Card Enumeration Attack Guide

What is a Card Enumeration Attack?

A card enumeration attack is a type of cyber attack where an attacker tries to identify the card number, expiration date, and CVV of a credit or debit card. This information can be used to make unauthorized purchases online.

How Does It Work?

Attackers often use automated scripts to test a large number of card numbers against a compromised payment system. If the system responds with a successful transaction, the card details are captured.

Preventing Card Enumeration Attacks

• Use strong, unique passwords for all online accounts.
• Enable two-factor authentication where available.
• Be cautious of phishing scams and suspicious emails.

Protecting Your Transactions

When shopping online, always look for signs of a secure website, such as a lock icon in the browser's address bar. Additionally, consider using a virtual credit card or a payment service that offers extra security measures.
