Based on former Washington Post writer, Brian Krebs, the breach is originally believed to have lasted between Thanksgiving (November 28) through Friday, December 6 or even the 15th. Combined with the extremely large amount of time that cyber criminals obtained entry to what’s reported to be debit and credit card information on countless Target shoppers, the breach impacted brick-and-mortar shoppers too.
According to unnamed sources at credit card issuers, cyber criminals took the information stored on the magnetic strip on the back of credit and debit cards, affecting shoppers at virtually all of Target’s major stores nationwide.
“The breach window is definitely expanding,” mentioned one anti-fraud analyzer from a top 10 U.S. charge card provider who asked to stay anonymous. “We can’t say for sure that all stores were impacted, but we do see customers all over the U.S. that were victimized.”
Kerbs went on to say “Minneapolis, Minn. based Target Brands Inc. has not responded to multiple requests for comment. Representatives from MasterCard and Visa also could not be immediately reached for comment”.
