How to Protect Your CVV from Brute Force Attacks

Understanding the threat of a CVV attack is crucial for online shoppers. CVV, or Card Verification Value, is a three or four-digit number printed on credit cards that is used to prevent unauthorized transactions. Brute force attacks, where an attacker tries every possible combination to gain access, pose a significant risk to this information.
