And about the wonders of those debit cards....
DECEMBER 14, 2005 (COMPUTERWORLD) - A victim of the recent Sam's Club
security breach suggests that fraudsters may have stolen credit card
information by using illegal "card-skimming" devices attached to the
pumps at the company's gas stations. The fraudulent activity may also
have been going on for a longer period than that suggested by the
wholesale giant, and it may affect thousands of people (see "Update:
Security breach at Sam's Club exposes credit card data").
Sam's Club, a division of Bentonville, Ark.-based Wal-Mart Stores
Inc. , said in a brief Dec. 2 statement that it was investigating a
security breach that had exposed the credit card data of an
unspecified number of customers who bought fuel at its gas stations
between Sept. 21 and Oct. 2. The company said it was alerted to the
problem by credit card issuers whose customers were complaining of
fraudulent charges on their statements.
Apart from saying that "electronic systems and databases used inside
its stores" were not involved, Sam's Club officials have refused to
disclose what happened. They have not returned repeated telephone
calls for comment.
The breach prompted the Alabama Credit Union (ACU) to block and
reissue debit cards to about 500 of its customers after it learned of
the problem last week. The ACU was alerted to the breach by Credit
Union National Association Inc. , according to Kayce Bell, chief
operating officer at the Tuscaloosa, Ala.-based credit union.

Looks like thousands and thousands of folks. And their pins too. I
hope that the contract with the issuer was nice and solid.
I don't know anything more about this case than what you've written
here, but this reads very much as "my dog ate my homework". Perhaps
I'm overly sceptical, but this sounds like Sam's Club had poor
security on their financial systems, and kept a list or database of
essential credit card data in one place (many companies do, placing
the convenience far above security or customers' privacy). This list
got stolen (either an inside job or an outside job). This has
happened to companies before - it's a public relations disaster.
Blaming advanced fraudsters with "card-skimming" devices turns it
around - suddenly Sam's Club is the victim, and customers and their
issuing banks are to blame for using cards open to such fraud.
I'm not saying card-skimming doesn't happen, or doing anything more
than speculating in this case. I just don't think it is a clear
example without a great deal more evidence.
I guess it depends if the claimed devices are hypothetical or if Sam's
has evidence they actually existed, eg one of the devices. It seems to
me that they would be foolish to float this story if they had no actual
evicence. People say a lot of things about Walmart Corp, but foolish
doesn't seem to be one of them.
If people had found out that their cards were compromised, the story was
going to float anyway. This way Sam's can look like the victim of a
crime, and play the responsible customer-oriented company by telling
people. With luck, the investigations could be made to take so long
that the case fades away and the real truth is never brought to the
public attention. That would certainly not be a foolish strategy.
However, it is pure conspiracy-theory speculation for which I have no
evidence whatsoever - especially as such skimming devices do exist.
