Hacking with Raspberry Pico: Terminal Text Injection and File Stealing
This article on DEV Community details how to use a Raspberry Pico microcontroller as a physical hacking device for terminal text injection and file stealing. The Pico, running CircuitPython v9.1.4 and the pico-ducky library (commit #22), acts as a USB HID device to inject keystrokes into a host system. The exploits are written in DuckyScript, a language interpreted by pico-ducky. The article covers practical attacks such as opening a text editor and writing a message, as well as more advanced file exfiltration techniques. It explicitly states that the content is for educational purposes only and advises using only owned devices. The Pico's small form factor and full USB stack access make it suitable for such hacking projects. The article builds on a previous guide about USB HID device programming and provides a concise introduction to DuckyScript.
Developers can understand USB HID attack vectors and how microcontrollers enable physical exploits.
