Dokuchaev and Sushchin allegedly hired the hacker Alexey Belan, as well as Karim Baratov who was arrested in Canada, to obtain information from at least 500 million Yahoo accounts. The pair directed the conspiracy from about April 2014 up to at least December 2016.

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."

All young men in their twenties, Klepikov, Bron, and Penchukov were a group in Evgeniy Bogachev's (Slavik's) inner ring of organised cyber-crime.

A variant of Bogachev's infamous "Zeus" malware, "Jabber Zeus" came with the instant-messaging plug-in Jabber, which allowed the group to coordinate their attacks.

According to a Wired report, Penchukov ("tank") led the group, Klepikov ("petr0vich") ran IT management, and Bron ("thehead") moved the gang's money internationally.

The FBI raided Penchukov and Klepikov's homes in 2010, seizing 20 terabytes of data.
