An ATM hack and a PIN-pad hack show chip cards aren’t impervious to fraud

The good news? Hacks are limited for now. The bad news? Hackers will get better. Security researchers are eager to poke holes in the chip-embedded credit and debit cards that have arrived in Americans’ mailboxes over the last year and a half. Although the cards have been in use for a decade around the world, more brains trying to break things are bound to come up with new and inventive hacks. And at last week’s Black Hat security conference in Las Vegas, two presentations demonstrated potential threats to the security of chip cards. The first involved fooling point-of-sale (POS) systems into thinking that a chip card is a magnetic stripe card with no chip, and the second involved stealing the temporary, dynamic number generated by a chip card and using it in a very brief window of time to request money from a hacked ATM.

Double trouble
