Mastering Malware Analysis

By: Alexey Kleymenov, Amr Thabet

Overview of this book

With the ever-growing proliferation of technology, the risk of encountering malicious code or malware has also increased. Malware analysis has become one of the most trending topics in businesses in recent years due to multiple prominent ransomware attacks. Mastering Malware Analysis explains the universal patterns behind different malicious software types and how to analyze them using a variety of approaches. You will learn how to examine malware code and determine the damage it can possibly cause to your systems to ensure that it won't propagate any further. Moving forward, you will cover all aspects of malware analysis for the Windows platform in detail. Next, you will get to grips with obfuscation and anti-disassembly, anti-debugging, as well as anti-virtual machine techniques. This book will help you deal with modern cross-platform malware. Throughout the course of this book, you will explore real-world examples of static and dynamic malware analysis, unpacking and decrypting, and rootkit detection. Finally, this book will help you strengthen your defenses and prevent malware breaches for IoT devices and mobile platforms. By the end of this book, you will have learned to effectively analyze, investigate, and build innovative solutions to handle any malware incidents.

Decompiling

Instead of restoring the assembly instructions, this set of tools restores the source code, which is usually a more human-friendly option:

  • JADX: DEX to Java decompiler. It provides both a command-lines and a GUI tool to obtain close to the original source code in the Java language. In addition, it provides basic deobfuscation functionality:

  • AndroChef: This commercial decompiler supports both Java and Android files and provides a handy GUI to go through the results.
  • JEB decompiler: Another powerful commercial disassembling and decompiling solution, this supports both Dalvik and machine code.
  • dex2jar: While not exactly a decompiler, this tool allows engineers to convert DEX files to JARs. After that, it becomes possible to use multiple Java decompilers to obtain Java source code, which has already been discussed in Chapter 8, Reversing Bytecode Languages: .NET, Java, and More.
  • Ghidra: In addition to native executables, this powerful...
