Here’s a **YouTube video description (and optional script)** for a video titled:
🔐 **”2FA Bypass on Bitaroo | Critical Authentication Flaw | Bug Bounty POC”**
—
🎯 **In this video, I demonstrate a critical vulnerability discovered on Bitaroo where 2FA (Two-Factor Authentication) can be bypassed using a simple logic flaw in the authentication flow.**
This type of vulnerability can allow an attacker to completely take over user accounts even when 2FA is enabled — a serious issue for any platform handling sensitive data or financial transactions.
—
🧠 **What You’ll Learn:**
* What is 2FA and why it matters
* How the 2FA process on Bitaroo was flawed
* How to intercept and manipulate login flows using Burp Suite
* Real Proof-of-Concept (PoC) demo of the bypass
* Responsible disclosure and bug bounty insights
—
⚙️ **Tools Used:**
* Burp Suite
* Browser DevTools (optional)
—
📌 **Technical Steps in the POC:**
1. Log in using correct email/password
2. Intercept the request before OTP verification
3. Observe that the session token is already set (before OTP)
4. Use the session token to access the account **without entering OTP**
—
🛡️ **Impact:**
* Complete 2FA bypass
* Full user account takeover
* High-severity bug (eligible for bounty)
