Decoding RF Protocols Within GRC
I’ve been fascinated by SDR and everything you can do with it for a long time, and from a pentesters perspective, I thought it would be awesome to be able to fuzz random devices. RF devices are everywhere, and people have used SDR to mess with lots of devices, such as portable traffic lights, weather stations, and older car key fobs. The thing is, getting started is much harder than…
building the bsidescpt17 rfchallenge
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…
Sending AM-OOK using Metasploit and rftransceiver
Towards the end of last year, I found myself playing around with some basic amplitude modulation (AM)/On-off keying (OOK) software defined radio. That resulted in ooktools being built to help with making some of that work easier and to help me learn. A little while ago, the Metasploit project announced new ‘rftransceiver’ capabilities that were added to the framework with a similar goal of making this research easier. First things…
