Even immediately, the RUSdot Mailer is marketed on the market on the high of the RUSdot group discussion board.
Stanx mentioned he was a longtime member of a number of main boards, together with the Russian hacker discussion board Antichat (since 2005), and the Russian crime discussion board Exploit (since April 2013). In an early submit to Antichat in January 2005, Stanx disclosed that he’s from Omsk, a big metropolis within the Siberian area of Russia.
In accordance with the cyber intelligence agency Intel 471, the person Stanx certainly registered on Exploit in 2013, utilizing the e-mail tackle stanx@rusdot.com, and the ICQ quantity 399611. A search in Google for that ICQ quantity turns up a cached model of a Vkontakte profile for a Denis “Neo” Kloster, from Omsk, Russia.
