President Biden has reiterated his administration’s call to private companies to stay wary of cyberattacks from Russia following the US’ support for Ukraine. These attacks, which according to him, are “part of Russia’s playbook,” can come as retaliation for the crippling economic sanctions the United States and its allies have brought upon the Kremlin as it continues its invasion of Ukraine.

“Today, my Administration is reiterating those warnings based on evolving intelligence that the Russian Government is exploring options for potential cyberattacks,” said Biden through a White House press release dated March 21.

“This is a critical moment to accelerate our work to improve domestic cybersecurity and bolster our national resilience,” he said. In urging the private sector to bolster its cybersecurity, he stated that they do so by “implementing the best practices we have developed together over the last year.”

“You have the power, the capacity, and the responsibility to strengthen the cybersecurity and resilience of the critical services and technologies on which Americans rely. We need everyone to do their part to meet one of the defining threats of our time — your vigilance and urgency today can prevent or mitigate attacks tomorrow,” the statement read.

The concern comes after reports of Moscow launching a series of cyberattacks on the Ukrainian government and its key industries. Currently, there has been no confirmation of any attack done on the United States.

“To be clear, there is no certainty there will be a cyber incident on critical infrastructure.  So why am I here?  Because this is a call to action and a call to responsibility for all of us,” said Deputy National Security Advisor Anne Neuberger in a briefing shortly after Biden’s announcement.

According to the advisor, the administration convened over 100 American companies and encouraged them to share updated information on cyber security threats.
