Sending AM-OOK using Metasploit and rftransceiver

Introduction 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. How things fit together First things first. I had to try and understand how this new functionality actually works. From the Metasploit blog post, it was possible to see that the additions allowed you to communicate with a RFCat capable device from Metasploit and run modules over a session. A session is started by connecting to a small JSON API (with a python helper) that bridges HTTP requests to rflib methods.
