Is it possible to detect failed logins on the hotspots you create with your windows/linux laptops? So you can detect some dumb brute force/guessing attempts? For example, a log like this:
TIME DATA - WIFI HOTSPOT LOGIN FAILED - MAC ADDRESS INTRUDER - PASSWORD THAT WAS TRIED
As for the password part, lets take wep for example:
- The client sends an authentication request to the Access Point.
- The Access Point replies with a clear-text challenge.
- The client encrypts the challenge-text using the configured WEP key, and sends it back in another authentication request.
- The Access Point decrypts the response. If this matches the challenge-text the Access Point sends back a positive reply.
Since you send the challenge yourself, in theory, you will be able to retrieve the plaintext challenge. It should be also be possible to get this response, when your own laptop is the access point, right? But than comes the questuion: what is the decryption algorithm?
