Un secured AP's

sirlinux

My laptop came on the other day in my bag on the way to work walking across town, during that period it had managed to sign onto 2 different wireless networks and logged on msn messenger!! Didnt even realise it myself until people asked why i had been signing in and out of messenger early in the morning. How many people have unsecured AP's out there!!

if you're running windows get netstumbler
http://www.netsumbler.org, and you can scan for AP's with most 802.11b/a cards.

If you're running linux you can use the vastly superior kismet,
http://www.kismetwireless.net
which as well as doing everything netsumbler does, also detects cloaked (beacon packet off) networks, client traffic, ad-hoc networks. It can also dump packets in a format suitable for network analysers such as etheral, and the newer versions crack WEP without having to export it to an external program.

Kismet's also entirely passive, which I've read netstumbler isnt.

town sure is full of APs at the moment - i've counted 15 on my travels from d15 to d2, about 3 months ago - no doubt its expanded even further since then.
