If you're interested in what you can do with this (without being there to observe the screen), here is a list of payloads written by others:

https://github.com/hak5darren/USB-Rubber-Ducky/wiki/Payloads

A while ago I wrote a Rubber Ducky server [1] that is remote controlled and uses a Raspberry Pi Zero W (which supports being a USB HID device).

Once connected to a host computer, it exposes a hidden WiFi network that allows you to inject and run Ducky Scripts remotely in real time using a small web interface.

It also includes a Ducky Script parser written in Python which could be useful outside of this project. You can grab it here [2]

I wrote something similar to this, except it used the caps lock key to get data back across from the computer. The benefit is that you don't need to rely on a network to get data back. Often the keyboard is the most trusted device on the machine.

Glad this is a thing - having lost 2 rubber duckies myself, a cheaper alternative is great. Only thing I would need is DuckyScript compatibility, so I wouldn't need to rewrite all my existing payloads.

Fortunately, tools already exist to translate regular ducky scripts to digispark:

By the way, the repo author has done a lot of work to develop a whole USB attack platform based on Raspberry Pi 0, which really deserve some interests:

When you say you lost them, do you mean you 'accidentally' lost them in a company parking lot?!?

It doesn't look too hard to re-write existing payloads, but you need to do some translation from, e.g.

Rubber ducky:

  GUI r

This project:

  DigiKeyboard.sendKeyStroke(KEY_R, MOD_GUI_LEFT);

Awesome. Does anyone know of a USB-C alternative?

I've spun a few Digispark based designs, and you can basically just replace the micro-usb connector with a usb-c one.
