wardriving
The act of driving around in a vehicle with a laptop computer, an antenna, and an 802.11 wireless LAN adapter to exploit existing wireless networks. Set on promiscuous mode, the wireless adapter, typically a NIC, will receive packets within its range. Wardriving exploits wireless networks that have ranges that extend outside the perimeter of buildings in order to gain free internet access or illegal access to an organization��s data. One safeguard against wardriving is using the WPA encryption standard.
