Overview of this book

The defences continue to improve and become more and more common, but this book will provide you with a number or proven techniques to defeat the latest defences on the networks. The methods and techniques contained will provide you with a powerful arsenal of best practices to increase your penetration testing successes. The processes and methodology will provide you techniques that will enable you to be successful, and the step by step instructions of information gathering and intelligence will allow you to gather the required information on the targets you are testing. The exploitation and post-exploitation sections will supply you with the tools you would need to go as far as the scope of work will allow you. The challenges at the end of each chapter are designed to challenge you and provide real-world situations that will hone and perfect your penetration testing skills. You will start with a review of several well respected penetration testing methodologies, and following this you will learn a step-by-step methodology of professional security testing, including stealth, methods of evasion, and obfuscation to perform your tests and not be detected! The final challenge will allow you to create your own complex layered architecture with defences and protections in place, and provide the ultimate testing range for you to practice the methods shown throughout the book. The challenge is as close to an actual penetration test assignment as you can get!

Detecting load balancers


When performing a penetration test, there is the possibility that vulnerabilities left open on one server are not available on another. Proper load balancing will be almost completely transparent, which could easily lead to miscommunication of the testing results if you find any server issues on a server that is part of a pool.

Tip

We are focusing on HTTP load balancing for these exercises. Detecting DNS load balancing can be done using your enumeration tools, as described in a previous chapter. For instance, you can use dig to see if multiple servers are returned for the same domain name.

Quick reality check – Load Balance Detector

Kali includes a script named Load Balance Detector (lbd.sh) that will quickly test for load balancing. Running this tool against our current balanced Kioptrix3.com server will provide you with input that the server is not load balanced, because the tool never gets a chance to see the other server.

However, if you edit your HAProxy configuration...
