Exploitation Primitives

TechniqueTool / CommandResult
Reconnmap -sV -sC -p- <target>Full port/service scan
Enumerationnmap --script <service>-* -p <port> <target>Service-specific NSE scripts

Notes

Always start with full port scan: `nmap -sV -sC -p- <target>`.

Check for default credentials before brute-forcing.

Use service-specific NSE scripts: `nmap --script <service>-* -p <port> <target>`.

Remember to check both IPv4 and IPv6 if applicable.
