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

A demo video below:


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

IoT-Implant-Toolkit
-------------------------------------------------------------
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
Existing plugins in our framework:
Categories Tools Descriptions Reference
Serial port debugging pyserial modem control and terminal emulation program https://github.com/pyserial/pyserial
Serial port debugging baudrate.py find correct baudrate https://github.com/devttys0/baudrate
Firmware Pack&Unpack mksquashfs create and extract Squashfs filesystem https://github.com/plougher/squashfs-tools
Firmware Pack&Unpack mkbootimg_tools Unpack&repack boot.img for Android https://github.com/xiaolu/mkbootimg_tools
Firmware Pack&Unpack cramfs make cramfs filesystem https://sourceforge.net/projects/cramfs/files/cramfs/1.1/
Firmware Pack&Unpack mountimg mount&unmount ext4 filesystems for Android system.img&data.img On our github
Software Analysis setools-android setools for Android with sepolicy-inject https://github.com/xmikos/setools-android
Software Analysis crosscomplie crosscompile toolchain for arm on our Github later
Software Analysis odex unpack Odex to smali for Android on our Github
Binary implant spy client&server a stable spy client and server, source and pre-built bins on our Github
Binary implant denoise tool denoise tool for audio porcess on our Github

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.

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.
