Wireless snooping

[straykat777]

Is there software that can be sued to see if there is someone on my wireless network and if there is a way to see what they are looking at. I believe Darren had something in a episode but not sure.

Thanks

Drop the Interceptor between your AP and your internet connection then watch the traffic, if you see stuff that isn't yours then someone is using it.

If you turn on WPA2 and set a decent password then no one else should be able to use it.

look at the ip addresses in the router and compare to the devices you use

Yeah its called airodump-ng and is available on the Back-tack live c.d.

Open a console in Back track and do the following at the prompt.

airmon-ng stop ath0 ( change ath0 to what ever fits your wireless card)

airmon-ng start wifi0

airodump-ng ath0 -w NAME YOUR SAVE FILE HERE -c CHAN NUMBER

Then all ya have to do is look at what mac addy's are associated to your AP if they don't match your wifi cards its safe to assume someone is stealing your shit.

For less headaches I would do as digininja suggested and change to WPA2 (problem solved).
