On February 9, the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC), in coordination with the UK, announced sanctions against seven individuals who allegedly are involved in a Russia-based cybercrime gang and are associated with the development or deployment of a range of ransomware strains designed to steal financial data. (See also UK’s announcement here.) The sanctions, taken pursuant to Executive Order (E.O.) 13694 as amended by E.O. 13757, represent the first sanctions of their kind for the UK, and come as a result of a partnership between OFAC and the U.K.’s Foreign, Commonwealth, and Development Office, the UK National Crime Agency, and His Majesty’s Treasury—all of which serve to disrupt Russian cybercrime and ransomware. “Cyber criminals, particularly those based in Russia, seek to attack critical infrastructure, target U.S. businesses, and exploit the international financial system,” Treasury Under Secretary Brian E. Nelson said in the announcement, stressing that “international cooperation is key to addressing Russian cybercrime.” Referring to an action taken by FinCEN last month, which identified a Russia-based virtual currency exchange “as a ‘primary money laundering concern’ in connection with Russian illicit finance” (covered by InfoBytes here), OFAC reiterated that the U.S. and UK are “committed to using all available authorities and tools to defend against cyber threats.” The designations follow other joint sanctions actions taken by the two countries and reflect findings that sanctions are most effective in coordination with international partners, OFAC said.
