Nmap

Naabu is a modern port scanner built by the ProjectDiscovery team. Written in Go, it focuses on high performance, ease of integration, and usage in engineering pipelines. If Nmap is the classic all-rounder and Masscan is the representative of extreme speed, then Naabu is the “modern, automated, orchestratable” intermediate state between the two. 🚀 Tool Positioning Naabu implements port scanning via SYN/CONNECT/UDP probing methods, supporting: DNS resolution and automatic deduplication IPv4 / IPv6 mixed scanning (experimental) Passive port enumeration (Shodan / InternetDB) Host discovery and Nmap integration Multiple inputs (Domain / IP / CIDR / ASN) and multiple output formats (JSON / TXT / STDOUT) ⚙️ Key Technologies and Implementation in Naabu 1️⃣ Concurrency Model: Goroutine + Worker Pool Naabu uses Go’s native goroutine and channel model to drive large-scale scanning tasks. Each probe task is assigned to a worker pool for asynchronous execution, realizing the flow of “Massive Tasks → Lightweight Threads → Aggregated Output”. ...

Most people who know about network scanners should have heard the name Nmap. If we were to select the most excellent scanning tool, or the top hacker weapon, Nmap would definitely be on the list. Nmap is a free, open-source scanning tool with excellent network asset scanning capabilities. In addition to common port scanning, Nmap also supports operating system detection and service identification. Through its built-in probes and fingerprint library, it can accurately identify the fingerprints of most operating systems and application services. ...
