For once I am posting a question since it is something I have yet to be able to answer properly, but the bug keeps itching at me to answer it.
How do you physically locate a wireless user? Pretend you have a wireless network and someone has been getting in. Other than getting lucky and walking around, how do you locate someone efficiently?
Now, I know expensive and expansive solutions exist for larger campus-type wireless implementations to locate users using information on their signal strength and triangulation between overlapping wireless coverage. But what about for your average techie joe who wants to do this? Is there any software and non-expensive hardware that can help?
I also know that I could attempt attacks against a laptop and see if I can turn on an annoying WAV file and increase the sound…but that’s a bit too intrusive and variable.
I’ll likely troll a few forums and IRC chans looking for this information over the course of the next few months as I’d really like to answer it.
