WiFi Cracker – How to crack Wifi password (WPA,WPA2) using Backtrack 5

Backtrack 5 WiFi WPA 2 cracker
For educational purposes, in this article, we will see how to crack WiFi password using a famous WiFi cracker, Backtrack 5 R3, which can help patient people to hack even WPA and WPA2 security protocols.

Firstly, I want you to be aware of that our solution works only on the WiFi networks that WPS is enabled.
WPS is a common feature in almost all of the wireless router is produced in recent years. This feature allows a computer to connect to a wireless network through PIN entry without having to remember passwords that network.
It takes me actually 4 hours to more than 10 hours dealing with Backtrack 5 R3 to crack successfully WPA2 (WPS enabled).

4 Steps to Crack WiFi password using Backtrack 5

We are going to use Backtrack and Wifite. You need to be patient and some kind of luck.

Step 1: Download WiFi cracker tools

  • Download unetbootin.
  • An available 4GB USB
  • Download Backtrack R3

Step 2: Create Backtrack 5 Bootable USB

  • Run unetbootin, select backtrack 5.ISO at diskimage, then click on OK.

It takes a little while to finish the processing.

Step 3: Make the Laptop boot into Backtrack 5

In the rage of this article, we are going to deal with a virtual machine (VMware or Virtual Box). This method leads to better effectiveness to do directly with the Laptop. At for Macbook, keep holding the Option key to go to the boot menu. For Windows Laptop, go to Bios to make USB boot at priority.
Select “backtrack text – default boot text mode” to boot to backtrack OS.
