Reverse Ducky is a versatile Bad USB project powered by the ATTINY85 microcontroller. It functions as a USB HID device capable of executing pre-programmed scripts or commands when plugged into a target machine. This project is inspired by USB Rubber Ducky but is designed for budget-friendly and DIY enthusiasts.
- HID Functionality: Acts as a keyboard to inject commands into a target device.
- Compact Design: Fits easily into small USB enclosures.
- Custom Scripts: Fully programmable using Arduino IDE.
- Cost-Effective: Built using the affordable ATTINY85 microcontroller.
Before you start, ensure you have the following:
- An ATTINY85 microcontroller.
- Arduino IDE installed on your computer.
- USB-to-serial adapter or similar programmer.
- DigiKeyboard library for Arduino (used for USB HID functionality).
-
Clone this repository:
git clone https://github.com/your-username/reverse-ducky.git cd reverse-ducky -
Install the required libraries in the Arduino IDE:
- DigiKeyboard library: Install via Arduino Library Manager or download here.
-
Connect your ATTINY85 to your computer using a USB-to-serial adapter.
-
Open the
reverse_ducky.inofile in Arduino IDE. -
Upload the script to the ATTINY85.
- Plug the Reverse Ducky into the target machine's USB port.
- It will execute the predefined commands or script automatically.
- To change the script, modify the
reverse_ducky.inofile and re-upload it.
Ensure that the ATTINY85 has the correct bootloader installed to enable USB functionality. Follow the bootloader tutorial below for a step-by-step guide:

- Modify the
DigiKeyboard.sendKeyStrokeandDigiKeyboard.printcommands in the script to implement your custom payload. - Use delays as necessary to ensure proper execution on the target system.
