Rubber Ducky

Hola, he estado pensando en comprar o hacer un USB Rubber Ducky para hacerle una broma a un amigo (es inofensiva y muy simple), pero no creo que vaya a gastarme 80 euros en uno de primera calidad, ¿alguien me puede ayudar?

Muchas gracias y lo siento si este es el subreddit equivocado.

Could use any of those mini rp2040 boards.

A rubber ducky is very simple. Its just a microcontroller with usb functionality builtin that runs a special software that makes it able to emulate the signals a keyboard would send. Its very easy and there are pre-existing projects that allow you to do so.

Rp2040 is popular as its exactly that. A microcontroller with builtin USB. Its commonly found on raspberry pi pico and other small boards. You just need to put software on it for which there exist many projects around. If you want wifi functionality and remote control functions you need a rp2040 board or raspberry pi pico with wireless chip onboard.

I’m not going into the technical side of Rubber Ducky payloads because “harmless prank” is doing a lot of work here.

A normal USB can carry malicious files, but a Rubber Ducky is different because it acts like a keyboard and fires commands into the machine. On someone else’s computer, that stops being a prank pretty quickly.

You probably don’t need one anyway. Learn PowerShell, Bash, and basic scripting on your own machine. That’ll teach you more than trying to be USB prank man for 80 euros.
