What you'll learn
Skills you'll walk away with.

- Run passive subdomain recon with gau and waybackurls
- Perform authenticated recon on real live platforms
- Intercept and replay cookie and Bearer/JWT auth flows
- Dissect JWT claims, roles, and expiry for account takeover
- Hunt Broken Access Control and IDOR in APIs and JSON

- Use Burp Repeater to isolate vulnerable endpoints
- Turn user profile updates into bug chains
- Extract hidden APIs, routes, and tokens from JavaScript

Overview
Get hunting fast.
This course starts at true zero. If you're new to security, just getting into bug bounty, or coming from dev/red team work, this is your on-ramp. You'll learn how to set up your proxy, explore real endpoints, dissect session cookies, and test for BAC and IDOR vulnerabilities that scanners and AI constantly miss.
Where does this fit with TBHM CORE? While The Bug Hunter's Methodology: CORE dives deep into advanced recon and web analysis, BAC Hero is perfect as either a pre-req or a follow-up. It fills in key fundamentals that are assumed in CORE, especially around live target setup and web basics, and adds standalone depth on BAC-style bugs that make it a strong companion no matter where you're at.

Syllabus
Ten modules, zero to hero.
Every module is hands-on and built around live targets. Expand each one to see the topics covered.
M01Course Foundations & Mental Model
- What bug bounty is, and isn't
- Building a mindset: curiosity, context, and real-world thinking
- Setting realistic goals: from $100/month to full-time
- How top hackers win: manual > automation > scanner noise
M02Browser, Burp, and the Real Web
- Using Firefox as a hacking tool
- Inspecting real requests with F12 → traffic, cookies, and endpoints
- Installing and configuring Burp Suite (with HTTPS proxying)
- The difference between GET/POST/PUT/PATCH/DELETE, and what that tells us
M03HTTP Status Codes, Cookies, and Headers
- Reading requests like a hacker
- Interpreting status codes (200 vs 403 vs 500 vs 429)
- Cookie scoping, session tracking, and CSRF markers
- How headers leak architecture, origin rules, and user state
M04Subdomain Recon, Liveliness Testing & GAU
- Discovering assets with gau, waybackurls, and passive tooling
- Checking “liveliness” and fingerprinting what's running
- Why 403 ≠ useless (and why 404s can still teach you something)
- Common missteps in scoping: what “wildcard” really means
M05Authenticated Reconnaissance on Real Targets
- Creating test accounts on live platforms (Bugcrowd, Etsy, etc.)
- Understanding the “hacker portal” vs the real user experience
- How to safely explore features like avatar uploads and settings
- Building session context before touching Burp
M06Intercepting and Analyzing Auth Flows
- Cookie-based session vs. Authorization headers (Bearer/JWT)
- Live walkthrough: setting, breaking, and replaying session tokens
- Understanding JWT payloads: claims, roles, and expiry
- Common JWT mistakes that lead to full account takeover
M07Broken Access Control (BAC) and IDOR Testing
- Manual techniques to find IDOR in APIs and JSON responses
- Reading Burp traffic: how objects, parameters, and cookies all lie
- UserID vs. UUID vs. GUID, and what's actually private
- Testing with no cookies, wrong cookies, or someone else's session
M08Logging and Repeating Bug Payloads
- Using Burp Repeater for proper test structuring
- Making sense of JSON response objects: where data hides
- Replay vs resend: why tiny changes reveal deep flaws
- How to identify and isolate vulnerable endpoints in large apps
M09Exploring LIVE Targets Like [REDACTED] and [REDACTED]
- Real-time bug hunting examples: from product listings to payment APIs
- Why “safe” endpoints (stats, analytics, avatars) often leak data
- Turning user profile updates into bug chains
- Responsible testing: how to explore without harming real users
M10Advanced Observations
- Hidden APIs from JavaScript parsing and dev tools
- Using Notepad++ to extract routes, tokens, and endpoints
- Common developer mistakes: exposed loaders, bad filters, wrong cookies
- How to build recon habits that scale with every program

Instructor
Taught by Zwink.
ZW
Zwink (the iDorminator)
#1 US-based hacker on Bugcrowd · Top 10 globally for critical impact
Zwink takes you from the absolute basics to real-world bug bounty hunting, with a spotlight on his favorite vuln class: Broken Access Control. You'll set up your proxy, explore real endpoints, dissect session cookies, and test for the BAC and IDOR vulnerabilities that scanners and AI constantly miss.
FAQ
Good to know.
What's the refund & access policy?
Because our training includes proprietary, cutting-edge content, all registrations are non-refundable. If you are unable to attend live sessions, full recordings will be provided following the conclusion of the course so you can access the material on your own schedule.
Do I need prior experience?
No. This course starts at true zero. If you're new to security, just getting into bug bounty, or coming from dev/red team work, this is your on-ramp. You'll learn proxy setup, real endpoint exploration, session cookie analysis, and BAC/IDOR testing from the ground up.
How does this fit with TBHM CORE?
While The Bug Hunter's Methodology: CORE dives deep into advanced recon and web analysis, BAC Hero is perfect as either a pre-req or a follow-up. It fills in key fundamentals that are assumed in CORE, especially around live target setup and web basics, and adds standalone depth on BAC-style bugs.
Can I make a bulk purchase?
Yes. Bulk purchases and team discounts are available. Reach out and we'll set up seats and bulk pricing for your team.
