Neiman Marcus

Credit card hackers might be developing a taste for the finer things in life.

Upscale department store Neiman Marcus confirmed that its database of customer information was hacked last month, independent security researcher Brian Krebs reported on Friday.

The Neiman Marcus hack follows news today from Target that its investigation into its recent hack found that thieves made off with the personal and credit card data of up to 110 million Target customers, 70 million more than previously thought.

The Neiman Marcus breach occurred around mid-December, the same time as the Target attack. Another similarity to the Target attack is that online Neiman Marcus shoppers do not appear to be affected so far, only retail shoppers. So far, these appear to be coincidences.

Ginger Reeder, a spokesperson for Dallas-based Neiman Marcus, told Krebs that details on the hack are sparse. 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.
