According to Intel 471, a cyber intelligence firm Stroganov is with some of the major cyber threats since 2001. Stroganov and his associate Gerasim Silivanon (a.k.a. “Gaborik “) were also sentenced to six years of imprisonment in Russia in 2006 but were out in two years. “Our continuous monitoring of underground activity revealed despite the conviction, Flint24 never left the cybercrime scene,” reads an analysis by Intel 471. “You can draw your conclusions [about why he was released early],” Sporaw wrote, hinting at the use of unfair means to get out of jail early. Flint is one of the big players of the stolen credit card market, working as a wholesaler of credit card data with cyber crooks who bought these cards from him in bulk – 100,000 pieces at once.
Various cyber forums say that Stroganov and his guys were caught because they broke “the golden rule” of hackers from Soviet countries- never target your country people or bank. Flint’s “Trust Your Client” These carding sites had a standard scheme they supported to earn trust and loyalty from those who bought these stolen cards. This system allowed their customers to get instant refunds on bad cards without proving that the tickets were canceled by the bank before they could be used. So, these sites installed money-back insurance called “checkers,” which can be used by their customers to check the cards (accessible only for a few minutes of buying the tickets) by giving extra money, few cents per card. But slowly, it was claimed that these checkers gave inaccurate results to benefit the card shops.
So, Flint and his gang came up with a policy “Trust your client,” through which if the customer claimed that the card was fraudulent, they would get a refund no question asked but only within six hours of buying the ticket. But they probably had their checkers too for checking bad cards.
