Stuck In "tutorial Hell": I Know The Theory Of Idor Perfectly, But Can't Find Anything In The Wild. How Do I Bridge The Gap?

Hey everyone,

I’m currently facing a huge roadblock in my bug bounty journey and could really use some practical advice from the hunters here.

I recently managed to score my very first bounty by finding a simple Open Redirect. That gave me a massive motivation boost, so I decided to dive deep into higher-impact vulnerabilities, specifically IDOR and Business Logic flaws.

I feel like I’ve done my homework. Here is what I’ve studied so far:

Solved all the relevant PortSwigger Web Security Academy labs.

Read the related chapters in Peter Yaworski's "Real-World Bug Bounty Hunting".

Read countless write-ups on Medium.

Watched hours of YouTube tutorials and PoCs.

I understand the mechanics of IDOR perfectly in theory. The problem? The moment I jump onto a real-world target, I freeze.

The applications are massive, the APIs are complex, and the endpoints don't look anything like the clean, obvious ?user_id=1 parameters I saw in the labs. I end up staring at my Burp Suite HTTP history, testing random GUIDs, and ultimately finding absolutely nothing. It feels like there is a massive gap between the sterilized environments of CTFs/Labs and the messy reality of production apps.

My questions for you:

How did you personally bridge the gap between understanding a vulnerability in a lab and actually spotting it in the wild?

What is your practical methodology when hunting for IDORs on a fresh target? (Where do you look first? How do you map the app?)

Are there specific features or target types you recommend for someone transitioning from theory to practical hunting?

Any advice, methodology tips, or reality checks would be massively appreciated. Thanks in advance!
