Carding means unauthorized use of credit/debit card numbers to purchase goods, services or gift cards. The term has changed during the last years, and now it includes various activities surrounding the use of card information. These can be re-shipping procedures, phishing, computer hacking, cashing out and so on.
Carders, such as Buyccfullz, Fullzshop and Buycvv2, own large numbers of card numbers. They use various methods to retrieve data from thousands of cards. Carding involves hundreds and even millions of accounts. Besides, it's easy for carders to stay anonymous.
