🎯 Fuzzing

Wordlists find what the application never linked. Build the list from the target, not only from SecLists.

How recon & tooling actually works — taught by The XSS Rat

What it is

Most people fail at bug bounty before they test anything, because they look at the same five pages as everyone else. Recon is how you end up on an endpoint nobody has read yet - the JS bundle, the forgotten subdomain, the parameter that is not in the UI.

How I attack it

  1. Read the JavaScript. Routes, API versions, feature flags and keys are compiled into it.
  2. Fuzz with a wordlist built from the target, not only from SecLists. The app tells you its own vocabulary.
  3. Keep notes per target. The second session should start where the first one stopped, not at the homepage.
  4. Automate what is boring, then spend the time you saved on the logic nobody automated.
