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.

SuperH

SuperH (also known as Renesas SH) is a collective name of several instruction sets (SH-1/SH-2/SH-2A/...), so it makes sense to double-check which one exactly needs to be emulated. Most samples should work just fine on the SH4 as these CPU cores are supposed to be upward-compatible. This architecture is not the top choice for both attackers or reverse engineers, so the range of available tools might be more limited. For static analysis, it makes sense to stick to solutions such as radare2, IDA, or ODA. Since IDA doesn't seem to provide remote GDB debugger functionality for this architecture, dynamic analysis has to be handled through QEMU and either radare2 or GDB, the same way as we described earlier:

If, for some reason, the binary emulation doesn't work properly, then it may make sense to obtain real hardware and perform debugging either there or remotely using the...
