It couldn’t have happened at a worse time for a retailer. Target informed shoppers that if they charged an item at Target stores between Nov. 27 and Dec. 15, their credit and debit card accounts may have been compromised—as much as 40 million cards in all.
While online shoppers typically have been the victims, this time hackers went through the physical checkout systems inside every Target store—about 2,000 stores, 1,797 in the United States and 124 in Canada. It’s possible that every shopper who swiped a credit card or entered a pin number at the point of sale had their information stolen.
Barbara Endicott-Popovsky, director of the Center for Information Assurance and Cybersecurity at the University of Washington told TIME Magazine that hacking “is a business. The general public would be shocked and amazed by the size of the problem.”
