In hindsight, the number of security breaches and attacks during the holiday shopping season seems relatively low given how many shoppers are taking to their smartphones and tablets with their credit cards these days.
It's actually no laughing matter given how long the breach has possibly gone undetected.
According to former Washington Post staffer Brian Krebs, the breach is initially thought to have lasted between Thanksgiving (November 28) through Friday, December 6 -- or possibly even up to December 15.
Along with the incredibly long window of time that cyber criminals had access to what is said to be credit and debit card data on millions of Target customers, the breach affected brick-and-mortar shoppers too.
Based on unnamed sources at credit card companies, cyber criminals tapped into the data stored on the magnetic strip on the back of credit and debit cards, affecting customers at nearly all of Target's big box stores nationwide.
