Getting Wpa Password With Jasager

Recommended Posts

Hi guys.

Just got this idea last night, so I didn't have time to check if it is really possible. But here it is:

Device 1 - Is there a "this and this" -network aroud?

Jasager - Here I am, connect to me!

---At this point.

what if we make jasager ask's for a password for "this and this", would device1 give up the password?

In my own little head, I think you could get any password to any wifi, even wpa-psk or wpa2. Just deauth the target

and ask the password. Couldt it be this simple?

Tell me what you think?

that's what aireplay does with the aircrack-ng suite of tools. the only way to crack WPA2 is to capture the handshake after a deauth and bruteforce it.... just use reaver now :)

No, that wouldn't work as the password is never shared, authentication is done based on encrypting random strings called Nonces. I send you one and you encrypt it and send it back, I check that what you sent me matches what I get when I encrypt it. And then vise versa. If we both get what we expect then authentication is successful.

By emulating a WPA(2)-PSK AP it is possible to extract enough information out of the client to perform a brute force attack on the PSK, see my Wifi Honey script and the talk from Vivek that it is based on for more information. http://www.digininja.org/projects/wifi_honey.php
