A Step-by-Step Guide to Uncovering IDOR Flaws in Mobile Apps (With Real Proof!)

Introduction: When Curiosity Pays Off 💸

Most people use their smartphones for social media, shopping, or streaming. I decided to hack mine.
As a budding ethical hacker, I turned my Android device into a testing lab — and discovered two Insecure Direct Object Reference (IDOR) vulnerabilities in a popular social media app. The result? A $1,500 bounty and a lesson in real-world cybersecurity. Here’s how you can do it too.

What Is IDOR? 🤔

IDOR (Insecure Direct Object Reference) is a vulnerability that lets attackers bypass authorization and access restricted data by manipulating URLs, APIs, or input parameters. Think of it as walking into a bank vault because the lock didn’t check your ID.

Example:
If a URL like https://app.com/profile?user_id=123 lets you view any profile by changing the user_id (without permission checks), that’s IDOR.
