EH-Net

im wondering how to get hidden SSID without any client associated with it ??

while i was scanning network around with airodump i got 2 networks like the same channel " 113 "

they are the only networks using this high channel number and with name like this <length 0>

just no name

and no clients connected to it ...so is there anyway to know what type of AP is this ?? or name ?

Well, you might be able to tell the type, based on the MAC address.  After all, if you're seeing it, at all, it must be sending out Broadcast packets, so those should have a MAC address in them, which you can compare to the lists and find vendors for, etc.

As for name, unless it's broadcasting it's name (which some do, some don't,) you won't likely find a name, without a client authenticating to it.

well ya right i forgot about that mac address part :) i'd try to figure it out

i wonder what kind of access points using channel 113 ?

i know that known channel from 1 - 11 ?

how is possible to be 113 ?

Higher frequencies, etc... 

Hmmmmm...  unsure about 113, however, if you do a little googling, on Wikipedia, you'll find the following:

I wrote a script that attempts brute force attack on the hidden ssid you could think about creating a list of ssid names based upon the OUI mac address part.

in the post you will find a video demoing how to use it
