Half of more than 3,000 retail stores that a wireless security company secretly monitored at major shopping areas in the U.S. and Europe use wireless data systems vulnerable to hacking, the company said Thursday. The data that stores routinely transmit on wireless networks include credit card and Social Security numbers and other sensitive customer information. AirDefense, an Atlanta-based maker of security products for wireless data systems, found that about 25 percent of the stores' 4,748 wireless access points were exchanging data with no encryption at all.
