On Friday, upscale retailer Neiman Marcus revealed that it had been the victim of a cyberattack during which hackers managed to obtain some customer data.
Neiman Marcus said it learned of the breach when its credit-card processor alerted it to unauthorized charges on consumer accounts. Those customers had made charges at Neiman Marcus stores. Neiman Marcus indicated that it was advised of the problem in mid-December and confirmed the attack on Jan. 1. Sources said that less than one million charge cards had been compromised in the Neiman Marcus data breach, the Wall Street Journal notes.
Neiman Marcus indicated that it was still looking into the data breach and had “taken significant steps to further enhance information security.” The Neiman Marcus data breach comes just weeks after discount retailer Target (TGT) announced that its store payment systems had been hacked, compromising as many as 110 million debit and credit cards.
Sources tell Reuters that hackers may have targeted at least three other prominent American retail chains over the holiday shopping season, apparently preying on mall outlets and using point-of-sale data breaches similar to the Target incident. Those attacks are thought to have been coordinated by hackers based in Eastern Europe and were smaller than the attacks on Target and Neiman Marcus. The three retailers involved in those attacks have not yet been identified.
