Black Hat JavaScript: Advanced Client-Side Exploitation, Reverse Engineering, and Penetration Testing Techniques for Web Hackers
Can a few lines of JavaScript really compromise an entire web application?
Yes—and this book shows you exactly how it’s done.
Black Hat JavaScript is the definitive guide to weaponizing the most ubiquitous language on the web for offensive security. Written by a seasoned red teamer, this book takes you deep into the browser to reveal how attackers exploit real-world applications using advanced client-side techniques—from DOM-based XSS and prototype pollution to full attack chains leveraging browser APIs, automation, and obfuscated logic.
This isn’t about centering divs or writing clean UI code. It’s about exploiting the overlooked, manipulating the exposed, and understanding how the browser becomes the new battlefield.
What You’ll Learn Inside
How to reverse engineer JavaScript-heavy SPAs using browser DevToolsAdvanced XSS payloads and mutation-based attacks that bypass CSPBreaking frontend authentication, session handling, and JWT logicExploiting client-side vulnerabilities like prototype pollution and insecure storageCrafting phishing lures and exfil payloads using Service Workers and postMessageUsing tools like Puppeteer and Playwright for automated client-side reconAttacking the frontend supply chain via third-party scripts and misconfigured CDNsBuilding red team payloads that persist in real browsersWho This Book Is For
Penetration testers targeting modern JavaScript appsRed team operators building stealthy client-side payloadsBug bounty hunters tackling SPAs, API-heavy apps, and obfuscated JSSecurity engineers and defenders who need to understand attacker workflowsCurious developers who already write JavaScript—and want to know how it can be abusedIf you're comfortable with JavaScript, understand basic web security, and want to level up into real-world client-side exploitation, this book is your technical roadmap.
Why This Book Stands Out
Hands-on examples, payloads, and scripts you can use and adaptModular chapters covering both offensive tactics and defensive insightsA full final exploit, automate, and secure a vulnerable web appAuthored by an experienced offensive security practitioner, with a strong focus on modern threatsUp-to-date for current browser APIs, frontend frameworks, and attack vectors in 2025Don’t Let the Browser Be the Blind Spot in Your Security Strategy
Master offensive JavaScript techniques used by real attackers—and learn to think like one.
