Target stores report a possible breach in their credit card information that may involve up to 40 million credit and debit card accounts. It is feared that their customer account information may have been stolen.
The discovery narrows the breach during the peak shopping days of Nov. 27 through Dec. 15.
Once the breach was discovered, Target officials said they contacted authorities and financial institutions. In order to conduct an investigation, Target enlisted a third-party forensics team. CBS News reports the Minnesota based retail chain was victimized by thieves who stole data from credit card machines in nearly all of its stores nationwide.
According to CBS, American Express is aware and is in the process of putting fraud control systems in place. VISA and MasterCard did not comment. The Secret Service is overseeing the investigation because they handle financial crimes. Only those Target customers who shopped in the store could be affected and does not include online Target customers according to an online report.
Target released a statement that said it "... is working closely with law enforcement and financial institutions, and has identified and resolved the issue".
