On March 9, the Justice Department extradited and arraigned Ukrainian national Yaroslav Vasinskyi for his alleged involvement in a variety of cyber crimes including the Kaseya hack.
Vasinskyi and a another alleged REvil group member, Yevgeniy Polyanin, were initially arrested back on Nov. 8, 2021 as part of a joint law enforcement operation between the United States, Europol and the Romanian police. Vasinskyi was then extradited to and arraigned in the Northern District of Texas on March 9.
Vasinskyi is alleged to be responsible for the ransomware attack against Kaseya on July 2, where he "caused the deployment of malicious Sodinokibi/REvil code throughout a Kaseya product that caused the Kaseya production functionality to deploy REvil ransomware to “endpoints” on Kaseya customer networks." The two individuals are being charged separately with Vasinskyi's charges including "conspiracy to commit fraud and related activity in connection with computers, damage to protected computers, and conspiracy to commit money laundering.” And if convicted, the charges carry a total penalty of 115 years.
