A Russian national found guilty of hacking into corporate earnings databases to steal and trade on nonpublic information about companies like Tesla and Roku was sentenced Thursday to nine years in prison.

The sentence for Vladislav Klyushin, handed down by a federal judge in Boston, adds to the U.S. government’s roster of Russian nationals in its possession as U.S. officials seek potential bargaining chips in a negotiated prisoner swap with Moscow for Americans, including the detained Wall Street Journal reporter Evan Gershkovich.

The U.S. government had sought 14 years in prison for Klyushin, who was convicted by a federal jury in Boston in February of what the Justice Department described as a scheme that netted $90 million through securities trades based on nonpublic information stolen from U.S. computer networks. He was also ordered to be deported at the end of his sentence, and to forfeit $34 million, with restitution to be determined at a later date, the U.S. Attorney’s Office for the District of Massachusetts said.
