According to the Associated Press, if you've used a credit card or debit card to shop at Target recently, you should check your statement. Target says information from up to 40 million customer accounts may have been stolen. That information may include your name, account number and the three-digit security code on the back of your card. Target says the breach occurred between the day before Thanksgiving and December 15th. Anyone who suspects unauthorized use should call the company at (866) 852-8680.
