nmap-recon
Step-by-step network reconnaissance skill for NyxStrike. Use this skill when a user asks to scan a host, discover open ports, enumerate services, or perform OS detection.
Workflow
1. Fast port discovery (rustscan or masscan)
Start with a fast sweep to identify open ports before running detailed scans.
- Prefer
rustscanfor speed on a single target. - Prefer
masscanfor large CIDR ranges.
run_tool(tool="rustscan", target="<target>", ports="1-65535")
2. Service & version detection (nmap)
Run nmap against the open ports discovered in step 1 to enumerate services, versions, and scripts.
run_tool(tool="nmap", target="<target>", ports="<open_ports>", flags="-sV -sC -O")
Useful nmap flag combinations:
| Goal | Flags |
|---|---|
| Service + version detection | -sV |
| Default NSE scripts | -sC |
| OS detection | -O |
| Aggressive (all of the above + traceroute) | -A |
| UDP scan | -sU |
| Full port range | -p- |
3. Targeted NSE scripts (optional)
If specific services are found, run targeted NSE scripts for deeper enumeration.
| Service | Suggested scripts |
|---|---|
| SMB (445) | --script smb-vuln-*,smb-enum-shares |
| HTTP (80/443) | --script http-title,http-headers,http-methods |
| FTP (21) | --script ftp-anon,ftp-bounce |
| SSH (22) | --script ssh-hostkey,ssh-auth-methods |
| SNMP (161/udp) | --script snmp-info,snmp-interfaces |
run_tool(tool="nmap_advanced", target="<target>", ports="<port>", scripts="<script_list>")
4. ARP scan (local network only)
For targets on the same subnet, use arp_scan to identify live hosts before deeper scanning.
run_tool(tool="arp_scan", target="<subnet_cidr>")
Tips
- Always confirm scope before scanning. Only scan targets you are authorized to test.
- Start with
-T3(default timing) and increase to-T4only on reliable networks. - Save output with
-oN,-oX, or-oGflags for later analysis; pass via theoutput_fileparameter where supported. - Chain results: feed open ports from rustscan/masscan directly into nmap to avoid redundant full-port scans.
