PIN-stealing vulnerability found in popular PoS terminal

Researchers swipe card data, install Pong on payment terminals.

Germany’s most popular Point of Sale (PoS) terminal contains a buffer-overflow vulnerability which allows payments cards to be cloned and PINs captured.

Thomas Roth, a 21 year-old hacker in that country successfully swiped card credentials and spoofed a fake transaction without requiring physical access to the Hypercom Artema Hybrid PoS.

The faked transaction would bluff cash registers into accepting the transactions as legitimate and serve to hide the fraud from customers.

The attacks targeted the terminal’s application processor and could hijack the display and PIN pad. The cryptographic Hardware Security Module which stores payment data was unaffected, Roth’s security firm srlabs said.

Researchers said the vulnerability was dangerous because many devices could be attacked if hackers gained access to a retail network.

Roth demonstrated the vulnerabilities further for Germany's ARD TV by installing an instance of the game Pong on one of the PoS devices. 

While the manufacturer promised to release a patch for the flaw, another flaw was discovered in that the JTAG debugging interface could be accessed without opening the device.

Srlabs said the interface could not be switched off.

“Deployed devices will likely stay vulnerable to local attacks, potentially undermining trust in cash-less payment considerably for a long time,” researchers said.

The country's banking industry group said EMV cards could not be duplicated, but researchers said it would not stop attackers.

“Unfortunately, the world-wide payment infrastructure’s planned updates to EMV do not protect from compromised terminals.”
