Wardriving was the practice of driving around an area looking for wireless networks that are open. Once detected, the sites are recorded by marking chalk symbols on the nearby pavement (sidewalk) or wall – a process referred to as warchalking. Wireless networks are detected by using sniffing software such as NetStumbler.
