Technology giant Microsoft and the US Justice Department said on Thursday they had seized more than 100 websites they allege were being used by Russian groups to commit computer fraud and abuse in the United States.

Between January 2023 and August 2024, Microsoft observed the group, code-named “Star Blizzard,” target more than 30 civil society entities and organisations, including journalists, think tanks, and non-governmental organisations, a joint statement said.

“The Russian government ran this scheme to steal Americans’ sensitive information, using seemingly legitimate email accounts to trick victims into revealing account credentials,” Deputy Attorney General Lisa Monaco said.

“With the continued support of our private sector partners, we will be relentless in exposing Russian actors and cybercriminals and depriving them of the tools of their illicit trade.”

Star Blizzard was “persistent,” Microsoft said.

“They meticulously study their targets and pose as trusted contacts to achieve their goals,” the company said.

“While we expect Star Blizzard to always be establishing new infrastructure, today’s action impacts their operations at a critical point in time when foreign interference in U.S. democratic processes is of utmost concern.”

Microsoft has previously warned that Russian operatives are attempting to influence the U.S. presidential election in November. (dpa/NAN)
