IoT Implant : Toolkit For Implant Attack Of IoT Devices

IoT Implant Toolkit is a framework of useful tools for malware implantation research of IoT devices. It is a toolkit consisted of essential software tools on firmware modification, serial port debugging, software analysis and stable spy clients.

With an easy-to-use and extensible shell-like environment, IoT-Implant-Toolkit is a one-stop-shop toolkit simplifies complex procedure of IoT malware implantation.

In our research, we have successfully implanted Trojans in eight devices including smart speakers, cameras, driving recorders and mobile translators with IoT-Implant-Toolkit.

How to use?


Make sure you have git, python3 and setuptools installed.
For audio processing and playing, you should install alsa(built-in in linux), sox and ffplay. On ubuntu18.04:

$ sudo apt install sox ffmpeg

Download source code from our Github:

$ git clone

Set up environment and install dependencies:

$ cd IoT-Implant-Toolkit/
$ python3 install


Run the toolkit:

$ python3 -B
list – List all tools
run – Run a specific tool
exit – Exit

Three commands supported´╝Ü
list: list all plugins
run: run a specific plugin with “run [plugin] [parameters]”
exit: exit


Each software tool acts as a plugin which can be easily added into the framework.

There are more than ten plugins in four categories, including topics on serial port debugging, firmware pack&unpack, software analysis, and implanted spy programs.

List of Plugins

Create new plugins

Code structure:

Create [newplugin].py in corresponding folder(category) and define init attributes to add a new plugin to IoT-Implant-Toolkit.The framework will detect new plugin automatically when startup.

Other useful software tools

We have not added more plugins due to time limitation.

Chart below are tools not fits our framework, but may be useful.

We hope that IoT-Implant-Tookit will be an essential toolkit in malware implantation.
