Shellcoding is a technique that is executed by many red teams and used in penetration testing and real-world attacks. Books on shellcode can be complex, and writing shellcode is perceived as a kind of dark art. Offensive Shellcode from Scratch will help you to build a strong foundation of shellcode knowledge and enable you to use it with Linux and Windows.This book helps you to explore simple to more complex examples of shellcode that are used by real advanced persistent threat (APT) groups. You'll get to grips with the components of shellcode and understand which tools are used when building shellcode, along with the automated tools that exist to create shellcode payloads. As you advance through the chapters, you'll become well versed in assembly language and its various components, such as registers, flags, and data types. This shellcode book also teaches you about the compilers and decoders that are used when creating shellcode. Finally, the book takes you through various attacks that entail the use of shellcode in both Windows and Linux environments.By the end of this shellcode book, you'll have gained the knowledge needed to understand the workings of shellcode and build your own exploits by using the concepts explored.

Penetration Testing: A Survival Guide. A Survival Guide

Wolf Halton, Bo Weaver, Juned Ahmed Ansari, Srinivasa Rao Kotipalli, ...

The need for penetration testers has grown well over what the IT industry ever anticipated. Running just a vulnerability scanner is no longer an effective method to determine whether a business is truly secure. This learning path will help you develop the most effective penetration testing skills to protect your Windows, web applications, and Android devices. The first module focuses on the Windows platform, which is one of the most common OSes, and managing its security spawned the discipline of IT security. Kali Linux is the premier platform for testing and maintaining Windows security. Employs the most advanced tools and techniques to reproduce the methods used by sophisticated hackers. In this module first,you’ll be introduced to Kali's top ten tools and other useful reporting tools. Then, you will find your way around your target network and determine known vulnerabilities so you can exploit a system remotely. You’ll not only learn to penetrate in the machine, but will also learn to work with Windows privilege escalations.The second module will help you get to grips with the tools used in Kali Linux 2.0 that relate to web application hacking. You will get to know about scripting and input validation flaws, AJAX, and security issues related to AJAX. You will also use an automated technique called fuzzing so you can identify flaws in a web application. Finally, you’ll understand the web application vulnerabilities and the ways they can be exploited.In the last module, you’ll get started with Android security. Android, being the platform with the largest consumer base, is the obvious primary target for attackers. You’ll begin this journey with the absolute basics and will then slowly gear up to the concepts of Android rooting, application security assessments, malware, infecting APK files, and fuzzing. You’ll gain the skills necessary to perform Android application vulnerability assessments and to create an Android pentesting lab.This Learning Path is a blend of content from the following Packt products:• Kali Linux 2: Windows Penetration Testing by Wolf Halton and Bo Weaver• Web Penetration Testing with Kali Linux, Second Edition by Juned Ahmed Ansari• Hacking Android by Srinivasa Rao Kotipalli and Mohammed A. Imran
