Report: Target's Big Credit Card Hack Might Involve Even More Retailers

The Wall Street Journal reports that Verizon Communications is investigating similar security breaches at two more as-yet-unnamed retailers that occurred around the same time as the massive Target credit card hack late last year. The two retailers affected by the newly-discovered attack have not yet announced the event to customers.

Verizon's Bryan Sartin did not directly link the newly-discovered hacking events to the Target breach. But in an interview with WSJ, he hinted that the same entity might have been involved in all three retailers' attacks: "The findings already substantiate a very real link between these later situations and something that recently happened." People familiar with the investigation have confirmed to WSJ that Sartin's team is investigating the Target attack.

The newest round of attacks was uncovered by the U.S. Secret Service. The retailers involved then called in Verizon's investigative team sometime last week. [WSJ]
