Windows and Linux Penetration Testing from Scratch - Second Edition

By: Phil Bramwell

Overview of this book

Let’s be honest—security testing can get repetitive. If you’re ready to break out of the routine and embrace the art of penetration testing, this book will help you to distinguish yourself to your clients. This pen testing book is your guide to learning advanced techniques to attack Windows and Linux environments from the indispensable platform, Kali Linux. You'll work through core network hacking concepts and advanced exploitation techniques that leverage both technical and human factors to maximize success. You’ll also explore how to leverage public resources to learn more about your target, discover potential targets, analyze them, and gain a foothold using a variety of exploitation techniques while dodging defenses like antivirus and firewalls. The book focuses on leveraging target resources, such as PowerShell, to execute powerful and difficult-to-detect attacks. Along the way, you’ll enjoy reading about how these methods work so that you walk away with the necessary knowledge to explain your findings to clients from all backgrounds. Wrapping up with post-exploitation strategies, you’ll be able to go deeper and keep your access. By the end of this book, you'll be well-versed in identifying vulnerabilities within your clients’ environments and providing the necessary insight for proper remediation.

Advanced Ettercap – the man-in-the-middle Swiss Army Knife

In the previous chapter, we fooled around with ARP poisoning in Ettercap. I’m like every other normal person: I love a good ARP spoof. However, it’s infamously noisy. It just screams, HEY! I’M A BAD GUY, SEND ME ALL THE DATA! Did you fire up Wireshark during the attack? Even Wireshark knows that something is wrong and warns the analyst that duplicate use has been detected! It’s the nature of the beast when we’re convincing the network to send everything to a single interface – what is called unified sniffing.

Now, we’re going to take man-in-the-middle to the next level with bridged sniffing, which is bridging together two interfaces on our Kali box and conducting our operations between the two interfaces. Those interfaces are local to us and bridged together, all on the fly, by Ettercap; in other words, a user won’t see anything amiss. We aren’t telling...
