Rfcat is a sub GHz analysis tool. The goals of the project are to reduce the time for security researchers to create needed tools for analyzing unknown targets, to aid in reverse-engineering of hardware.
Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
Getting started
