The security breach at Target over the holidays apparently was part of a sophisticated international hacking campaign planned against several retailers, according to a report from federal and private investigators.
The report, which was sent to financial-services companies and retailers, revealed that parts of the computer code used in the Target hack had been on the Internet's black market since last spring and were partly written in Russian, sources told the Wall Street Journal. These details indicate the attack may be tied to organized crime in the former Soviet Union, according to the newspaper.
"What's really unique about this one is it's the first time we've seen the attack method at this scale," Tiffany Jones, a senior vice president at iSight, told the Wall Street Journal. Dallas-based cybersecurity firm iSight has been working with the U.S. Department of Homeland Security on investigating the incident.
On Thursday, Neiman Marcus said there is no indication its recent security breach was related to Target's.
