Bit of a beginner question here but I am interested in getting into wifi password cracking (not for illegal means just as a skill to have in my back pocket). How would I go about creating something like a raspberry pi password cracking box that runs kali???
Thanks for the help!
I tried this to without much luck. Don't download the Kali distro specifically for raspberry pi because it does not come with any of the hacking software that normal Kali comes with, and it didn't handle downloading the software very well. it might have been by very small sd card. I would recommend finding an extremely light distro, and downloading metaspoit and other such tool, but you will need a larger sd card.
While you could probably do the packet capture portion with a Raspberry Pi, It doesn't have enough horsepower to do the brute-force cracking at any decent speed. If you capture the handshake packet with the Pi, you could later transfer the file to a beefier machine to do the heavy lifting part. That is what I would suggest if you really wanted to use the Pi for WiFi cracking.
I have played around with Kali off and on for sometime, and you have a few routes I would recommend. First, a better system than a raspberry pi (i.e. something with multiple cores) or you could use a virtual machine on a beefier machine (if you don't want to wipe out your existing OS setup). This is the route I went and I use VMPlayer for my Kali Linux VM as I have found the USB Passthrough for accessing my Alpha. Works great!
I also like to play with non-wifi exploits and have Metasploitable2 installed on a VirtualBox VM, a WindowsXP VirtualBox VM and Kali Linux VirtualBox VM on their own inet (internal network to avoid impacting my main or other computers on my homenetwork). A fun easy setup to play around with...
What are you using for the WiFi packet capture device? An alpha? What is your test exploit setup like?
If you are thinking WPS cracking, Rasberry is good anough and handshake stealing. i normally just use and Encrypted Persisten USB3 drive for Kali, it works like a charm, i can update it and save captures, scripts.
There are actually Raspberry PI 2 images on the Offensive Security download page now. The Pi 2 would be a better shot but it will still take you decades to get through anything serious. Just for learning purposes though, it should be alright. Probably easier to grab the ISO and make a VM that has more power than the Pi... Costs less too!
If you do want to crack on your raspberry pi for learning purposes just install raspian and then install the aircrack-ng software suite "sudo apt-get install aircrack-ng".
Yeah, I have to agree with biodrone, with the Pi 2 along with the images itself is a good tool for beginners as well. A VM would be much cheaper on you with the added benefit of more power to boot.
