Sears Shuts Down Part Of Site, Concedes It Was Revealing Purchases

Written by Evan Schuman
January 5th, 2008

On the heels of admitting this week that it was using spyware on one of its E-Commerce sites, Sears on Friday said that it was temporarily shutting down part of another Sears E-Commerce site after admitting that it allowed consumers to see explicit details about the purchases of other consumers.

The Sears move came hours after Harvard Business School Assistant Professor Benjamin Edelman published details on how consumers using Sears’ ManageMyHome site could find detailed purchase histories about other Sears shoppers merely by typing in their name, phone number and street address into the site. (Related story: analyzing a lawsuit filed against Sears for its latest data breach.)

"Sears offers no security whatsoever to prevent a ManageMyHome user from retrieving another person’s purchase history," Edelman wrote on his blog. "To verify a user’s identity, Sears could require information known only to the customer who actually made the prior purchase. For example, Sears could require a code printed on the customer’s receipt, a loyalty card number, the date of purchase, or a portion of the user’s credit card number. But Sears does nothing of the kind. Instead, Sears only requests name, phone number, and address, which is all information available in any White Pages phone book."

Edelman posted several examples, referencing incidents from Washington, D.C., the town of Brookline, Massachusetts and Lincoln, Mass..

Sears was E-mailing a statement late Friday that because of these privacy concerns, "we have turned off the ability to view a customer’s purchase history on Manage My Home until we can implement a validation process that will restrict access by unauthorized third parties."

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...
