Hands-On Penetration Testing on Windows

By: Phil Bramwell

Overview of this book

Windows has always been the go-to platform for users around the globe to perform administration and ad hoc tasks, in settings that range from small offices to global enterprises, and this massive footprint makes securing Windows a unique challenge. This book will enable you to distinguish yourself to your clients. In this book, you'll learn advanced techniques to attack Windows environments from the indispensable toolkit that is Kali Linux. We'll work through core network hacking concepts and advanced Windows exploitation techniques, such as stack and heap overflows, precision heap spraying, and kernel exploitation, using coding principles that allow you to leverage powerful Python scripts and shellcode. We'll wrap up with post-exploitation strategies that enable you to go deeper and keep your access. Finally, we'll introduce kernel hacking fundamentals and fuzzing testing, so you can discover vulnerabilities and write custom exploits. By the end of this book, you'll be well-versed in identifying vulnerabilities within the Windows OS and developing the desired solutions for them.

Hack tunnels – netcat backdoors on the fly


I can hear what you're thinking. You're wondering whether netcat is really a good idea for this purpose. It isn't an encrypted tunnel with any authentication mechanism, and nc.exe is notoriously flagged by AV software. Well, we're running with netcat for now because it makes for a nice demonstration, but there is a practical purpose: I'm not sure there's anything quite as fast as this method for creating a persistent backdoor into a shell session on a Windows target. Nevertheless, you can leverage this method with any listener you like.

Uploading and configuring persistent netcat with meterpreter

We've seen the easy way to transfer files over the LAN with SimpleHTTPServer. This time, we're assuming a Meterpreter foothold has been established and we're just setting up a quicker, callback number.

 

 

Use the upload command to get your backdoor on to the target. Next, the part that makes this happen with every boot: adding the executable to the registry...
