Card Testing Attack Guide

What is a Card Testing Attack?

A card testing attack is a type of cybercrime where attackers attempt to determine the validity of credit card numbers by making small purchases or test transactions. This method is often used to check if a card is active and has available credit.

How Does a Card Testing Attack Work?

The attacker typically starts by generating a batch of randomly generated credit card numbers. They then use these numbers to make small purchases, often at online stores that offer quick returns or chargebacks. If the transaction is successful, it indicates that the card is active and may have enough credit to be worthwhile for further attacks.

Risks of a Card Testing Attack

Victims of a card testing attack may experience unauthorized charges, financial loss, and damage to their credit score. It's important to monitor your accounts regularly and report any suspicious activity immediately.
