Carding
A carding is a process of obtaining, testing and using payment cards without a permission of the cardholder. Acquired information is sold on carding websites, including Websitetobuycvv, Cvvcarding, Buycvvwithhighbalance, Dumpswithpin2015 and many others
Bots
Carders don't engage in carding themselves; instead, they create bots to perform small purchases on hundreds of websites. Each time a bot tests a card number and create a list of active numbers. These numbers can be later used to buy products online. Carders can also use these cards themselves to obtain gift cards that can't be tracked
