Offensive IoT for Red Team Implants (Part 2)

This blog provides a step-by-step guide to building an offensive IoT implant using a Raspberry Pi Pico (Pico W) programmed with CircuitPython to emulate a USB keyboard (Rubber Ducky) and to receive DuckyScript payloads over LoRa. It covers installing CircuitPython and required libraries, writing implant and sender firmware, enabling filesystem writes, and a host-side sender script to transmit payloads line-by-line; the result is an implant that executes keystroke-injection payloads locally and can be updated remotely via LoRa.
