      Bypassing client-side validation

  6. Using Burp Suite for Bug Bounty
  
      How hunters use Burp to:
  
          Find IDORs
  
          Check for insecure direct object references
  
          Chain exploits using Repeater + Intruder
  
      Add extensions like:
  
          Active Scan++
  
          Turbo Intruder
  
          Autorize (for auth testing)

  7. Recommended Extensions (BApp Store)
  
      JS Beautifier – Beautify minified JavaScript
  
      Retire.js – Find vulnerable JavaScript libraries
  
      Param Miner – Discover hidden/unused parameters
  
      Backslash Powered Scanner – Detect edge case injection flaws
  
  8. Tips and Best Practices
  
      Always target authorized apps — never test without permission.
  
      Use scope restriction to limit where your scans/intercepts run.
