U.S. cybersecurity officials urged companies to remain on high alert for Russian cyberattacks, reports The Wall Street Journal..

In particular, Jen Easterly, head of the US Infrastructure and Cyber \u200b\u200bSecurity Agency (CISA), noted that the absence of large-scale hacker attacks on Western infrastructure since the beginning of the Russian war against Ukraine should not reduce the vigilance of companies.

“I don’t think we are safe right now given the threats. We know this is part of the RF action plan to use malicious cyberattacks,” Easterly said..

“In fact, we have absolute confidence in the strategic threat,” said Chris Inglis, director of the White House Cybersecurity Office..

He added that public warnings about possible Russian cyberattacks are based on US intelligence assessments that the Russian Federation is a real threat to public infrastructure..

According to the head of the Office of Cybersecurity Robert Joyce, the United States is confident that the attacks were actively planned, only the timing of their implementation is in question..

“According to intelligence data, the threat was and remains real..

The Russians have options that we need to be careful with and are in the process of approving a decision on whether and when to use them,” Joyce said..
