Mark Vartanyan, known online as Kolypto, was sentenced by a U.S. District Court Judge Mark Cohen in Atlanta. He pleaded guilty in March to computer fraud, federal prosecutors said. Prosecutors said he helped develop, improve and maintain Citadel, which was designed to steal financial and personal identification information from computer networks. Citadel infected about 11 million computers worldwide and caused over $500 million in losses, prosecutors said in a statement. The sentence includes credit for the about two years he spent in Norwegian custody before he was extradited to the United States.”]
