Verifone: Steal This Card Data

Written by Frank Hayes and Evan Schuman
March 9th, 2011

In an ironic move, payment security vendor VeriFone on Wednesday (March 9) posted a video showing how to turn a mobile payment device into an illegal skimming unit. Not only did it post a video depicting this technique, VeriFone also posted a skimming application it wrote and encouraged consumers to download it.

VeriFone did this all to attack a much smaller rival called Square, which it repeatedly identified by name. The ironies continue. VeriFone posted a special page for this content, including a domain name referencing its rival, Square: http://www.sq-skim.com/. A key part of that page was a YouTube icon that would play the video. But YouTube quickly took down the video, breaking the link.

The video itself encouraged people to grab a copy of VeriFone’s application, which is designed to turn Square’s dongle into an unencrypted skimming device. VeriFone CEO Douglas Bergeron narrates the video and says the site is “where you can download the sample skimming application and see for yourself.” And yet, no such link exists on the page. The link was removed, just as the YouTube video was.

Late on Wednesday, VeriFone spokesman Peter Bartolik confirmed that the file had been removed. “The app has been taken down and won’t be restored.” Oddly, the reference on the page that the app can still be downloaded remains, albeit with no link, as of 9:30 AM Thursday (March 10).

Bartolik offered an explanation for the app’s removal: “It became evident that some observers were coming to the conclusion that VeriFone had made available an actual skimming app, which was not the case. The app we made publicly available was a demonstration app that showed an ability to read data from a Square device, but did not actually display or capture sensitive card data. However, in order to curtail further confusion, we have removed the demo app. The video is self explanatory.”

The only concern here is the point that “some observers were coming to the conclusion that VeriFone had made available an actual skimming app.” From their statement, it’s easy to see where that impression came from.

The statement, on VeriFone’s Web page, attributed to Bergeron, said: “In less than an hour, any reasonably skilled programmer can write an application that will ‘skim’—or steal—a consumer’s financial and personal information right off the card utilizing an easily obtained Square card reader. How do we know? We did it. Tested on sample Square card readers with our own personal credit cards, we wrote an application in less than an hour that did exactly this.”

That’s pretty clearly stating that the application being referenced was skimming numbers. Bergeron’s statement later says, “See for yourself by downloading the sample skimming application.” Also, how could an application show “an ability to read data from a Square device” without actually doing it? The video showed the app doing its work—which is a demonstration of the app—but by also offering to download the actual “sample skimming application,” it’s hard to envision any other reasonable interpretation.

Why Did Gonzales Hackers Like European Cards So Much Better?

I am still unclear about the core point here-- why higher value of European cards. Supply and demand, yes, makes sense. But the fact that the cards were chip and pin (EMV) should make them less valuable because that demonstrably reduces the ability to use them fraudulently. Did the author mean that the chip and pin cards could be used in a country where EMV is not implemented--the US--and this mis-match make it easier to us them since the issuing banks may not have as robust anti-fraud controls as non-EMV banks because they assumed EMV would do the fraud prevention for them Read more...
Two possible reasons that I can think of and have seen in the past - 1) Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code. 2) Also, in offline chip countries the card determines whether or not a transaction is approved, not the issuer. In my experience, European issuers haven't developed the same checks on authorization requests as US issuers. So, these cards might be more valuable because they are more likely to get approved.

A smart card slot in terminals doesn't mean there is a reader or that the reader is activated. Then, activated reader or not, the U.S. processors don't have apps certified or ready to load into those terminals to accept and process smart card transactions just yet. Don't get your card(t) before the terminal (horse). Read more...
The marketplace does speak. More fraud capacity translates to higher value for the stolen data. Because nearly 100% of all US transactions are authorized online in real time, we have less fraud regardless of whether the card is Magstripe only or chip and PIn. Hence, $10 prices for US cards vs $25 for the European counterparts. Read more...
@David True. The European cards have both an EMV chip AND a mag stripe. Europeans may generally use the chip for their transactions, but the insecure stripe remains vulnerable to skimming, whether it be from a false front on an ATM or a dishonest waiter with a handheld skimmer. If their stripe is skimmed, the track data can still be cloned and used fraudulently in the United States. If European banks only detect fraud from 9-5 GMT, that might explain why American criminals prefer them over American bank issued cards, who have fraud detection in place 24x7. Read more...
