This document provides instructions for cracking Wi-Fi encryption using Backtrack 5 R3 in 3 steps: 1. Set up a virtual machine using VMware to securely run Backtrack 5 R3, an operating system for digital forensics and penetration testing. 2. Connect an external Wi-Fi receiver to the virtual machine and use airodump-ng to search for Wi-Fi networks, putting the adapter in monitor mode. 3. Use the Reaver tool to launch a brute force attack against any networks found using WPS to crack the WPA encryption key in 3 steps or less.

2. ENCRYPTION IN WI -FI
WEP(wired equivalent privacy)
 IT is an easily broken security algorithm for IEEE 802.11.
 WEP, recognizable by the key of 10 or 26 hexadecimal digits

4. WPA(WI-FI PROTECTED
ACCESS)
WPA available in 2003.
This replaces the cyclic redundancy check
that was used by the WEP standard

6. TOOLS FOR CRACKING
 VMWARE
 ISO FILE OF BACKTRACK5 R3
 External Wi-Fi Receiver

7. VMWARE
Secure way to run multiple operating
systems at the same time
It is an integral component of any
serious technical professional’s toolkit.

8. BACKTRACK
Backtrack is an operating system based on
the Ubuntu GNU/Linux distribution aimed at
digital forensics and penetration testing use. It
is named after backtracking, a search algorithm.
The current version is Backtrack 5, code name
“Revolution.”

9. WI-FI BOOSTER
Make broadband wireless in possible coverage.
Strengthen radio signal to increase the effective
range and coverage area for Wi-Fi communication.
Install easily, just plug in and play.
Save lots of wiring costs.
