About:
Smap is a command-line utility that leverages Shodan's internet-wide scan data to perform network discovery and reconnaissance. It serves as a direct drop-in replacement for Nmap, accepting the same command-line arguments and output formats. This allows security professionals to conduct port scans on a massive scale without sending a single packet to the target network.
Key Features:
  • Drop-in replacement for Nmap with identical syntax
  • Uses Shodan data for passive reconnaissance
  • No network packets sent to targets
  • Bypasses firewall rules and intrusion detection
Use Cases:
  • Passive network reconnaissance and asset discovery
  • Penetration testing reconnaissance phase
  • Identifying exposed services without triggering alerts
Alternatives:
  • Nmap – Active scanning tool that sends packets; Smap is passive and uses external data
  • Masscan – High-speed active scanner; Smap requires no network traffic
