The Process:

• Identify the Network
• Collect Packets from the Network
• Crack packets

Tools we will be using:

1. BackTrack LiveCD Distro
2. Kismet wireless analyzer
3. Aircrack-ng suite

Step 1 :

Our first step is to identify the network we will be targeting and to gather information about it. For this we will be using Kismet for Linux. If you have not already read the Kismet tutorial do so now. Otherwise, put your wireless card in monitor mode and open Kismet.

Step 2 :

With Kismet running select the targeted network by pressing 's' then 'c' to sort the discovered networks by channel, then highlighting your target and pressing 'enter' this will bring up information about the targeted access point.

Step 3 :

Record the MAC address of the access point, the type of encryption it uses, and the ESSID of the access point. Close this information window by pressing 'x'

Step 4 :

From the main menu press 'c' to list the discovered clients associated with the access point. Record one or two of their MAC addresses for use later.

Step 5 :

Close Kismet by pressing 'shift+q' and move on to the next part of the tutorial
