urh - Universal Radio Hacker: Investigate Wireless Protocols Like A Boss

•    Python

The Universal Radio Hacker (URH) is a complete suite for wireless protocol investigation with native support for many common Software Defined Radios. URH allows easy demodulation of signals combined with an automatic detection of modulation parameters making it a breeze to identify the bits and bytes that fly over the air. As data often gets encoded before transmission, URH offers customizable decodings to crack even sophisticated encodings like CC1101 data whitening. When it comes to protocol reverse-engineering, URH is helpful in two ways. You can either manually assign protocol fields and message types or let URH automatically infer protocol fields with a rule-based intelligence. Finally, URH entails a fuzzing component aimed at stateless protocols and a simulation environment for stateful attacks. We encourage researchers working with URH to cite this WOOT'18 paper or directly use the following BibTeX entry.

Salamandra - Salamandra is a tool to find spy microphones that use radio freq to transmit

•    Python

Salamandra is a tool to detect and locate spy microphones in closed environments. It find microphones based on the strength of the signal sent by the microphone and the amount of noise and overlapped frequencies. Based on the generated noise it can estimate how close or far away you are from the microphone. To use Salamandra you nee to have a SDR (Software Define Radio) device. It can be any from the cheap USB devices, such as this.

luaradio - A lightweight, embeddable software-defined radio framework built on LuaJIT

•    Lua

LuaRadio is a lightweight, embeddable flow graph signal processing framework for software-defined radio. It provides a suite of source, sink, and processing blocks, with a simple API for defining flow graphs, running flow graphs, creating blocks, and creating data types. LuaRadio is built on LuaJIT, has a small binary footprint of under 750 KB (including LuaJIT), has no external hard dependencies, and is MIT licensed. LuaRadio can be used to rapidly prototype software radios, modulation/demodulation utilities, and signal processing experiments. It can also be embedded into existing radio applications to serve as a user scriptable engine for processing samples.

gr-ieee802-11 - IEEE 802.11 a/g/p Transceiver

•    C++

This an IEEE 802.11 a/g/p transceiver for GNU Radio that is fitted for operation with Ettus N210s and B210s. Interoperability was tested with many off-the-shelf WiFi cards and IEEE 802.11p prototypes. The code can also be used in simulations. Like GNU Radio, this module uses master and next branches for development, which are supposed to be used with the corresponding GNU Radio branches. I recommend staying up-to-date by using the next branch.

trunk-recorder - Records calls from a Trunked Radio System (P25 & SmartNet)

•    C++

Trunk Recorder is able to record the calls on trunked and conventional radio systems. It uses 1 or more Software Defined Radios (SDRs) to do this. The SDRs capture large swatches of RF and then use software to process what was received. GNURadio is used to do this processing because it provides lots of convenient RF blocks that can be pieced together to allow for complex RF processing. The libraries from the amazing OP25 project are used for a lot of the P25 functionality. Multiple radio systems can be recorded at the same time. Trunk Recorder has been tested on Ubuntu (14.04, 16.04, 16.10, 17.04, 17.10 & 18.04), Arch Linux (2017.03.01), Debian 9.x and macOS (10.10, 10.11, 10.12, 10.13, 10.14). It has been successfully used with several SDRs including the Ettus USRP B200, B210, B205, a bank of 3 RTL-SDR dongles, and the HackRF Jawbreaker.

node-adsb - An ADS-B decoder in node

•    Javascript

This is an ADS-B decoder in node. When partnered with some source of ADS-B data, it will decode packets and... DO THINGS. You will need a signal source. A good source is either rtl-sdr or dump1090, if you have the hardware to receive live signals. Otherwise, it will be possible to either listen to an ADS-B aggregator or local files.
