tumbleRF: unified fuzzing framework for low-level RF and HW protocol/PHY/MAC analysis

by do son · Published · Updated

tumbleRF

TumbleRF is a framework that orchestrates the application of fuzzing techniques to RF systems. While fuzzing has always been a powerful mechanism for fingerprinting and enumerating bugs within software systems, the application of these techniques to wireless and hardware systems has historically been nontrivial due to fragmented and siloed tools. TumbleRF aims to enable RF fuzzing by providing an API to unify these techniques across protocols, radios, and drivers.

Install

Create a Python 2.7 virtaulenv and activate it:

virtualenv -p $(which python2.7) py2-virtualenv
source py2-virtualenv/bin/activate

You should now see a prompt that looks similar to:

(py2-virtualenv) … $

Now, install the required dependencies:

git clone https://github.com/riverloopsec/tumblerf.git
pip install -r tumblerf/requirements.txt

Use

This tool needs to be scripted to carry out most tasks, however, a CLI is available for some uses.

Running ./tumblerf/cli.py will tell you what interfaces, generators, and harnesses are available so you can define each.

A very simple run case can be done based on something like the following. This just transmits random frames from one device to another which looks to see if it got them, and is thus uninteresting. However, it demonstrates how we pick the second interface to use for TX, as ReceivedFrameHarness will … TODO

(py2-virtualenv)$ zbid

           Dev Product String       Serial Number

           1:3 KILLERB001           A60400A01C25

           1:4 KILLERB001           0004251CA001



(py2-virtualenv)$ ./tumblerf/cli.py -I KillerBeeInterface -i 1:3 -G Dot15d4RandomPayloadGenerator -H ReceivedFrameHarness --rx_iface_device 1:4

 

NOTE: If you see errors such as the below, you may have a permission issue accessing your USB devices. You may correct this via your OS and permissions, or you may run with sudo (not recommended…).

ERROR:Tue Mar 13 12:16:26 2018 KillerBee Interface:Error when starting, unable to open KillerBee interface. INFO: Transmit Interface is 802.15.4 KillerBee Interface(Not Available)

## Looking at Results



You can process the JSON however you desire, but you may desire to use `parse_results.py` to visualize summaries.



## Testing



~~~bash

pytest -s

~~~



> NOTE: This will, by default, run all test suites. See notes above about certain test suites having additional dependencies.



## Contributing



We welcome bug fixes, feature additions, and more with open arms. Please submit a pull-request.



We ask that you adhere to the Python style guide and implement pytest unit testing wherever possible.
