In this post I want to talk a little about the BSides Cape Town 17 RFCat challenge and how I went about trying to build a challenge for it. Unfortunately I was not able to able to attend the con itself, but still had the privilege to contribute in some way!
The first question you may have could be: “But why RFCat?”. Truthfully, some people that are way better at this hacking thing than me (and that were also primarily responsible for this years BSides badge hardware) came up with this idea: “Wouldn’t it be cool to have a cc1111 chip on the badges?”. The cc1111 chip is RFCat compatible, so naturally this would be the goto firmware to use for the chip. With this in mind, I got invited by @elasticninja to see if I would be interested in building an RFCat based challenge and without hesitation agreed! So there we were.
