Want to learn how hackers and security pros collect target info?
In Cyber Security Tutorial, I show practical Reconnaissance (Recon) techniques in Kali Linux — step-by-step, hands-on, and beginner friendly. Learn how to gather domains, subdomains, IPs, services and public intel using real tools and real commands.

What you’ll learn (practical + theoretical):
Recon basics: Passive vs Active Recon & when to use each
Quick legal reminder: Only scan systems you own or have permission to test
Essential tools & commands I used in Kali Linux:
* ping -c 4 scanme.nmap.org (connectivity)
* traceroute scanme.nmap.org (network hops)
* whois example.com (domain metadata)
* dig example.com A +short (DNS lookup)
* theHarvester -d example.com -b bing (OSINT)
* subfinder -d example.com -silent subs.txt (subdomains)
* curl -s "https://crt.sh/?q=%25.example.com&output=json" | jq '.[].name_value' | sort -u (crt.sh cert search)
* sudo nmap -sS -p 1-1000 -T4 scanme.nmap.org (SYN port scan)
* curl -I http://example.com (HTTP headers)
* Red Hawk one-shot web recon

Why this matters:
Recon builds the attack surface — knowing how to collect & validate data is the foundation of every pentest, bug bounty, and defensive audit.

Practice safely:
Use scanme.nmap.org, your lab VMs, or TryHackMe/HackTheBox labs. Do NOT scan targets without explicit permission.
