Cracking WEP WiFi using the Raspberry Pi

About: WEP WiFi security has been debunked for years but thankfully for us there are still people who have never switched to the more secure WPA2 protocol. These are either older businesses who never invested in updating their security or have older equipment which is not compatible with the WPA2 security protocol. You will see how unsecured the WEP protocol is and how quickly it can be cracked. The Raspberry Pi I will be using is overclocked to 900 MHz so it will speed up the cracking process a little bit. I plan on writing a separate article on how the different overclock settings and how they compare.

Objective: To demonstrate how insecure the WEP security protocol is and how easily it can be cracked.

Material: You will need the following:

Instructions: In this tutorial I will be cracking my own WiFi router. I have set it up to WEP protocol and have a few phones connected to my network. If you will be doing this you will need to make sure that there is something connected to your network so that there is information being passed back and forth. We will be monitoring all the data and storing it to a file which we will be cracking afterwards. The more data we collect the better our success rate will be. I will also show you how to speed this process up by requesting data from the WiFi router without connecting to it. Continue Reading

How to install Kali Linux on the Raspberry Pi

About: Kali Linux is a OS that is based off of Debian. It is the successor to Backtrak and includes many tools that are used in penetration testing. Penetration testing is the act of testing a system, network or Web application to find vulnerabilities that could be exploited. The Raspberry Pi may not be the most powerful system to do penetration testing on, but it is cheap and is very easy to use. After installing Kali Linux you can set up scripts and perform attacks in the wild, and since a Raspberry Pi is very easy to hide the low cost makes it disposable.

Objective: To install Kali Linux 2.0.1 onto a Raspberry Pi B+ Model. I will be using Linux Mint to format the SD card.

Material: You will need the following:

  • Raspberry Pi
  • 8GB or larger SD card. Class 10 works best on the Raspberry Pi

Instructions: I will assume you know some basic linux terminal commands. If not this guide will be very clear regardless.

You must begin my downloading the Kali Linux Image. There is a compiled image for the Raspberry Pi located at the Offensive Security website. The download page can be found here. Scroll down half way and download the image for your Raspberry Pi. At the time of writing the current version was 2.0.1. Continue Reading
