Dallas -- Approximately 1.1 million debit and credit cards used at Neiman Marcus stores may have been compromised in a security breach last year, according to an update posted on the retailer’s website. To date, Visa, MasterCard and Discover have notified the company that approximately 2,400 unique customer payment cards used at Neiman Marcus and Last Call stores were subsequently used fraudulently.
In the post, the company reiterated that Social Security numbers and birth dates were not stolen and customers who shopped online were not affected. Customers that use the chain’s private Neiman Marcus credit cards were also not affected.
The company, which said that the investigation is ongoing, learned that malicious software was installed to its system on Jan. 1, after a forensics company discovered it. It informed federal law enforcement agencies and began working with the U.S. Secret Service and payment processors.
Neiman Marcus said, to its knowledge, there was no connection between the security breach at its company and the one at Target.
