Not all physical access is the same, though: if you convinced your target to hire you as a full-time employee, then you'll have constant physical access. How you social engineer your target is a subject for another book altogether, but for the purposes of this discussion, let's assume that you have physical access to network drops.

Once you crack that outer shell, you'll often find that the path forward seems paved especially for you-and a successful compromise will inform your client of the devastating consequences of this mistaken assumption. The candy bar model will come up in later chapters when we discuss other network attacks. In today's world, a packet hitting the border of a company's network could be from an authorized individual on a business trip, or it could be from a clever teenager in Thailand eager to try out some newly learned tricks. Packets coming in over the network were safely assumed to be from a secure environment and sent by an authorized individual. The mindset here dates back many years in the earliest days of what became the internet, the physical access points to the network were inside highly secure facilities. In other words, it's a model that emphasizes the threats of the outside world when designing the security architecture, while assuming that someone who is physically inside company facilities has been vetted and is therefore trusted.

This simply refers to a network that is tough and crunchy on the outside, but gooey on the inside. There's a design flaw concept that pen testers like to call the candy bar model. However, the pen tester can never forget the big picture. This is a field where it's very easy to get caught up in the highly specific technical details and miss the human element of security design.

The following topics will be covered in this chapter:īypassing MAC filtering – considerations for the physical assessorĪn attacker needs to be aware of methods for remote compromise: attacking the VPN, wireless infiltration from a distance using high-gain antennas, and so forth. In this chapter, we will review some of the methods employed by NACs and demonstrate practical methods of bypassing these controls. The intent of these systems is to detect and/or prevent an intrusion on the network by identifying and authenticating devices on the network. For this reason, defenders often deploy network access control( NAC) systems. The first step is getting on the network in the first place, and there are human, architectural, and protocol factors that make the mere presence of an attacker on the network potentially devastating. It's fitting, then, that we begin our journey with a discussion about compromising the network and using its own power and weaknesses to inform the pen test.

It's also what makes the compromise of a single computer effectively the compromise of an entire building full of computers. It's both the first step and the final frontier of compromising a computer. The network is the first thing we think about when we imagine computers getting hacked.

Finally, we'll introduce kernel hacking fundamentals and fuzzing testing, so you can discover vulnerabilities and write custom exploits.īy the end of this book, you'll be well-versed in identifying vulnerabilities within the Windows OS and developing the desired solutions for them.Ĭhapter 1. Bypassing Network Access Control We'll wrap up with post-exploitation strategies that enable you to go deeper and keep your access. 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. In this book, you'll learn advanced techniques to attack Windows environments from the indispensable toolkit that is Kali Linux.

This book will enable you to distinguish yourself to your clients. 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 offi ces to global enterprises, and this massive footprint makes securing Windows a unique challenge.
