Quick Reference

Common Port Scans

# Quick scan
nmap -F 192.168.1.1

# Full comprehensive
nmap -sV -sC -A -p- 192.168.1.1

# Fast with version
nmap -sV -T4 192.168.1.1

Password Hash Types

Constraints

• Always have written authorization
• Some scans are noisy and detectable
• Brute forcing may lock accounts
• Rate limiting affects tools

Examples

Example 1: Quick Vulnerability Scan

nmap -sV --script vuln 192.168.1.1

Example 2: Web App Test

nikto -h http://target && sqlmap -u "http://target/page?id=1" --dbs
