🎯 Overview

NullSec UART automates the discovery and exploitation of serial debug consoles on embedded devices. Hidden UART interfaces are one of the most common hardware attack surfaces — often providing root shells, bootloader access, and firmware update capabilities.

⚡ Features

Feature	Description
Baud Detector	Auto-detect baud rate from 300 to 4M baud
Pin Finder	Identify TX/RX pins using signal analysis
Console Logger	Record serial output with timestamps
Command Injector	Automated command injection via serial
Bootloader Detector	Identify U-Boot, Barebox, CFE, and custom bootloaders
Shell Detector	Detect root shells, BusyBox, and restricted environments
Firmware Extractor	Dump firmware via bootloader commands (XMODEM, YMODEM)
