Neiman Marcus says fewer payment cards exposed in breach than first thought
Neiman Marcus has revised downward the number of credit and debit cards exposed in a data breach, from 1.1 million to 350,000, according to a notice posted Friday on its website.
“The number has decreased because the investigation has established that the malware was not operating at all our stores, nor was it operating every day in those affected stores,” wrote Neiman Marcus Group President and CEO Karen Katz.
In a new detail, Katz wrote that 77 of 85 stores were affected during the intrusion, which took place between July 16 and Oct. 30, 2013. However, Neiman Marcus also revised the number of card details that have been fraudulently used to 9,200, up from 2,400. Stolen card details are less useful to cybercriminals as time passes, as cards are cancelled by issuers if fraud is likely or the details expire.
