Mastering Modern Web Penetration Testing

By: Prakhar Prasad, Rafay Baloch

Overview of this book

Web penetration testing is a growing, fast-moving, and absolutely critical field in information security. This book executes modern web application attacks and utilises cutting-edge hacking techniques with an enhanced knowledge of web application security. We will cover web hacking techniques so you can explore the attack vectors during penetration tests. The book encompasses the latest technologies such as OAuth 2.0, Web API testing methodologies and XML vectors used by hackers. Some lesser discussed attack vectors such as RPO (relative path overwrite), DOM clobbering, PHP Object Injection and etc. has been covered in this book. We'll explain various old school techniques in depth such as XSS, CSRF, SQL Injection through the ever-dependable SQLMap and reconnaissance. Websites nowadays provide APIs to allow integration with third party applications, thereby exposing a lot of attack surface, we cover testing of these APIs using real-life examples. This pragmatic guide will be a great benefit and will help you prepare fully secure applications.

Reverse IP Lookup – YouGetSignal


The YouGetSignal (http://www.yougetsignal.com/) is a website that provides a reverse IP lookup feature. In layman's terms, the website will try to obtain the IP address for every hostname entered and then it will do a reverse IP lookup on it, so it will discover other hostnames that are associated with that particular IP. A classic situation is when the website is hosted on a shared server. If we had the task of penetrating a website, then we could do a reverse lookup for the website hostname on YouGetSignal and then attempt to break into other sites (if in scope). Then we could escalate privileges to get into the target website hosted on the same server.

For demonstration purposes, I'll do a reverse IP lookup through YouGetSignal on www.packtpub.com.

The YouGetSignal gave us a list of possible domains that are hosted on the same server.
