Bypassing 2FA: The Browser-in-the-Browser Attack Explained

Think the green padlock means you're safe? Think again. In this video, we demonstrate the Browser-in-the-Browser (BitB) attack—a sophisticated phishing technique that bypasses standard detection and can even intercept OTPs and 2FA sessions. I will show you how to set up a safe, isolated research lab using AWS and Docker to simulate how attackers host headless browsers to trick users. We will break down the architecture, deploy the infrastructure, and most importantly, show you how to detect and stop this attack. ⚠️ DISCLAIMER: This video is for EDUCATIONAL and SECURITY AWARENESS purposes only. The demonstration is performed in a controlled, isolated laboratory environment on my own infrastructure.
