Neiman Marcus Group Ltd., the luxury retailer, said about 1.1 million credit cards may have been compromised in a data breach that occurred last year.
Visa, MasterCard and Discover have notified the Dallas-based department store chain that about 2,400 cards used at its stores between July 16 and Oct. 30 were used fraudulently, according to a statement today. Online shoppers weren’t affected, the company said.
Closely held Neiman Marcus is the second U.S. retailer to announce a customer data-security breach. Minneapolis-based Target Corp. (TGT:US) has said as many as 110 million customer accounts were compromised during the holiday shopping season by the theft of information including names, home and e-mail addresses as well as credit and debit card data.
On Dec. 17, the chain received a report that about 122 MasterCards had been used in one of its stores, the company said in a Jan. 22 letter to Senator Richard Blumenthal, a Democrat from Connecticut.
