How Hackers Utilize Nmap Techniques

How Hackers Use Nmap 1. Finding Targets ("Who’s Home?")

Command: nmap -sn 192.168.1.0/24 What it does: Pings every device on a network (like

shouting "HELLO?" and seeing who answers). 2. Checking Doors ("Which Ports Are Open?")

Command: nmap -p 80,443,22 10.0.0.1 What it does: Checks if Port 80 (Web), 443 (HTTPS),

or 22 (SSH) are open (like jiggling doorknobs). 3. Spying on Guards

("What’s Running?") Command: nmap -sV 10.0.0.1 What it does: Detects if the target is

running Apache, Windows, or old software (like reading name tags on guards).

4. Finding Weak Doors ("Can I Break In?") Command: nmap --script vuln 10.0.0.1
