Overview of this book

New and developing technologies inevitably bring new types of malware with them, creating a huge demand for IT professionals that can keep malware at bay. With the help of this updated second edition of Mastering Malware Analysis, you’ll be able to add valuable reverse-engineering skills to your CV and learn how to protect organizations in the most efficient way. This book will familiarize you with multiple universal patterns behind different malicious software types and teach you how to analyze them using a variety of approaches. You'll learn how to examine malware code and determine the damage it can possibly cause to systems, along with ensuring that the right prevention or remediation steps are followed. As you cover all aspects of malware analysis for Windows, Linux, macOS, and mobile platforms in detail, you’ll also get to grips with obfuscation, anti-debugging, and other advanced anti-reverse-engineering techniques. The skills you acquire in this cybersecurity book will help you deal with all types of modern malware, strengthen your defenses, and prevent or promptly mitigate breaches regardless of the platforms involved. By the end of this book, you will have learned how to efficiently analyze samples, investigate suspicious activity, and build innovative solutions to handle malware incidents.

DKOM

DKOM is one of the most common techniques used by rootkits to hide malicious user-mode processes. This technique relies on how the OS represents processes and threads. To understand this technique, you need to learn more about the objects that are being manipulated by the rootkit: EPROCESS and ETHREAD.

The kernel objects – EPROCESS and ETHREAD

Windows creates an object called EPROCESS for each process that's created in the system. This object includes all the important information about this process, such as its Virtual Address Descriptors (VADs), which store the map of this process's virtual memory and its representation in physical memory. It also includes the process ID, the parent process ID, and a doubly linked list called ActiveProcessLinks, which connects all EPROCESS objects of all processes. Each EPROCESS includes an address to the next EPROCESS object (which represents the next process) called FLink and the address to the previous EPROCESS object...
