What is a Card Testing Attack?
A card testing attack is a method used by cybercriminals to verify the validity of stolen credit card information before using it for fraudulent transactions. These attacks can be damaging to individuals and businesses alike, as they compromise sensitive financial data.
Methods Used in Card Testing Attacks
Chip and Pin Verification: By using a cloned card with the stolen card's information, cybercriminals attempt to verify the card through the chip and PIN system.
Online Verification: Cybercriminals use online platforms to test the validity of stolen card numbers by making small purchases or checking the card's balance.
ATM Testing: Stolen card information is used at ATMs to test if the card is active and can be used for cash withdrawals.

Regularly Monitor Your Statements: Keep a close eye on your credit card statements for any unauthorized transactions.
Use Two-Factor Authentication: Where available, enable two-factor authentication for all your financial accounts.
Report Suspicious Activity: If you suspect any fraudulent activity, report it to your bank immediately.
Keep Your Card Information Secure: Never share your card details, CVV, or PIN with anyone.
