Koncrete, an online podcast, always publishes amazing interviews with notorious fraudsters and this month they published another blockbuster.

In this episode, they interview John Boseak, one of the most prolific credit card fraudsters of the early 2000s. He was discovered by another mortgage fraudster turned author- Matt Cox – in prison and Matt later went on to write a book about Boseak’s escapades called Bent.

The book describes Boseak as not your typical computer geek. He was, however, one of the most cunning scammers, counterfeiters, identity thieves, and escape artists alive—and a major thorn in the side of the U.S. Secret Service as they fought a war on cybercrime.

With a savant-like ability to circumvent banking security and stay one step ahead of law enforcement, Boseak made millions of dollars in the international cyber underworld, with the help of the Chinese and the Russians.

The interview takes shows his journey from counterfeiting fraudster to online commerce fraudster. At his peak, he was producing 600 to 800 perfect counterfeit cards a day and was making up to $20,000 for his work.
