What is a Card Enumeration Attack?

A card enumeration attack is a type of cyber attack that targets payment card data. The attacker's goal is to steal sensitive information from payment card accounts by determining valid card numbers and corresponding account details.

How Does a Card Enumeration Attack Work?

These attacks typically involve the use of automated scripts to try different combinations of numbers on a payment card form. If the correct card number is entered, the attacker can access the cardholder's information, including the expiration date, CVV (Card Verification Value), and other personal data.
