Your friendly, neighborhood UPS store might have been hacked. UPS just confirmed that 51 stores across 24 states in the United States had malware capable of recording credit card information and sending it to third parties on its in-store cash registers. If you swiped your card at any of these, your details are probably being sold on the black market right now. UPS started investigating its system at the end of July after the Department of Homeland Security issued a warning to retailers about hackers trying to target remote access systems designed to allow employees to access corporate networks from afar.
