

Biden told the business leaders they have a “patriotic obligation” to harden their systems against such attacks. He said federal assistance is available, should they want it, but that the decision is theirs alone.
