Web Application Hacking L2

Description

Advanced Web App Penetration Testing, API Security, Bug Bounty & Secure Code Review

Go from intermediate to advanced. Learn to find the high-impact bugs that scanners miss and beginners never see.

Web Application Hacking L2 is a 501-page, hands-on guide to advanced web application penetration testing, bug bounty hunting, and secure development. It picks up exactly where the fundamentals leave off and teaches you to think the way professional application-security consultants do — in trust boundaries, capability chaining, and real attack paths — so you can find, prove, and report the vulnerabilities that actually matter.

This isn’t a list of payloads. Every vulnerability is broken down with its theory, root cause, architecture, a realistic attack scenario, and the exact HTTP requests — then paired with the defense, so you understand both sides of every technique.

Who This Book Is For

• Aspiring and working penetration testers who want to level up from basic vulnerabilities to advanced, chained attacks
• Bug bounty hunters who want a repeatable methodology that finds bugs others miss and avoids duplicates
• Security engineers and AppSec professionals sharpening their offensive and defensive skills
• Developers who want to write more secure code by understanding how apps really get attacked

Prerequisites: You should already know HTTP, Burp Suite, and basic vulnerabilities like XSS and SQL injection. If you’ve finished a Level 1 / fundamentals course, you’re ready.

📘 New to web hacking? Start with Web Application Hacking L1 — the beginner’s guide that builds your foundation. Already comfortable with HTTP, Burp Suite, and basic vulnerabilities? You’re ready for L2.

What You’ll Learn

Part I — Advanced Web Architecture Trust boundaries, microservices, APIs, real-time channels, and modern transport — the mental model that powers every attack in the book.

Part II — Advanced Reconnaissance Subdomain enumeration, JavaScript and source-map mining, exposed secrets and leaked credentials, perimeter mapping, and API discovery.

Part III — Business Logic Testing Race conditions, e-commerce and payment flaws, refund and workflow abuse, and account-lifecycle attacks that no scanner can find.

Part IV — Advanced Authentication JWT attacks, OAuth 2.0 and OpenID Connect exploitation, passwordless and magic-link flaws, MFA bypass, and full account-takeover chains.

Part V — Advanced Authorization IDOR, BOLA, BFLA, mass assignment, and multi-tenant isolation failures — the #1 category of serious modern web bugs.

Part VI — Advanced API Security REST and GraphQL exploitation, WebSocket attacks, file-upload abuse, resource-consumption attacks, and the complete OWASP API Security Top 10.

Part VII — Injection & Input-Based Attacks SQL and NoSQL injection, server-side template injection (SSTI), XPath/LDAP injection, and prototype pollution.

Part VIII — Server-Side Attacks SSRF to cloud credential theft, XXE, path traversal and LFI-to-RCE, HTTP request smuggling, cache poisoning, and host-header attacks.

Part IX — Secure Code Review Source-to-sink analysis, the dangerous-sink catalogue, and structural fixes that eliminate whole vulnerability classes — not just single bugs.

Part X — Bug Bounty & Professional Practice Program selection, recon at scale, prioritization, minimal-proof discipline, evidence collection, and writing reports that get paid.

Part XI — Detection & Defense The blue-team view of every attack: threat modeling, what each attack looks like in logs, detection engineering, and layered defense.

Part XII — Professional Reporting Executive summaries, risk narratives, CVSS and severity, evidence annotation, and remediation that lands.

What’s Inside

• 501 pages of in-depth, practical content
• 12 parts and 80 chapters built to a professional quality standard
• 8 quick-reference cheat sheets — OWASP Top 10, OWASP API Top 10, HTTP, Burp Suite, JWT, OAuth 2.0, GraphQL, and REST
• 6 professional checklists — business logic testing, web pentesting, bug bounty workflow, reporting templates, secure code review, and developer security
• A 707-term security glossary — the complete vocabulary of the field
• Real attack scenarios with annotated HTTP requests and responses
• Hands-on labs and worked case studies that chain multiple flaws into real impact
• A fully navigable table of contents with page numbers

Why This Book Is Different

• Depth over lists. Every vulnerability includes theory, root cause, architecture, attack scenario, and real HTTP — so you understand why it works, not just what to type.
• Attack chaining. You’ll learn to combine individually “medium” bugs into critical, high-payout findings — the skill that separates top hunters from the crowd.
• Offense and defense. Every attack is mirrored with its detection and fix, making the book valuable for pentesters, defenders, and developers alike.
• Standards-aligned. Maps directly to OWASP Top 10, OWASP API Security Top 10, and ASVS — the frameworks employers and clients care about.
• Responsible by design. A strong “minimal proof” and authorized-testing ethic runs through every chapter.

Ethical Use

Everything in this book is for authorized, legal security testing only — your own labs, bug bounty programs with explicit scope, and professional penetration-testing engagements. The book teaches responsible disclosure and minimal-impact proof throughout. Scope is the law.
