Target & Neiman Marcus Hacks

February 27, 2014

Follow up on the December announcement by Target that account information for 40 million credit and debit cards had been stolen in a sophisticated attack on the point of sale systems.  The retailer admitted in January that up to 110 million customers were affected   The Neiman Marcus attack now appears to be unrelated to the hack on Target.  Originally estimated at 1.1 million cards, it now appears that fewer than 350,000 cards were exposed.  The retailer reports that 9,200 have been used fraudulently since the attack.  The bad news is that the hackers were apparently in the system for 8 months and set off 60,000 alerts without getting caught.
