A security analysis reveals that credit card numbers are vulnerable to brute force attacks due to predictable patterns and weak validation mechanisms. The article discusses how attackers can systematically guess valid card numbers, expiration dates, and CVVs with relative ease. This highlights significant flaws in current payment card security practices.
Background
Credit card security relies on combinations of numbers (card number, expiration, CVV) that can be systematically guessed if validation systems are not properly rate-limited. Many online payment systems lack robust anti-brute force protections, making this a persistent threat.
