Hacking Wifi Networks On Windows

Hacking Wifi Networks On Windows
Note: This guide is only for knowledge purpose

Introduction:
Many Windows users here are struggling to hack Wi-Fi networks because most of the tutorials are based on Backtrack and other Linux Tools. I’m just sharing the method to Crack Wi-Fi networks using WEP security protocol.
This only for testing your own Wi-Fi network . I am not responsible for
anything that happens due to this.

TOOLS REQUIRED:

1. Commview for Wi-Fi:
You will use this tool for capturing the packets sent and received through the Access Point you are going to test  .The more packets you capture the better chances of cracking the password .You will need more than 1,00,000 minimum packets to crack the password .The packets will be captured in the .ncp format .
You will use this tool to convert the .ncp to .cap.
NOTE: Some Wi-Fi cards are supported by Commview only in Windows 7 so i suggest you install
Windows 7 in your Virtual Machine if your Wi-Fi card isn’t supported.

2. Aircrack-Ng GUI:
You will use this tool to crack the password of the Access Point using the .cap files you obtained from the Commview application.

NOTE:
1. You need to run this as administrator.
2. Your Antivirus Might Detect it as a virus. It is a false positive.

The Testing Process:

STEP 1:
1. Install CommView for Wi-Fi. It doesn’t matter whether you install it in VoIP mode or Standard mode. I used VoIP.
It automatically installs the necessary drivers. Allow it to install.
NOTE: You will not be able to connect to any Network using Wi-Fi when using CommView.

STEP 2:
2. Click on the PLAY ICON in the Left First.

STEP 3 (Choosing the Network (a)): A new window should pop up now.
Click on Start Scanning.

STEP 4 (Choosing the Network (b) ) :
Click on the Wi-Fi network you want to hack in the Right Column and Click on CAPTURE.
NOTE: This tutorial is only for WEP protected networks.

STEP 5 (Capturing the Packets):
The windows should close now and you should see that CommView has started Capturing Packets.

STEP 6 (Saving the Packets):
Now that the Packets are getting captured you need to save them.
Click on Settings->Options->Memory Usage
Change Maximum Packets in buffer to 20000
Click on the LOGGING Tab.
Check AUTO-SAVING
In the Maximum Directory Size: 2000
Average Log File Size: 20
Now CommView will automatically
Start Saving packets in the .nap format at a size of 20MB each in the specified directory.

STEP 7 (Concatenating the Logs):
Since you are capturing a lot of logs you will need to concatenate them into one file.
To do this go to Logging and click on CONCATENATE LOGS 
Choose all the files that have been saved in your specified folder and concatenate them.
Now you will have one .ncf file.

STEP 8 (Converting .ncf to .cap):
Now that you have one file with all the packets you need to convert it into .cap file for AIRCRACK to crack-
Click on File->Log Viewer->Load Commview Logs-> Choose the .ncf file
Now File->Export->Wire shark/TCP dump format.

Aircrack:
Now that we have captured the ivs and stored it in a cap file. We are going to crack it using aircrack.
We will use the GUI version of aircrack.
Extract the Aircrack zip file you downloaded.
Go to the bin and open Aircrack Ng Gui.exe.

STEP 2:
Choose the .cap file you got through CommView for Wi-Fi

STEP 3:
Click on Launch!
You will get this screen in cmd
Choose the target network .Ex: 1 if testwifi1 or 2 if testwifi2 and hit Enter.

STEP 4:
Just wait while aircrack is cracking the password.

STEP 5:
Aircrack has successfully found the password.
Now Connect to the Wi-Fi network using the key.
