Masterclass Tutorial: Bug Bounty

Nuclei is the cheat code. It has 4,000+ vulnerability templates. If a bug was reported anywhere in the world, Nuclei probably has a template for it. Run it every morning while you have coffee.

Modern apps are React/Vue heavy. All logic lives in .js files. Download these files and grep for:

Masterclass Tip: Use grep -Eo "(https?://)[a-zA-Z0-9./?=_-]*" on JS files to find hidden API endpoints.

You found a bug. You are excited. But if you write a bad report, the triager will mark it as "Informative" or "N/A." You get $0.

Is there an /admin panel? A /swagger-ui.html (API docs)? A /graphql (GraphQL endpoint)?

# Use ffuf with a high-quality wordlist (SecLists)
ffuf -u https://redacted.com/FUZZ -w /path/to/SecLists/Discovery/Web-Content/common.txt -c -t 200

Masterclass Insight: Don't just look for 200 OK. Look for 403 Forbidden or 401 Unauthorized. These mean the folder exists—sometimes you can bypass the auth.

# Step 1: Subdomain discovery + probing
subfinder -d target.com | httpx | tee live_hosts.txt
Hackers often say, "Bug bounty is just luck."
That is a lie.
Luck is when preparation meets opportunity. The "lucky" hunter who finds a critical RCE in 10 minutes? They spent 1,000 hours building a reconnaissance pipeline that finds swagger.yaml files others miss.

Whether you are a beginner looking for your first payout or an experienced researcher refining your methodology, this bug bounty masterclass tutorial provides a strategic roadmap for success in 2026. 1. The Foundation: Understanding the Ecosystem
A bug bounty program is a formal invitation for ethical hackers to test a company's systems for vulnerabilities in exchange for rewards. Before you start, familiarize yourself with these key pillars:
The Platforms: Most hunters start on established platforms like HackerOne (best for depth and reliability) and Bugcrowd.
The Scope: This defines what you are allowed to test (e.g., specific domains, mobile apps, or APIs). Testing out-of-scope assets is a violation of ethics and rules.
Rules of Engagement: These detail allowed testing methods and forbidden actions (e.g., DoS attacks are typically banned).
Reward Structure: Shows the potential payouts, which can range from $100 for low-impact bugs to over $100,000 for critical findings at companies like Amazon or Epic Games. 2. Crafting Your Methodology
Success in bug bounty hunting is 80% preparation and 20% exploitation. A professional methodology follows these steps: Step 1: Reconnaissance (The Data Phase) Recon is about finding what others missed. Modern apps are React/Vue heavy
Subdomain Discovery: Use Subfinder for passive enumeration and Amass for complex infrastructure mapping.
Service Probing: Use Httpx to identify live web services and Nmap for scanning non-standard ports (e.g., 8080, 9200).
Content Discovery: Use Waybackurls to find historical endpoints or FFUF for fast directory and parameter fuzzing. Step 2: Vulnerability Analysis (The Hunting Phase) 8 Best Bug Bounty Platforms to Join In 2026 - CloudSEK
