BOSTON—One of five Russian nationals who authorities allege made tens of millions of dollars in illegal profits by trading shares of companies using information stolen during hacks of U.S. computer networks has been extradited to the U.S. to answer to the charges, federal prosecutors in Boston announced Monday.
Vladislav Klyushin, 41, whose last name is sometimes spelled Kliushin, was arrested in Sion, Switzerland, on March 21 and was extradited to the U.S. on Dec. 18, acting U.S. Attorney for Massachusetts Nathaniel Mendell said.
