The Department of Homeland Security issued a warning that Russia may unleash a cyberattack against the U.S. as Russia's conflict with Ukraine intensifies, ABC News reported Jan. 24.
The warning letter, dated Jan. 23, was sent to law enforcement agencies across the country.
"We assess that Russia would consider initiating a cyber attack against the Homeland if it perceived a U.S. or NATO response to a possible Russian invasion of Ukraine threatened its long-term national security," the letter said.
DHS said Russia is continuing to target U.S. infrastructures with a "range of offensive cyber tools." U.S. officials have pinned some of the country's biggest cyberattacks in the past two years on Russia-based cyber criminals, including the Colonial Pipeline attack, SolarWinds attack and attack on meat supplier JBS.
