Hardware Hacking: Plunder With a Bus Pirate

This blog-style guide explains step-by-step how to find UART pins on an embedded device, use a multimeter to identify ground and power pins, connect a Bus Pirate to the UART TX/RX lines, configure serial parameters, obtain a root shell, and locate credentials stored in nvram. It is an instructional piece focused on hardware debugging and device access rather than a report of an actual security incident.
