Card enumeration attacks are a serious threat to online security. In this guide, we'll explore what they are, how they work, and most importantly, how to protect yourself against them.

What is a Card Enumeration Attack?

A card enumeration attack is a type of cyber attack where an attacker uses a series of automated attempts to guess or identify the card details of a victim. This is typically done by attempting to guess the card number, expiration date, CVV code, and other sensitive information.

How Does It Work?

Attackers use automated tools to test a range of card numbers and other details against a website or payment gateway. If the card is valid, the attacker can use it to make fraudulent purchases or steal sensitive data.
