more Wardriving...
I just talked to a buddy of mine about the wardriving I've done around the Bay Area (
http://flatblog.dhs.org/wireless) and he was totally amazed by how much can be done with just a laptop and a wireless card. I always thought i was the one that was behind the times and that i was jumpiung on this bandwagon way later than everyone else. Turns out that some people still don't know. And that's cool. It gives people like me a chance to explain. Or better yet point you to the right website and save myself typing.
So here:
http://www.wardriving.com
It talks all about what it is and how it is done.
And this one:
http://www.netstumbler.com
You are bound to hear about this software soonber or later.
Anyway, remeber, wardriving is not a crime as long as you only DOCUMENT the existing Wireless Access Points, and not actively try to hack into WiFi networks. So wardrive carefully and remeber what we always say: "Don't get eliminated!"
