Reports: Neiman Marcus hit by credit card…

The database of credit card customers at Neiman Marcus was hacked in December, according to a published report late Friday on CNET.com

Security news CNET's confirmation of the Neiman Marcus hack follows Target's revelation Friday that its probe into a recent attack there affected personal and credit card data of up to 110 million of the upscale retailer's customers. That's 70 million more than what Target first said had been affected.

A blogger at NPR also reported the Neiman Marcus hacking late Friday.

The Neiman Marcus breach occurred around mid-December, the same time as the Target attack, according to the CNET story.

So far, as happened with the Target breach, Neiman Marcus' online customers do not appear to be affected so far. The hack was aimed at shoppers at the bricks-and-mortar locations of the luxury retailer.

But it's far too early to tell whether the attacks might be related or somehow coordinated, the CNET story said.

In its story, CNET quoted Ginger Reeder, a spokesperson for Dallas-based Neiman Marcus. She told the Brian Krebs, an independent security researcher who discovered the breaches, that details regarding the Neiman Marcus attack are sketchy.

"The cause, size, and duration of the attack are currently unknown, pending the completion of a third-party forensics investigation. The company is also working with the Secret Service, as is customary in these attacks," the CNET story said.
