Cracking a Wifi (WEP) Password :-

========================
-METHOD 1 :: Getting Past a Log In Password.
----------------------------------------------------------------
1) Boot the computer in safe mode.
2) Click “Start”.
3) Click “Run”.
4) Type in “control userpasswords2”. [1]
5) Change passwords for any account.This is probably going to be obvious to the user, so you may have to tell them a little white lie. Try something along the lines of: "Oh, I hear computers glitch like that sometimes. You can always type in recoverpassword if you get locked out and then set a new
6) Reboot the computer.
-METHOD 2:: Getting Remote Access
--------------------------------------------------
1) Download the program LogMeIn. There is a free version, though you can purchase a subscription if that better meets your needs. [3]
*.The program will need to be downloaded to the computer you intend to remotely view or use. This makes it useful for gaining access to your computer if it is stolen or for checking up on your teen’s daytime activities during the summer.
*.You will have to make an account with the LogMeIn website in order to use the software.
2) Log in to the website.Log in to LogMeIn’s website.
3) Navigate to the “My Computers” page. It should open automatically when you sign in.
4) Add the computer you intend to remotely access.You will see an “Add computer” button on the page. Click that and fill in the info for the computer you intend to access.
5) Click the name for the computer once it’s added.
6) Log on to the computer.This means you’ll have to know the username and password for the account you’re trying to access or view.
7) Click “Remote Control”. If you’re trying to be sneaky (such as to spy on the user), try to move the mouse as little as possible and don’t click on anything.
8) Log out when you’re done.
-METHOD 3:: Cracking a Wifi (WEP) Password
------------------------------------------------------------
1) Download the necessary programs.You will need 2 programs to make this hack work: CommView (which will be used to look for vulnerabilities in the network you’re trying to access [4]) and AirCrackNG (which will break the security key itself)
*.Make sure your computer’s wireless adaptor is compatiblewith CommView.
2) Find a Network. Use CommView to scan for wireless networks. Choose a network with a WEP key and a decent signal.
3) Filter the search to that network. Right click on the network you
want to access, select “Copy MAC address”, go to the Rules tab, then MAC Addresses, enable MAC address rules, then click Action→Capture→Add Record→Both. Paste in the MAC address.
4) View Data packets.Sort out the Management (M) and Control (C ) packets so that you are only viewing the Data (D) packets.
5) Save the packets. Go to the Logging tab and enable auto saving. You may need to change the settings on the Directory size and File size. Try 2000 and 20, respectively.
6) Press the “Play” button to begin collecting. Wait until you have at least 100,000 packets.
7) Click “Concatenate Logs” under the Log tab. Make sure all of the logs are selected.
8) Export the logs. Go to the folder where the logs were saved and open the log file. Click File→Export→WireShark/tcpdump format and save it where you can find it easily.
9) Open the newly created file with Aircrack. Start Aircrack and choose WEP. Open the file and click “Launch”.
10) Enter the index number. When the command prompt opens, you’ll need to enter the index number for the target network. It is probably 1. Hit enter and wait. If it works, the key will be shown..!
