Quote:A warning for anyone who has shopped at Target stores since Thanksgiving: Your debit and credit card information may now be in the hands of hackers.
The Secret Service has confirmed thieves have stolen an unknown number of Target customers' payment information, which could affect millions who have shopped there, starting on the busy Black Friday weekend.
The breach reportedly involves nearly all Target stores nationwide, and may have continued until Dec. 15.
Investigators believe the data stored in the cards' magnetic strips was hacked at the cash registers.
Hackers may aim to sell the stolen information wholesale on the black market to people who use it to manufacture phony credit or debit cards. Criminals can then use those fake cards to buy gift cards and eventually convert them into cash.
