Nmap Post Port Scans

medium2htryhackme

Port numbers tell you where to knock. Version detection tells you what answered. OS fingerprinting tells you who built the house. NSE scripts are your automated recon army — finding robots.txt, checking for CVEs, querying DNS BIND versions, and enumerating SSH host keys without leaving your Nmap command. This is the final room in the Nmap series: taking a list of open ports and converting it into actionable intelligence about services, versions, OS, and known vulnerabilities. Everything you need to write findings and decide what to exploit next.
