Neiman Marcus: 1.1 million in-store customers affected by breach

Neiman Marcus Group said that about 1.1 million customers have been affected by a three-month security breach that the retailer initially disclosed in early January 2014.

So far, credit card companies have told the high-end retailer that about 2,400 cards from Neiman Marcus customers have been used in fraudulent transactions linked to the breach. This is the most detailed accounting of the incident, which occurred between July and October of 2013, the firm has released to date. Neiman Marcus said online customers were not affected by the intrusion and sensitive information such as social security numbers, birth dates and PIN numbers were not taken in the cyberattack. The scope of the Neiman Marcus attack is far more limited than a similar breach at Target, where a December breach might ultimately affect more than 100 million customers. Though Neiman Marcus says it has “no knowledge” of a connection to the Target breach, the incidents are striking similar.
