Who is a wardriver?

A wardriver is someone who accesses an unsecured wireless connection through a PDA or laptop in a moving vehicle. It�s derived from the word wardialling from the film WarGames. Other related concepts are warbiking (accessing a wi-fi connection on a motorbike or bicycle) and warwalking/ jogging (doing the same while on foot). While there are several softwares to enable wardriving, they can be easily misused as well. In India, terror e-mails were sent by wardrivers who accessed an unprotected wireless connection.
