IoT-Implant-Toolkit

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 succcessfully implanted Trojans in eight devices including smart speakers, cameras, driving recorders and mobile translators with IoT-Implant-Toolkit.

How to use

Installation

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 https://github.com/arthastang/IoT-Implant-Toolkit.git

Set up environment and install dependencies:

$ cd IoT-Implant-Toolkit/
$ python3 setup.py install

Run

Run the toolkit:

$ python3 -B IoT-Implant-Toolkit.py

            -------------------------------------------------------------
                      A Framework for IoT implantation research.

                                   by Marvel Team

            Command:
            list - List all tools
            run - Run a specific tool
            exit - Exit

                
[Implant-Toolkit]>

Three commands supported：
list: list all plugins
run: run a specific plugin with "run [plugin] [parameters]"
exit: exit

Features

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:

--IoT-Implant_toolkit.py         #Startup script
--outputs/                       #Default folder of outputs
--toolkit/                       
  |---core/                      
      |---basic/                 #Basic plugin class defination
      |---cli/                   #Shell-like cli defination
      |---toollist/              #Auto updating toollist of plugins 
  |---plugins/                   
      |---firmware/              #Plugins for firmware modification
      |---implant/               #Plugins for generate spy programs
      |---serialport/            #Plugins for serial port debugging
      |---software/              #Plugins for software analysis especially for Android
  |---tools/                     #Other tools

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.
