Web Application Advanced Hacking
Web Application Advanced Hacking
A Hands-On Field Guide to latest techniques used by security researchers and bug bounty hunters
About the Book
No matter if you're veteran or newcomer to the security field, the key technologies used in today’s web applications are rapidly changing—with more and more data stored in the cloud and applications based on cutting-edge, open-source technologies, penetration testing and security engagement processes have naturally become more complicated.
This book intends to be hands-on and highly practical guide to enhancing your knowledge on modern application stacks. It will help to fill knowledge gaps when it comes to hacking modern web applications by using advanced techniques such as manually identifying and exploiting vulnerabilities for:
- NoSQL databases
- JSON Web Token (JWT) & OAuth2.0 Protocols
- Cloud Storage
- Advanced Server-Side Request Forgery (SSRF)
- Application Logical flaws
- and much more...
All covered in this book using real-life examples!
The skills you gain from this book will help you to expand the scope of your customers' engagements and increase your value as a security professional (or “white-hacker,” as some prefer to be called), as this book will help you dive deep into the underlying concepts beneath pentesting tools.
