For years no one knew who the man behind the screen-name "Slavik," was. Dubbed "Russia's most notorious hacker" by Wired, Bogachev invented malware named "Zeus," which the FBI started investigating in 2009. "Zeus" was used to capture bank account numbers and passwords.
A modified version of "Zeus" called "GameOver Zeus" infected over a million computers and was used to steal over $100 million. Bogachev also used "GameOver Zeus" to infiltrate Ukrainian computers for politically sensitive information at the time of the Russian annexation of Crimea.
In 2012, Bogachev was indicted under the screen-name "lucky12345," and finally he was indicted under his true name in 2014. There is a bounty of up to $3 million for information relating to Bogachev. The FBI also notes that he is, "known to enjoy boating."
