Testing a postMessage Finding on a Real Target

In this video, I’m testing a postMessage finding on a real bug bounty target.

The goal was to figure out whether the behavior was actually exploitable or just an interesting-looking finding that falls apart under validation. I used Claude to help reason through the code, check the message flow, and validate whether the missing origin check created a real security impact.

This is what bug bounty hunting actually looks like sometimes: not every finding becomes a report, but every proper investigation makes your process sharper.
