The 2004 edition of the WorldWide WarDrive (WWWD) — "an effort by security professionals and hobbyists to generate awareness of the need by individual users and companies to secure their access points" — has been announced for 12-19 June, 2004.
The WorldWide WarDrive has teamed with the Wireless Geographic Logging Engine (WiGLE) to provide real time maps and statistics as data from each area is uploaded. (…) and the Church Of WiFi is proud to announce that an updated version of WarKizNiz is available here. WarKizNiz accepts input from Kismet log files and converts them into NetStumbler .ns1 format. Coordination of drives throughout the world is done at the WorldWide WarDrive Forums. As in the past, discussions pertaining to the WWWD can also be conducted on the WarDriving mailing list. New for WWWD4 is the creation of a mailing list devoted solely to wireless security issues. To join this list, hosted by Michigan Wireless go here.
