****
Learn how attackers silently steal corporate data and how SOC teams detect them before it’s too late. In this video, we’ll break down data exfiltration step-by-step , from initial staging and covert channels (like DNS tunneling) to the forensic triage process used in real SOC environments.

What you’ll learn:
• Real-world exfiltration techniques (HTTP POST, Rclone, DNS tunnels)
• How to detect exfiltration with SIEM queries and NetFlow analysis
• The SOC playbook: triage, containment, and validation
• Red team tricks to bypass detection — and how to counter them

Based on the full TryHackMe “Data Exfiltration Detection” walkthrough and real consulting experience from government and banking environments.
