INTRODUCTION :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 . Download Links : 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 . 1.Aircrack-NG GUI Get it from here :http://www.aircrack-ng.org/ 2.Commview for Wifi Get it from here :http://www.tamos.com/download/main/ca.php 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 .
STEP 3 (Choosing the Network (a) ) : 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. 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 .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 . If you have any questions or having problems post a thread il reply . This is a simple tutorial . There is more advance using the rules and stuff but I havnt used it yet . This worked for me . Hope you found it useful . Took a lot of time . Please leave your feedback. Happy Hacking !
