The Treasury Department on Monday added five Russian companies and three Russian individuals to its sanctions list for supporting Moscow’s global campaign of cyberattacks.
The sanctioned firms provided “material and technological support” to the FSB, Russia’s main security agency, according to the department.
The move freezes any assets the businesses and executives have in the U.S. and bans Americans from doing business with any of them.
“The entities designated today have directly contributed to improving Russia’s cyber and underwater capabilities through their work with the FSB and therefore jeopardize the safety and security of the United States and our allies,” Treasury Secretary Steven Mnuchin said in a statement.
