Gonzalez Case Raises Very OId Retail Security Issues

August 23rd, 2009

“We had this case all worked out. I saw my client on Tuesday and we had this thing zipped, locked, sealed and ready to go forward,” Palomino said. “They were not supposed to indict him on Wednesday. We’re trying to bring closure. Everyone is trying to wash their hands (by dumping all charges on Gonzalez). I’m not saying that he didn’t do anything.”

Of course, the real issue here is: How can a group of people like this had been able to successfully penetrate such a lengthy Who’s Who of major retailers? The indictments have alluded to—but not identified—either two or three other major chains that were breached.

The Boston indictment vaguely refers to one major retail chain, but doesn’t identify the chain. We’ve spoken with someone from that chain who asked that their name—for now—remain secret. The New Jersey indictment explicitly refers to two retail chains that it is keeping secret, for the moment. Federal authorities—both at the Justice Department and the New Jersey U.S. Attorney’s Office—wouldn’t say if the unidentified retail chain referred to in the Boston indictment is one of the two referenced in the Newark indictments. That’s why we’re saying there are either two or three unidentified retail chains involved.

Were the thieves’ tactics so sophisticated or were the retail chains’ security so lax? (Yeah, we don’t quite need a show of hands to answer that last question. As Yoda would have said, “Einsteins, these attackers were not.”)

The crucial next question is “These break-ins happened months—and, in some cases, years—ago. Are these—and other—retail chains still as vulnerable today? Security is always great at fighting the last war. In other words, it’s unlikely that the old assaults from this crew would be nearly as successful today with larger chains. But that’s the point. These crews won’t mount the same kinds of attacks again. They’ll sniff around, find another huge vulnerability and attack again in a different way. (In a terrorism context, the next 9/11 won’t likely involve hijacked commercial aircraft.)

But we won’t need to ponder this hypothetical for very long. As long as zero liability and an absence of meaningful data protection laws exist, retailers can’t justify investing in the security they truly need. So the next group of Gonzalezes will be around shortly. Truth be told, they’re probably already in your system right now. We simply won’t realize it for six more months.

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...
