The U.S. Secret Service has confirmed that it is investigating a massive data breach at major retailer Target that could involve millions of shopper's credit and debit card information.
According to Krebs on Security, which has broken high-profile security incidents in the past, the breach began on Black Friday, the busiest shopping day of the year, and involves the theft of information from nearly all of Target's brick and mortar stores in the U.S.
Target has 1800 stores in the nation. The report claims online purchases do not appear to be involved, just the data that would allows thieves to create counterfeit cards and even possibly withdraw from ATMs using stolen PINs.
Krebs reported that the breach was ongoing from Black Friday until December 15th.
Target, Mastercard and Visa did not comment on the initial report.
