How to crack WEP using Linux backtrack 3
  

I like to do experiments with my devices and computers. I have one D-Link wireless router and want to check its security. Today I enabled its WEP security and decided to hack or crack this using my backtrack 3. But the problem is that I am unable to get the steps to do so. Can you tell me how to crack WEP using Linux backtrack 3?

Re: How to crack WEP using Linux backtrack 3

To crack WEP, you'll need to launch Konsole, BackTrack's built-in command line. Now run the following to get a list of your network interfaces:

Code:
airmon-ng
Then run the following four commands:

Code:
airmon-ng stop (interface)
ifconfig (interface) down
macchanger --mac 00:11:22:33:44:55 (interface)
airmon-ng start (interface)
for more information see this.

You can also use Wi-Fi WEP Key Generator to crack WEP passphrase. The Wi-Fi WEP Key Generator Utility is used to quickly and easily create more secure WEP keys than can be created by using the built in PassPhrase generators contained in Wi-Fi networking Equipment. Wi-Fi WEP Key Generator runs under Windows 98/98se/NT/2000/XP.

WEP Key Generator generates a random WEP key. With WEP key Generator you will be able to generate a valid WEP key from a 5, 13, 16 or 29 characters long phrase. Select the bit key length to generate and press the corresponding button. You can also generate a custom WEP key based on your own pass phrase or other input.
