|With cities deploying unsecured municipal Wi-Fi networks to encourage visitor use, these signals may unintentionally reach a retailer’s office or store premises. Therefore, anyone with electronic devices such as notebooks, smart phones or PDAs using wireless LAN can attach to unsecured neighbouring wireless LANs. This enables the user to gain full access to the retailer’s network. After retrieving retailer or consumer information, unscrupulous employees could then use or sell the highly confidential information.
