How To Hack Wi-Fi WEP Key

Posted: January 12, 2012 in Uncategorized

NTRODUCTION :

Many Windows users here are struggling to hack WiFi networks because most of the tutorials are based on BackTrack and other Linux Tools .

 

Im just sharing the method to Crack WiFi networks using WEP security protocol . The WEP is a very vuarable to attacks and can be cracked

easily .

It takes about 5-6 hours if the password is weak a high signal of the WiFi network you are going to hack and you have sometimes 10-12 for more complicated passwords and if the WiFi signal of the Network is weak .

The time taken also changes if the WiFi network you are going to hack has many other clients already accessing it .

 

 

You will be using two tools .

1.Commview for WiFi :

You will use this tool for capturing the packets sent and recieved through the Access Point you are going to hack .

The more packets you capture the better chances of cracking the password .

You will need more than 1,00,000 minium 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 WiFi cards are supported by Commview only in Windows 7 so i suggest you install Win 7 in ur Virtual Machine if ur card isnt 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 : You need to run this as administrator .

 

I have provided links for both the software below .

These are the links to the official website of the tools .

Some Anti Viruses might detect Aircrack as a virus . It is a false positive .

GET READY TO CRACK :

 

 

STEP 1 :

1.Install CommView for WiFi . It doesnt 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 WiFi when using CommView .

 

STEP 2 :

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

A new window should pop up now .

Click on the START SCANNING button .

STEP 4 (Choosing the Network (b) ) :

Click on the WiFi network you want to hack in the Right Coulumn and Click on CAPTURE.

STEP 5 (Capturing the Packets) :

The windows should close now and you should see that CommView has started Capturing Packets .

 

Spoiler (Click to View)

 

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

Spoiler (Click to View)

 

Click on the LOGGING Tab .

Check AUTO-SAVING

In the Maximum Directory Size : 2000

Average Log File Size : 20

 

Spoiler (Click to View)

Now CommView will automatically Start Saving packets in the .ncp 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 once 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->Wireshark/TCP dump format .

Aircrack Part :

 

 

Now for the Second Part Cracking this is very simple .

 

Just open the Aircrack Folder->Bin->Aircrack-ng GUI.exe

 

Choose the .cap file and you should be able to do the others .
