Barnes & Noble Probes PIN Keypad Hack

Criminals hacked one PIN keypad in each of 63 stores and have already used the stolen data to commit fraud. Was it an inside job?

Barnes & Noble Wednesday confirmed that point-of-sale systems in 63 of its stores had been physically hacked as part of what it described as "a sophisticated criminal effort to steal credit and debit card information from our customers who have swiped their cards through PIN pads when they made purchases at certain retail stores."

That information was disclosed to customers Wednesday via a data breach notification, as well as a related press release, both of which were distributed via the website of the California Attorney General.

According to Barnes & Noble, the hacked PIN pads--only one of which was hacked in each of the stores--were capable of "capable of capturing information such as name, card account number, and PIN," but only for in-person purchases in which a card was swiped. The company said that its online customer database hadn't been breached. Still, stolen information from the hacked PIN pads has reportedly already been used by fraudsters.

Barnes & Noble said that it detected the PIN pad tampering "during maintenance and inspection of the devices," and said it immediately discontinued the use of all PIN pads across its nearly 700 U.S. stores, disconnected and sent them to an offsite location for inspection, and informed federal authorities, who are now investigating the tampering. Barnes & Noble has now completed physical inspections of every PIN pad for tampering, but hasn't returned them to stores, owing to ongoing concerns over tampering and data theft.

"The PIN pads were removed from stores on September 14, and the transactions are being made now through the register," said Barnes & Noble spokeswoman Mary Ellen Keating via phone. She declined to comment on whether the bookseller might resume using PIN pads at a future date.

A senior Barnes & Noble official told The New York Times, which first reported the story of the data breach Wednesday, that the company did inform credit card companies about the data breach. But the Barnes & Noble didn't immediately disclose the breach to its customers. The company official said that the U.S. Attorney's Office for the Southern District of New York said the bookseller didn't need to alert customers to the PIN pad fraud until Dec. 24, 2012, so as to not interfere with related investigations.

The list of affected stores includes locations in nine states: California, Connecticut, Florida, Illinois, New Jersey, New York, Massachusetts, Pennsylvania, and Rhode Island.

In its Wednesday data breach notification to customers, Barnes & Noble said that "as a precaution, customers and employees who have swiped their cards at any of the Barnes & Noble stores with affected PIN pads" should immediately contact their bank to change the PIN number for their debit card, if one was used. The bookseller also recommended that both credit and debit card users review their account statements for unauthorized charges, and notify their banks if any were found. But it didn't detail--or perhaps simply doesn't yet know--when its PIN terminals were first hacked.

re: Barnes & Noble Probes PIN Keypad Hack
If this was an inside job the Barnes and Nobel has way overqualified sales people working the registers. GǣA sophisticated criminal effort does not sound like it could be committed by the sales clerk who just directed me to the travel section. Not at all putting down sales clerks but if you have the ability to carry out a sophisticated criminal attack then they are probably in the wrong field. 63 stores that were effected is quite a feat considering the security on these pos terminals, which leaves the obvious, an inside job.
