A man who authorities say participated in a ransomware campaign that extracted tens of millions of dollars from victims has been charged in the United States, the Justice Department announced Thursday. Mikhail Vasiliev, a dual national of Russia and Canada, was arrested Wednesday. He is currently in custody in Canada and is awaiting extradition to the U.S. on charges that accuse him of involvement in the Lockbit ransomware operation. No lawyer for the 33-year-old Vasiliev, of Bradford, Ontario, Canada was listed on the court docket. He faces charges of conspiracy to intentionally damage protected computers and to transmit ransom demands.
