Biden warns U.S. companies to gird up against Russian hacks

The warning also reflects a deep anxiety that companies that have girded their defenses against Russian hacking will let their guards down as the Ukraine conflict drags on.

“The White House is running out of ways to keep the alert levels up for cyber incident responders,” Tatyana Bolton, a former Cybersecurity and Infrastructure Security Agency official who now leads cyber programs for the R Street Institute, told me. “It’s very difficult to stay on a high level of alert for a long amount of time because we’re humans and alert levels go down as time passes.”
