Human Interface Device attacks like the USB rubber ducky are famous for being able to exploit a computer with only a few seconds of physical access by pretending to be a keyboard. In this workshop, you'll learn to program a microcontroller in Arduino to create your own scripts that run when the device is plugged into a target computer. This workshop is for beginners interested in hacking with microcontrollers, hackers interested in learning keystroke injection attacks, and anyone interested in what's possible with low-cost devices.
