"Renukanth Subramaniam, from north London, established the website DarkMarket, which threatened every bank account and credit card holder in Britain and caused tens of millions of pounds of losses.
It was described as a "one-stop shop" for fraudsters buying and selling stolen details such as PIN numbers, account balances, answers to account security questions and passwords for social networking websites.
"The site even offered criminal users a secure payment system, training and advertising space to sell equipment used to clone bank and credit cards.
DarkMarket operated for almost three years as a “criminals only” forum, with more than 2,500 members at its peak, who could buy up to 10 credit card numbers along with other personal information for around £30.
It was shut down after a two-year global investigation in which undercover agents from the FBI and the Serious Organised Crime Agency infiltrated the site by posing as criminals.
A spokesman for Soca called it “one of the most pernicious online criminal websites in the world” and estimated that its victims lost tens of millions of pounds.
Officials said there was a code of “honour amongst thieves” on the site.
There was a secure payment system between criminals – described by Judge John Hillen as a "PayPal for criminals". "
