If you understand the protocols that interact directly with a system’s electronic components, you can target IoT devices at the physical level. The Universal Asynchronous Receiver-Transmitter (UART) is one of the simplest serial protocols, and its exploitation provides one of the easiest ways to gain access to IoT devices. Vendors typically use it for debugging, which means that you can often obtain root access through it. To accomplish this, you’ll need some specialized hardware tools; for instance, it’s common for attackers to identify the UART pins on a device’s printed circuit board (PCB) using a multimeter ...
