I made this to compete with the expensive Pwnie Express stuff and to be more robust than WiFi Pineapple
I also made it to save time and automate the tedious setup for MITM attacks.
While the software exists to do all this stuff, it's not all in one place and it's not pre-formatted. It was taking me forever to set up all the little things that you need to make something like this work correctly and work stably.
While it is a collection of pre-written software, I did take the time to fix, compile, correctly configure, automate, and install all of the software packages to work together. Then I did it so it would work on the Raspberry Pi, and then I wrote some more software and tools when things didn't exist or work.
It's more than a random assortment of tools, it's meant to save you, me, and the next guy time and money.
