Buying an ATM Skimmer
ATM skimmers—or fraud devices that criminals attach to cash machines in a bid to steal and ultimately clone customer bank card data—are marketed on a surprisingly large number of open forums and Web sites. For example, ATMbrakers operates a forum that claims to sell or even rent ATM skimmers. Tradekey.com, a place where you can find truly anything for sale, also markets these devices on the cheap.
The truth is that most of these skimmers openly advertised are little more than scams designed to separate clueless crooks from their ill-gotten gains. Start poking around on some of the more exclusive online fraud forums for sellers who have built up a reputation in this business and chances are eventually you will hit upon the real deal.
Generally, these custom-made devices are not cheap, and you won’t find images of them plastered all over the Web.
