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.

Memory forensics techniques for process injection

Since one of the main reasons to use process injection is to hide malware presence from memory forensics tools, it gets quite tricky to detect it using them. In this section, we will take a look at different techniques that we can use to detect different types of process injections.

Here, we will be using a tool called Volatility. This tool is a free, open source program for memory forensics that can analyze memory dumps from infected machines. So, let’s get started.

Technique 1 – Detecting code injection and reflective DLL injection

The main red flag that helps us to detect injected code inside a process is that the allocated memory that contains the shellcode or the loaded DLL always has the EXECUTE permission and doesn’t represent a mapped file. When a module (an executable file) gets loaded using the Windows PE loader, it gets loaded with an IMAGE flag to represent that it’s a memory map of an...
