The first website Burkov operated was an online marketplace for buying and selling stolen credit card and debit card numbers—called Cardplanet—which roughly hosted 150,000 payment card details between the years 2009 and 2013.
Cardplanet marketplace offered stolen payment card details for anywhere between $2.50 and $10 a card, depending on the card type, country of origin, and the availability of card owner information.
"Many of the cards offered for sale belonged to U.S. citizens. The stolen credit card data from more than 150,000 compromised payment cards was allegedly sold on Burkov's site and has resulted in over $20 million in fraudulent purchases made on U.S. credit cards," the Department of Justice said in an old press release.
The majority of such stolen credit cards are obtained using illegal means such as phishing and the use of banking malware, malicious software implanted into cash registers at the stores, leaked databases, and hacked financial account passwords.
Besides Cardplanet, Burkov also masterminded a separate invite-only forum website for elite cybercriminals where they advertised stolen personal identity information, malicious software, and other illegal services, like money laundering and hacking services.
According to local media, Russia last year offered Israel to release one of its citizens Naama Issachar, who was sentenced in Russia for drug offenses, in exchange for Burkov's release, but Israel turned down that offer and allowed his extradition to the United States.
On admitted charges of access device fraud and conspiracy to commit computer intrusion, identity theft, wire, and access device fraud and money laundering, Burkov is facing a prison sentence of up to 15 years, which will be announced by the federal court in Alexandria on 8th May 2020.
