Hacker Predicts AMEX Card Numbers, Bypasses Chip and PIN
30th November 2015
Brainiac hacker Samy Kamkar has developed a US$10 gadget that can predict and store hundreds of American Express credit cards and use them for wireless transactions, even at non-wireless payment terminals.
The mind-blowing feat is the result of Kamkar cracking how the card issuer picks replacement numbers, and in dissecting the functionality of magnetic stripe data.
It means criminals could use the tiny gadget to keep pillaging cash after cards have been cancelled at businesses that do not require the three or four -digit CVV numbers on the back of cards.
American Express has been notified and says it is working on a fix.
I should hope so. I am very glad I do not use an Amex card.
