Case 034: Denis Gennadievich Kulkov

He didn’t steal the cards — he built the machine that made it possible.

In this episode of Fugitive Files, we unravel the story of Denis Gennadievich Kulkov, the alleged mastermind behind Try2Check, a dark web empire that helped cybercriminals verify stolen credit card numbers for nearly two decades.

Since 2005, Kulkov is accused of operating the notorious platform that enabled fraudsters to check the validity of millions of stolen credit cards — charging a fee per query and raking in an estimated $18 million in Bitcoin. While criminals cashed in, victims were left with drained accounts and shattered trust.

Now, U.S. authorities say they’ve traced his digital fingerprints across years of aliases and Bitcoin wallets — and they want him brought to justice. A $10 million reward has been issued for information leading to his capture.

Kulkov is currently at large and considered a major player in the cybercrime underworld. He faces federal charges of:

• Access device fraud

• Conspiracy to commit computer fraud

• Money laundering

• Operating an unlicensed money transmission business

This is Fugitive Files. Let’s get into it.
