World Wide Wardrive finds most access points unprotected: The fourth week-long international wardrive found 288,000 access points in their survey, more than 50 percent of which had no security enabled. Since these were passive scans, it's impossible to tell whether those access points were inside or outside corporate firewalls, and thus not open portals, but it's likely that the overwhelming majority were just plain open. Nearly 30 percent had the default SSID or network name set.
