Protecting you wireless networks a bit more against wardrivers

["Moser Max" <MMoser () 3gmobile ch>]

Hi all,

Now its time to release some informations i found during the development
of the new Wellenreiter decoding engine. 

The ESSID of a wireless network could consist of any chars (not only
simple ASCII) and should have a length up to 34. So it is possible to
raise your protection against wardrivers in a very simple way:
 
           -->  Use only non-printable chars in you ESSID <--

That's it. How would you display those in a sniffer tool? In a report?
:-). I guess most of the wireless scanners have now a real problem :-).

I hope this makes the world a bit better. Don't think now this is a
"Big" protection,
plan and implement your networks/protection like wireless is a complete
open/shared environment is the best protection ever. 

Btw. I still looking for a security job in Switzerland, so if someone
got a contact for me, please drop me an email.

Greetings Max Moser
