Reverse Engineering a $20 remote controlled outlet
Introduction
A few years ago, I bought a remote controlled outlet from Walmart. I don't recall the exact price, but it was less than $20. It was pretty much purchased for the explicit reason of trying to understand how they worked. The end goal, is that I wanted to know if
I could decode/intercept the signals
It was vulnerable to replay attacks

This is going to be quite a long post, so I suggest getting a cup of coffee before continuing. At the end, I have included a youtube video showing the entire process.
