How To Hack Wireless WEP Protected Netwotks Using Backtrack!

Before even starting to read this make sure you have compatible wireless adapter!

For this tutorial you will need backtrack, you can download from here (I am using Backtrack 5 for this tutorial).
Once downloaded you can either burn the .ISO to a cd and boot it, or you can make a frugal install using UNetbootin.


Ok, when you successfully start backtrack go to Applications > Exploitation Tools > Wireless Exploitation Tools > Wlan Exploitation > gerix-wifi-cracker-ng.



Once the program is started go to "Configuration" tab.



Press "Set random MAC address"



Then "Enable/Disable Monitor Mode"



Now press "Rescan networks" and choose the slave.



Then press the "WEP" tab, you will see the "Start Sniffing and logging" button, press that. A new window will pop-up that's airodump console. Look at the "Data" you will need 10000-20000 Data/IV's to crack the wep key (Sometimes more).



Now we are gonna speed up the proccess of getting necessary Data/IV's. Press the "WEP Attacks (No-Client)"



Then press "Associate with AP using fake auth"



A new shell console will pop-up, wait untill it asks you "Use this packet? Type "Y" and hit enter.



Now press "Fragmented Attack" again a new shell console will pop-up and it will ask you "Use this packet? Type "Y" and hit enter.



Wait 20-30 seconds until you get enough Data/IV's to crack the WEP key.



Once you get enough Data/IV's go to "Cracking" tab and press "Aircrack-ng Decrypt WEP Password" New shell console will pop-up, when finished decrypting it will look something like this.
