NEW YORK (AP) -- The security breach that hit Target Corporation during the crucial holiday season seemed to be part of a broader scam that affected several retailers. That's according to a report published by a global cyber intelligence firm that works with the U.S. Secret Service and the Department of Homeland Security.
The report released Thursday by iSight Partners of Dallas, Texas offers more insight into the breach at Target. Hackers affected 40 million credit and debit card accounts and stole the personal information of as many as 70 million customers.
The report confirms that a malicious software that infiltrated the point of sale system at the registers was "almost certainly derived" from BlackPOS, a crude but effective software product.
Last week, Neiman Marcus said it was hit by a security breach over the holidays.
