Re: How to track down a wireless hacker

["Mathieu CHATEAU" <gollum123 () free fr>]

Hello,

He may also just bought a PCMCIA or usb wifi network card in any shop 
(without any track then).
If you have the mac address, you may try to identify the manufacturer:

How do they know they were hacked ? Do you know what interest the hacker ?
You may set up a trap, with honeypot & co to collect data. He may be enough 
confident to retrieve pop3 mail or any thing cleartext that help identify.

Port mirroring may help to collect data.
