Bogachev, thought to be at large in Russia, has been under indictment in the United States in connection with his alleged role as administrator of the GameOver Zeus botnet, believed to be responsible for the theft of more than $100 million from businesses and consumers in the U.S. and around the world. GameOver Zeus was an extremely sophisticated type of malware designed specifically to steal banking and other credentials from the computers it infected by either secretly logging keystrokes for passwords or creating false webpages where victims would unwittingly enter banking information and passwords.
