Cloning credit cards today – 9 October 2014, its not hard to do as expert shows.

The new age of credit card skimming and cloning credit cards is on show today at the Breakpoint security conference in Melbourne.

peterfillmore-212x300Peter Fillmore an Australian money hacker & security boffin will demonstrate how he probed the protocols behind Visa and Mastercard payment cards and proved the viability of an attack by successfully using cloned versions of his credit cards to shop at supermarket chain Woolworths, and buy beer at a Sydney pub.

He will show today via modded Nexus 4 phone and how it steals data from Paywave and Paypass cards that could be introduced into cloned cards.

While the phone tactic is an inconspicuous attack, Fillmore told Vulture South that enterprising criminal gangs could make a killing by using his tactics with more powerful custom equipment to scam commuters on their way to work.

“The phone needs to be really close to someone’s wallet to work so it’s more of a proof-of-concept. [However], the attack I would be worried about is a criminal gang with a [reader] in a briefcase who captures a whole lot of cards on a tram and uploads them to a central server,” Fillmore said.

“Someone located far away could then wait until their phone pings with the stolen information and start using the cards,” he added.

“This is better than a relay attack because you can store the transactions and you don’t have a timeframe,” he said.
There’s another advantage for the potential criminal, as when the trick fails, it appears to the retailers and banks to be a mundane error, rather than a fraud attempt, which could trigger a well-resourced bank and police investigation.

Large retailers are first choice targets for attack (rather than small new businesses) as they were likely, as in the case of Woolworths, to operate legacy point-of-sale payment equipment and therefore be more open to fraudulent moves.

The Nexus 4 (as Fillmore discovered) served as an efficient and discrete hardware fuzzer for contactless cards. The popular Cyanogen mod gave access to an otherwise inaccessible application programming interface called ‘Host Card Emulation’ that he said is a “great platform” for cloning cards.

Fillmore plans to write an exploit app for a popular but as yet unnamed card reader that would be delivered through the phone.

His attack worked in part by exploiting payment terminal’s legacy support for magnetic stripe cards. The EMV (the gold chip on credit cards) protocol meant cards told terminals if it supported EMV, which then allowed an attacker to pushed payment processing back to mag stripes.

The attacks weren’t due to particular problems with a given bank, although the Australia and New Zealand Banking Group (unlike the National Australia Bank) was found to have not implemented a randomisation number which while affording additional security, did not prevent the attack.

Fillmore said new startups may be harder targets as they may use new technology that could be, like one tested at a NAB ATM, capable of determining if a contactless credit card was ‘lying’ about not supporting EMV.

Blocking the attack would require the very slow process of dropping legacy support for non-EMV transactions, a feat that could be done faster in Australia than the US.

“I believe that EMV interfaces in general (both RFID and physical) is an area ripe for implementation bugs and errors,” Fillmore said. “Its just the lack of available/affordable test equipment which has prevented researchers from exploiting this area.”

He said the attack may work similar to Cupertino’s Apple Pay platform which supported non-EMV transactions.
