Carding is a type of online fraud where criminals use stolen credit card information to make unauthorized purchases. This process often involves obtaining card details through hacking, phishing, or buying them on the dark web. The goal is to use these details to buy goods or services without the cardholder's consent. Once the fraudsters acquire the card information, they may test its validity by making small purchases. If successful, they proceed to larger transactions. Carding can lead to significant financial losses for both individuals and businesses, prompting the need for enhanced security measures in online transactions and payment systems.
