Big-Box Breach: The Inside Story of Wal-Mart’s Hacker Attack

Posted on October 13, 2009 by Dissent

Kim Zetter reports:

Wal-Mart was the victim of a serious security breach in 2005 and 2006 in which hackers targeted the development team in charge of the chain’s point-of-sale system and siphoned source code and other sensitive data to a computer in Eastern Europe, Wired.com has learned.

Internal documents reveal for the first time that the nation’s largest retailer was among the earliest targets of a wave of cyberattacks that went after the bank-card processing systems of brick-and-mortar stores around the United States beginning in 2005. The details of the breach, and the company’s challenges in reconstructing what happened, shed new light on the vulnerable state of retail security at the time, despite card-processing security standards that had been in place since 2001.
