How To Hack A WiFi Network Both WEP and WPA Passwords 2012

Today ill tell you, how to hack WiFi Using Some Simple And Working Tricks You Can easily hack the WiFi network. I think you know that if you want to lock down your WiFi network, you will use WPA encryption because the WEP encryption is easy to crack. In this tutorial we will tell you how to crack WEP passwords, an older and less often used network security protocol. If the network you want to crack is using the more popular WPA encryption, See Below For Second Tutorial.

In This step-by-step tutorial, how to crack a Wi-Fi network with WEP security turned on.

Requirements For WiFi Hacking :-

1. Unless you’re a computer security and networking ninja, chances are you don’t have all the tools on hand to get this job done. Here’s what you’ll need: A compatible wireless adapter—This is the biggest requirement. You’ll need a wireless adapter that’s capable of packet injection, and chances are the one in your computer is not.

2. A BackTrack Live CD

3. A nearby WEP-enabled Wi-Fi network. The signal should be strong and ideally people are using it, connecting and disconnecting their devices from it. The more use it gets while you collect the data you need to run your crack, the better your chances of success.

4. Patience with the command line. This is an ten-step process that requires typing in long, arcane commands and waiting around for your Wi-Fi card to collect data in order to crack the password. Like the doctor said to the short person, be a little patient.

Crack That WEP

To crack WEP, you’ll need to launch Konsole, BackTrack’s built-in command line. It’s right there on the taskbar in the lower left corner, second button to the right. Now, the commands.

First run the following to get a list of your network interfaces:

airmon-ng

The only one I’ve got there is labeled ra0. Yours may be different; take note of the label and write it down. From here on in, substitute it in everywhere a command includes (interface).

Now, run the following four commands. See the output that I got for them in the screenshot below.


airmon-ng stop (interface)
ifconfig (interface) down
macchanger --mac 00:11:22:33:44:55 (interface)
airmon-ng start (interface)

How to Crack a Wi-Fi Network’s WPA Password with Reaver :-

Here’s the bad news: A new, free, open-source tool called Reaver exploits a security hole in wireless routers and can crack most routers’ current passwords with relative ease. Here’s how to crack a WPA or WPA2 password, step by step, with Reaver—and how to protect your network against Reaver attacks.

Requirement For WiFi Hacking :-

The BackTrack 5 Live DVD. BackTrack is a bootable Linux distribution that’s filled to the brim with network testing tools, and while it’s not strictly required to use Reaver, it’s the easiest approach for most users.

• A computer with Wi-Fi and a DVD drive. BackTrack will work with the wireless card on most laptops, so chances are your laptop will work fine. However, BackTrack doesn’t have a full compatibility list, so no guarantees. You’ll also need a DVD drive, since that’s how you’ll boot into BackTrack. I used a six-year-old MacBook Pro.
• A nearby WPA-secured Wi-Fi network. Technically, it will need to be a network using WPA security with the WPS feature enabled. I’ll explain in more detail in the “How Reaver Works” section how WPS creates the security hole that makes WPA cracking possible.
• A little patience. This is a 4-step process, and while it’s not terribly difficult to crack a WPA password with Reaver, it’s a brute-force attack, which means your computer will be testing a number of different combinations of cracks on your router before it finds the right one. When I tested it, Reaver took roughly 2.5 hours to successfully crack my password. The Reaver home page suggests it can take anywhere from 4-10 hours. Your mileage may vary.

How To Hack WiFi network :-

Step 1: Boot into BackTrack.

Step 2: Install Reaver

1. Click Applications > Internet > Wicd Network Manager
2. Select your network and click Connect, enter your password if necessary, click OK, and then click Connect a second time.

Now that you’re online, let’s install Reaver. Click the Terminal button in the menu bar (or click Applications > Accessories > Terminal). At the prompt, type:

apt-get update

And then, after the update completes:

apt-get install reaver

Step 3: Gather Your Device Information, Prep Your Crackin’

Find your wireless card: Inside Terminal, type:

iwconfig

Put your wireless card into monitor mode: Assuming your wireless card’s interface name iswlan0, execute the following command to put your wireless card into monitor mode:

airmon-ng start wlan0 Find the BSSID of the router you want to crack 

Step 4: Crack a Network’s WPA Password with Reaver

reaver -i moninterface -b bssid -vv 

For example, if your monitor interface was mon0 like mine, and your BSSID was8D:AE:9D:65:1F:B2 (a BSSID I just made up), your command would look like:

reaver -i mon0 -b 8D:AE:9D:65:1F:B2 -vv

After Doing This You Are Able To get The WiFi Password. If You Have Any Query.. POst in Comments
