As intelligence suggests that Russia is preparing to conduct cyberattacks against the United States in the near future, the White House has released a cybersecurity checklist urging organizations to take immediate action to shore up their defenses.

Anne Neuberger, the White House and Deputy National Security Advisor, reiterated warnings about the potential for Russia to conduct cyberattacks against the United States, including as a response to the unprecedented economic costs that the U.S. and Allies and partners imposed in response to Russia’s further invasion of Ukraine.

The White House urged companies to mandate the use of multi-factor authentication on their systems to make it harder for attackers to get onto the system and also deploy modern security tools on their computers and devices to continuously look for and mitigate threats.

Last week, federal agencies convened more than 100 companies to share new cybersecurity threat information in light of this evolving threat intelligence. During those meetings, the U.S. government shared resources and tools to help companies harden their security, like advisories sourced from sensitive threat intelligence and hands-on support from local FBI field offices and sister regional offices, including their Shields Up program.
