WaveConverter: An Open Source RF Reverse Engineering Tool

During the Schmoocon 2017 conference presenter Paul Clark introduced a new open source Linux tool called WaveConverter which he’s been working on for reverse engineering RF signals. Paul writes:

WaveConverter is a tool that helps you extract digital data from RF transmissions that have been captured via Software Defined Radio (SDR). After the user defines the modulation parameters, framing and encoding, WaveConverter will process a stored I-Q file and extract the data from any transmissions that match this definition. Using programmable timing tolerances and glitch filters, WaveConverter is able to extract data from signals that would otherwise appear corrupted.

This software will make the process of reverse engineering signals easier and more error-proof. Because WaveConverter includes the ability to store and retrieve signal protocols (modulation + encoding parameters), we have been generating a database of protocols that we can quickly use to iteratively attack unknown signals.

This tool should be very useful for reverse engineering digital signals, such as those found in keyfobs, wireless doorbells, wireless temperature sensors and any other simple RF device. Simply use an SDR device like an RTL-SDR to capture a sample of the signal of interest and then open it up in WaveConverter to first easily analyze the signal and determine it’s properties, then to automatically demodulate any subsequent signal into a binary string. For more information the documentation can be found here (pdf).

WaveConverter seems to be quite similar in purpose to Inspectrum and DSpectrum which are two Linux tools that are also designed for reverse engineering digital signals.
