BullDog

Python USB OTG HID (Keyboard) for Raspberry PI Zero (and other)

Inspired by RubberDucky, O.MG cable and other nice tools (e.g. Cactus WHID, BadUSB), I created this Python3 BullDog cli tool. As I was a little unhappy with the DuckyScript and WHID syntax, I developed the new Barking syntax (which is very similar).

Preparation

If you need to create a USB OTG HID, here you will find all information (for Raspberry PI Zero).

# install git and pip (Python 3.x)
$ sudo apt install git python3-pip

Usage

# clone repository
$ git clone https://github.com/Lupin3000/BullDog.git

# change into cloned directory
$ cd BullDog/

# install via pip3 (system wide or virtualenv) 
$ pip3 install .

# show help (optional)
$ bulldog -h

# execute barking script
$ bulldog -b examples/macOS/woof.txt

# execute barking script with default delay
$ bulldog -b examples/macOS/woof.txt -d 0.05

# just test barking script (no need for /dev/hidg0)
$ bulldog -b examples/macOS/woof.txt -t

# write some string directly
$ bulldog --text "who am i" -t

# write some command directly
$ bulldog --command "GUI SPACE" -t

Note: -b|--barking, --text and --command cannot be used together!

The Barking script

Example of the barking script woof.txt (simple text file)...

# This is a simple barking script example for macOS
