Barnes & Noble has been attacked by hackers and the PIN pads in 63 of its stores have been compromised. In response, the book retailer has discontinued the use of PIN pads in all of its stores nationwide. The company is recommending that customers who shopped in the affected stores in September should change the PINs on their ATM cards and check their credit card  statements for any suspicious charges.

The New York Times broke the news last night. Check it out: “The company discovered around Sept. 14 that the information had been stolen but kept the matter quiet at the Justice Department’s request so the F.B.I. could determine who was behind the attacks, according to these people.”

Barnes & Noble said in a press release that its customer database is secure and that Barnes & Noble.com, Nook and Nook mobile apps were unaffected.
