Cyber Security Complete Course 2026 | From Zero to Job Ready Ethical Hacker + Blue Team Expert | The Techzeen - Cyber Security Tutorial #16: How to Gather Target Info (Recon) in Kali Linux | 2025 (Hindi/Urdu)

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. ⭐ If you found this useful — Subscribe to The Techzeen to Become a Cyber Security Expert in 2025 🔔 🔎 Reconnaissance Cheatsheet — Beginner Friendly (Kali Linux): https://github.com/farzeen-ali/Reconnaissance-for-Information-Gathering Cyber Security Concepts: https://github.com/farzeen-ali/Cyber-Security-Concepts Cyber Security Full Course 2025: https://www.youtube.com/playlist?list=PL5OhSdfH4uDuCcQ-NZ4lYa3S07FQTFtrY DevOps Tutorial 2025: https://www.youtube.com/playlist?list=PL5OhSdfH4uDsyUM02ZHl2mOYBpihCYsml React Native Full Course 2024 : https://www.youtube.com/playlist?list=PL5OhSdfH4uDuUpj3fwknoUVBkT2oMXyOl Cyber Security Full Course 2025 Beginner To Advanced (Hindi/Urdu) Ethical Hacking Full Course The Techzeen 2025 #CyberSecurityTutorial #Reconnaissance #OSINT #KaliLinux #Nmap #Subfinder #theHarvester #WebRecon #InformationGathering #EthicalHacking #CyberSecurityForBeginners #Pentesting #RedHawk #TheTechzeen #CyberSecurity2025 #CyberSecurityFullCourse #EthicalHackingFullCourse
