I built my own USB Rubber Ducky using a $15 Raspberry Pi Zero and in this video, I show exactly how hackers use devices like this in real HID attacks. A USB Rubber Ducky is a tiny device that pretends to be a keyboard. Because computers trust keyboards by default, these devices are very dangerous. In this video, I break down how Rubber Duckies work, how I built my Ducky Pi, and why HID-based attacks are something every defender should understand. I also show 3 real demos (with the typing slowed in the script so you can actually see what’s happening). The real payload fires almost instantly. If you're learning cybersecurity, ethical hacking, red teaming, or you love Raspberry Pi projects, this is a great intro to physical access attacks, HID payloads, and how to protect your environment. ⏱️ Timestamps 0:00 – The innocent-looking Pi that can take over a PC 0:25 – What a Rubber Ducky really is & How HID attacks work 1:35 – Demo #1 (Notepad payload) 1:49 – Demo #2 (PowerShell payload) 2:03 – Demo #3 (Fun payload) 2:19 – Lessons learned & Hypothetical 3:05 – Why defenders MUST understand HID attacks 3:23 – How to build your own Ducky Pi 🔗 Build It Yourself (GitHub): LINK IN COMMENT ⚠️ Ethical Reminder Only use devices like this on systems you own or have explicit permission to test.
