Chip-enabled smart credit cards can be easily hacked
At the Black Hat cybersecurity conference in Las Vegas, two security researchers showed how it is actually very easy to take control of a shop owner's credit card terminals, even if the shop uses the latest chip-and-PIN smart machines.
The hack is very simple: just insert a smart card with malware into the machine, and the terminals would be fooled to think that the cards passed through them are authentic bank cards. All day long, the machine gathers the information. At day's end, the hacker returns with the malware card, which sucks all that data out of the machine. The store clerk wouldn't even notice.
