Purpose: Naabu is a Go port-scanning tool that enumerates valid ports on hosts using SYN, CONNECT, and UDP scans.
Scanning: It supports fast SYN, CONNECT, and UDP probe-based scanning.
Inputs: It accepts STDIN, hosts, IPs, CIDRs, and ASNs as scan inputs.
Outputs: It supports JSON, TXT, and standard-output formats.
IPv4 and IPv6: IPv4 and IPv6 port scanning is supported, with IPv6 marked experimental in the feature list.
Passive enumeration: Passive port enumeration can use Shodan InternetDB.
Host discovery: Host discovery scanning is available and marked experimental.
Nmap integration: Naabu integrates with Nmap for service discovery and additional scans.
Cloud dashboard: The CLI can upload or display scan output in the ProjectDiscovery Cloud dashboard and can associate results with team and asset IDs.
CDN and WAF exclusion: CDN/WAF exclusion can limit scans to ports 80 and 443 for supported Cloudflare, Akamai, Incapsula, and Sucuri IPs.
Installation: The maker provides ready-to-run binaries, Docker installation, and Go installation.
Platform prerequisites: Packet capture requires libpcap on Linux and macOS or Npcap on Windows.
Operational requirement: The README recommends running Naabu as root for best results and tuning flags and scan rate on local systems.
Pipeline integration: Discovered ports can be piped to httpx to identify running HTTP servers.
