Quick-and-Dirty (And Dangerous) Wi-Fi Retail Deployments Likely To Be Rampant In 2012

Written by Evan Schuman

As mobile trials of all kinds kick into highgear next year, there’s almost certainly going to be a trend that will signal very bad security news: a soaring number of retail Wi-Fi trials, many of which will likely be quick-and-dirty efforts to be able to support customers who want to use mobile in-store. Wi-Fi security is bad enough as is, let alone what will happen with lot of slapdash rollouts.

Some of the security problems with Wi-Fi are well known and there isn’t a security consultant worth the paranoia they sell who can’t spout their list of the dumbest retail Wi-Fi deployments. There is a small ray of hope. Although Wi-Fi is often quite insecure, the newest Wi-Fi offerings today are a tad bit better. If we can assume that many of the new deployments will be using somewhat more robust approaches, it might be a somewhat smaller catastrophe. Remember that a Wi-Fi mobile disaster doesn’t have to be a security breach. Given how easy it is for a children’s toy or a wireless microphone to disrupt Wi-Fi and potentially halt mobile payments or, even worse, cause double billings, even a data-secure network could cause mobile nightmares. Ahhh, the joys of Wi-Fi.

  1. Steve Gurney Says:

    Since chip & pin (EMV) was introduced, the majority of stores, restaurants, hotels, small businesses in Europe have wireless based payment terminals.

    Over the past several years I’ve not seen large scale wi-fi security breaches, or wi-fi disruptions that you talk about. Given that they are obviously using ‘old’ wi-fi technology, and as stated by you, how easy it is to disrupt wi-fi signals we should be well aware of wi-fi’s failings given its widespread adoption for payments in EMEA & APAC?

    So the existing extensive use of wi-fi In payments and lack of issues doesn’t tally with your predictions.

  2. Richard Nedwich Says:

    While a blanket statement of alarm may be too cautionary, there is some merit for concern.

    Major retailers generally follow PCI guidelines, and have IT staff to enforce security policies by choosing reputable enterprise-class WLAN vendors, and following their training and best practices. In fact, some have argued that wireless security is actually superior to wired security in many ways.

    However, the quick serve market of cafes and restaurants and gas stations, etc. have no such IT staff or large budgets to choose enterprise class solutions. While some find it best to rely upon a reputable managed service provider, perhaps too many simply ‘go their own’ by running down to the local Best Buy, or ask some kid on staff to ‘plug and pray’ in order to satiate customer desire for constant connectivity while they sip their java, eat their burger or fill up the tank.

    This is where what you don’t know can hurt you.

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...
