If you know the right people — and if you can get other criminals to vouch for you — you can go online and buy huge bundles of stolen credit cards.
As it turns out, Planet Money knows the right people.
On today's show, we sit in with Keith Mularski of the FBI. Mularski got so deep into this world that he wound up running a major criminal website.
He takes us to a giant online mall for stolen credit cards, where vendors offer discounts for repeat customers and banners advertise hacking and phishing tutorials.
