About Course

Bug bounty hunting is the art and science of finding security vulnerabilities in real-world applications and getting paid for responsible disclosure. This course takes you from zero knowledge to a fully equipped hunter ready to submit valid reports on HackerOne, Bugcrowd, Intigriti, and private programs.

You will learn reconnaissance, every major web vulnerability class, API hacking, mobile testing fundamentals, and — critically — how to write professional reports that get triaged and paid quickly.

What Will You Learn?

  • Conduct professional reconnaissance on any target in scope
  • Discover and exploit XSS, SQLi, SSRF, IDOR, XXE, SSTI, and more
  • Test REST APIs, GraphQL, and WebSocket endpoints
  • Chain vulnerabilities for maximum impact and bounty value
  • Write clear, reproducible vulnerability reports that get paid
  • Manage your pipeline across multiple programs simultaneously
  • Build a personal recon automation toolkit

Course Content

MODULE 01: The Bug Bounty Ecosystem
Before writing a single payload, you need to understand the landscape: how programs work, what gets paid, legal boundaries, and how to think like a professional hunter.

  • 1.1 What is Bug Bounty Hunting?
  • 1.2 Platforms & Program Types
  • HackerOne : Largest platform, government programs
  • Bugcrowd : VDP & private programs
  • Intigriti : European focus, high bounties
  • Synack : Invite-only, vetted researchers
  • YesWeHack : European & global programs
  • 1.3 Reading a Program Policy
  • Scope: in-scope domains, IP ranges, mobile apps — TEST ONLY THESE
  • Out-of-scope: third-party services, DoS attacks, physical attacks, social engineering
  • Severity ratings: Critical / High / Medium / Low / Informational
  • Bounty table: understand triage SLA, minimum payout, duplicates policy

MODULE 02: Environment Setup & Tooling
Your hacking environment is your workshop. Build it right once and it will serve you for years. This module covers OS setup, essential tools, browser configuration, and proxy setup.

MODULE 03: Reconnaissance — The Foundation of Hunting
70% of successful bug bounty findings come from thorough reconnaissance. Hunters who skip recon find the same endpoints as everyone else. Deep recon reveals forgotten assets, shadow IT, and unique attack surfaces.

MODULE 04: Cross-Site Scripting (XSS)
XSS remains one of the most reported bug classes. Understanding all three types deeply — and knowing when each is exploitable for real impact — is essential for consistent bounties.

MODULE 05: SQL Injection
SQL injection can lead to complete database compromise, authentication bypass, and in some cases remote code execution. Despite being well-known, SQLi still appears regularly in bug bounty programs.

MODULE 06: IDOR & Broken Access Control
Insecure Direct Object Reference (IDOR) and broken access control are consistently the #1 most rewarded vulnerability class on bug bounty platforms. They require creativity and deep understanding of application logic rather than automated tools.

MODULE 07: Server-Side Request Forgery (SSRF)
SSRF is one of the highest-impact vulnerabilities in cloud environments. It can expose internal services, cloud metadata APIs, and in chained scenarios lead to full server compromise and AWS credential theft.

MODULE 08: Other Critical Vulnerability Classes
A well-rounded hunter needs to recognize and exploit a broad range of vulnerability types. This module covers XXE, SSTI, Open Redirect, CSRF, Business Logic flaws, and Subdomain Takeover.

MODULE 09: API Security Testing
Modern applications are API-first. REST APIs, GraphQL endpoints, and WebSockets present unique attack surfaces that require specialized testing techniques beyond traditional web vulnerability hunting.

MODULE 10: Vulnerability Chaining & Business Logic
Individual vulnerabilities rated Medium can chain to Critical findings. Business logic flaws are unique to each application and cannot be found with automated tools — they require understanding the application's intended flow and breaking it creatively.

MODULE 11: Writing Reports That Get Paid
A brilliant finding poorly reported may be triaged as duplicate or Invalid. A solid finding with an excellent report gets paid quickly, earns bonuses, and builds your reputation on the platform. Report writing is a skill as important as finding bugs.

MODULE 12: Mobile & Thick Client Testing
Mobile applications represent a growing attack surface with unique vulnerability classes. This module covers Android APK analysis, iOS basics, certificate pinning bypass, and thick client testing fundamentals.

MODULE 13: Automation & Building Your Toolkit
Top earners on bug bounty platforms automate the repetitive parts of hunting so they can focus on creative thinking. This module covers building pipelines, notification systems, and custom wordlists.

MODULE 14: Career, Strategy & Getting Paid Consistently
Technical skills alone do not make a successful bug bounty hunter. This final module covers program selection strategy, building reputation, handling disputes, tax considerations, and transitioning to full-time or part-time hunting.
