📘 Definition & Purpose
Naabu is a high-speed TCP/UDP port scanner written in Go. It is designed to quickly scan thousands of hosts to locate open service ports.
🧪 Core Mechanics
Naabu utilizes raw socket parsing to perform SYN scans. It sends SYN packets to a list of target IPs/ports and listens for SYN-ACK or RST responses to identify open ports at lightning speed.
