Smap
AGPL-3.0🌐 Network Recon · Go
Smap is a passive port scanner that replicates Nmap's interface and output format while using Shodan's internet-wide scan data instead of actively probing targets. It accepts the same command-line arguments as Nmap, making it a drop-in replacement for reconnaissance scenarios where stealth is critical. Since Smap queries Shodan's existing database rather than sending packets to targets, it leaves zero network footprint on the target infrastructure. Results include open ports, service banners, and version information that Shodan has previously collected.
Installation
$ go install github.com/s0md3v/smap@latestUse Cases
- Stealthy port scanning without touching the target
- Quick reconnaissance using existing Shodan data
- Drop-in Nmap replacement for passive workflows
- Pre-engagement intel gathering without triggering IDS
