The Universal Radio Hacker is a software for investigating unknown wireless protocols

Features include

• hardware interfaces for common Software Defined Radios
• easy demodulation of signals
• assigning participants to keep overview of your data
• customizable decodings to crack even sophisticated encodings like CC1101 data whitening
• assign labels to reveal the logic of the protocol
• fuzzing component to find security leaks
• modulation support to inject the data back into the system

Check out the wiki for more information and supported devices.

Installation

Universal Radio Hacker can be installed via pip or using the packet manager of your distribution (if included). Furthermore, you can install urh from source or run it without installation directly from source.

Dependencies

• Python 3.4+
• numpy / psutil / zmq
• PyQt5
• C++ Compiler

Optional

• librtlsdr (for native RTL-SDR device backend)
• libhackrf (for native HackRF device backend)
• libairspy (for native AirSPy device backend)
• liblimesdr (for native LimeSDR device backend)
• libuhd (for native USRP device backend)
• rfcat (for RfCat plugin to send e.g. with YardStick One)
• gnuradio / gnuradio-osmosdr (for GNU Radio device backends)

Installation examples

Arch Linux

yaourt -S urh

Ubuntu/Debian

If you want to use native device backends, make sure you install the -dev package for your desired SDRs, that is:

• AirSpy: libairspy-dev
• HackRF: libhackrf-dev
• RTL-SDR: librtlsdr-dev
• USRP: libuhd-dev

If your device does not have a -dev package, e.g. LimeSDR, you need to manually create a symlink to the .so, like this:

sudo ln -s /usr/lib/x86_64-linux-gnu/libLimeSuite.so.17.02.2 /usr/lib/x86_64-linux-gnu/libLimeSuite.so

before installing URH, using:

sudo apt-get update
sudo apt-get install python3-numpy python3-psutil python3-zmq python3-pyqt5 g++ libpython3-dev python3-pip
sudo pip3 install urh

Gentoo/Pentoo

emerge -av urh

Windows

If you run a Python 3.4 you need to install Visual C++ Build Tools 2015 first. It is recommended to use Python 3.5 or later on Windows, so no C++ compiler needs to be installed.

1. Install Python 3 for Windows.

• Make sure you tick the Add Python to PATH checkbox on first page in Python installer.
• Choose a 64 Bit Python version for native device support.

2. In a terminal, type: pip install urh.
3. Type urh in a terminal or search for urh in search bar to start the application.

Mac OS X

1. Install Python 3 for Mac OS X. If you experience issues with preinstalled Python, make sure you update to a recent version using the given link.
2. (Optional) Install desired native libs e.g. brew install librtlsdr for corresponding native device support.
3. In a terminal, type: pip3 install urh.
4. Type urh in a terminal to get it started.

Update your installation

If you installed URH via pip you can keep it up to date with

pip3 install --upgrade urh

If this shouldn’t work you can try:

python3 -m pip install --upgrade urh

Running from source

If you like to live on bleeding edge, you can run URH from source.

Without installation

To execute the Universal Radio Hacker without installation, just run:

git clone https://github.com/jopohl/urh/
cd urh/src/urh
./main.py

Note, before first usage the C++ extensions will be built.

Installing from source

To install from source you need to have python-setuptools installed. You can get it e.g. with pip install setuptools. Once the setuptools are installed use:

git clone https://github.com/jopohl/urh/
cd urh
python setup.py install

And start the application by typing urh in a terminal.
