Programs Required:
- Wireshark
- Aircarck-NG GUI
Steps:
-
Install Wireshark. Just allow it to install the needed drivers and you are good to go to the next step.
-
After the application is installed ,open it.
-
You will be prompted to a new window. Click on the Start Scanning button.
-
All the available networks around you will be shown. Just click the network you want to get the password, and click on “Capture”. NOTE: this will work for WEP networks only!
-
Now the newly opened windows will be closed and you will be able to see that Wireshark has started
capturing the packets. -
Click on Settings> Options> Memory Usage. Change the value of maximum packets in buffer to
20000
. -
Now you can click on the logging tab. Select “Auto Logging”. Enter 2000 in the “Maximum Directory
Size” and 20 in the “Average Log File Size”. -
Again go to “Logging” tab and select “Concatenate Logs” to join all the split logs of 20 MB we just created. And now we have one *.ncf file.
-
Open the *.ncf file that we just got form the above Concatenation step.
-
Click File> Export> Wireshark/Tco dump format. This will create a .cap file
-
Go to the Aircrack application folder and then traverse to the bin file inside. Double click on Aircrack-ng GUI.exe in the application and select the *.cap file we just created in step 10.
-
And that’s it! If you have sufficient data to crack the password, you will get the password. It is advisable to proceed from step 8 to 11 only after receiving enough packets. You will need a minimum
of 100000 packets to start the cracking. So after step 7, it is advisable to leave the system alone for 2- 3 hours and then proceed to the further steps!
Happy learning!
