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 .
![[Image: 3.png]](http://imgsrc.in/images/3.png)
STEP 5 (Capturing the Packets) :The windows should close now and you should see that CommView has started Capturing Packets .
![[Image: 4.png]](http://imgsrc.in/images/4.png)
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
![[Image: 9gyg.png]](http://imgsrc.in/images/9gyg.png)
Click on the LOGGING Tab .
Check AUTO-SAVING
In the Maximum Directory Size : 2000
Average Log File Size : 20
![[Image: 7.png]](http://imgsrc.in/images/7.png)
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 !

ReplyDeletenow what must i do?
Open AirCrack then what?
Aircrack has chewed through the packets and is now asking, "Index number of target network ?" Where do I find that? What do I enter there?
ReplyDeleteNever mind. It's all here:
Deletehttp://hackingplayground.blogspot.com.au/2010/10/hacking-wifiwep-encrypted-networks-with.html
After installing commview u must tell the app to save the logs automatically, you tell where do u want the NFC file
ReplyDeleteIn the channels tab see for encryption section, after about 20K 25K u d be able to hack.
Open the NFC file > export > CAP file
Aircrack > browse CAP file
Launch
It'll ask something, type 1 - 5 until it finds the key
wher can i see the password in the command???
ReplyDeletecommview does not support in intel(R) centrino (R) n100

ReplyDeleteGreat Nice ... do you have skype ID please?
ReplyDeleteits great it worked for you but i cant press the play button because it is blur and the play command is not available
ReplyDeleteI am getting " Index number of target network " what is this and what do I do??? Please help, everything so far has gone according to steps. cpdigicomm@gmail.com
ReplyDeletenot work 4 me, it fake
ReplyDeleteYou need a certain WIFI card, its not fake. Read the Aircrack-Ng page.
ReplyDeletelol it should work. if it does not its your fault. Figure it out! you probably have a bad wifi card!
ReplyDeleteTHANKsssssssssssssssssssssssssssss
ReplyDeleteThis must be the slow method, in linux it takes about 4-10 minutes... 5-6 hours ? wth lol. I recommend backtrack though, it's a live cd, and it's easier.
ReplyDeleteAlso, for all the noobs out there, you can't use an internal wifi card for this method, meaning your laptop computer... You have to buy an external dongle, or perhaps a cantenna. I myself prefer a directional antenna rather than an omni-directional antenna. You'll be set !
ReplyDeleteworks perfect with integrated wlan card on laptop! 30 mins. Thank you!
ReplyDeletethere are 2 downlaods for the Aircrack-NG GUI.....1 for windows and 2 for soure....which to download?????
ReplyDeleteIs this method successful? I recently found there is a WEP network so I would like to try this on it!
ReplyDeletehi...When i clicked on the link for downloading aircrack, i found many options like sources, windows, etc. which one should i choose?
ReplyDeleteafter 14 hours of collecting data,7000 IV's were collected and you need at least 1,500,000 IV's to hack a 128 but key with around 95% accuracy. If you do not have a NIC that can inject packets, this can take you weeks or more and the file sizes need a ton of space and RAM to compute the mass calculations. Good luck without a NIC card that can inject packets.
ReplyDeletehow many ivs are required to crack, i have created nearly 100 .cap file but when i cilck launch button the cmd prompt is not opening, filesize is too long,plz tell me the solution to this problem
ReplyDeletewhen i open the aircrack folder i dont see the folder Bin ...how can i install this???please help....
ReplyDeletemy computer shows thi wifi network but commview does not scan it. any idea?
ReplyDeleteWhat should happen when i use aircrack and open the .cap file. I launched. the cmd window using launch button what should happen next.
ReplyDeleteworked great for me...i now comment using the hacked network...thx a lot
