The Web Application Hacker's Handbook

Finding and Exploiting Security Flaws

Dafydd Stuttard, Marcus Pinto

The exhaustive reference for web app pentesting, comprehensive but increasingly a historical document.

Read this if

Pentesters and bug bounty hunters who realized that most production attack surface is now API, not HTML. Ball's structured approach covers REST, GraphQL discovery, BOLA, mass assignment, JWT abuses, and the operational tooling around them.

Anyone moving from CTF web challenges into real engagements who needs a systematic mental model of attack surface.

Skip this if

Readers who want generalist web security; the book is API-focused and assumes you already understand OWASP-class web bugs.

Frontend-heavy apps in 2024. SPA-specific bugs, JWT pitfalls, GraphQL, and modern CSP are barely covered or absent entirely.

Key takeaways

API attack surface is dramatically underexploited compared to HTML attack surface; for most public bug bounty programs, the API is where the bounties hide.
BOLA (broken object-level authorization) is the dominant API bug class and the one that pays best; Ball's framing is the cleanest in print.
Burp Suite Professional + Postman + a custom recon pipeline is the practical toolset; the book justifies the choice and shows you how to use them together.

Authentication, session management, and access control are still where most real bugs live.
Methodology beats tooling, the structure of how you map an app matters more than which scanner you run.
Use it as a reference for the classes of bug, then cross-check with PortSwigger Academy for the modern exploitation details.

How they compare

Hacking APIs and The Web Application Hacker's Handbook are both rated 4/5 in our catalog. Pick by topic preference and reading style rather than by rating.

Both books target intermediate-level readers, so the choice is about topic, not difficulty.

Hacking APIs and The Web Application Hacker's Handbook both cover Web Security, AppSec, Offensive, so reading them in sequence reinforces the same material from different angles.
