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.

Branching instructions

This is the last important set of instructions to learn. These instructions are related to branching and conditional jumps. These instructions are not so different from the assembly languages either, but they depend on the stack values for comparing and branching:

call Calls a method or a static method of a class
callvirt Calls a method of an object (the object reference needs to be pushed to the stack earlier)
ret Return from a method
jmp Exit the current method and jump to a specific method (given the ID of that method)
beq and bne Branch if equal and branch if not equal (given the line number of the target instruction to branch to)
blt and ble Branch if lower and branch if lower or equal
bgt and bge Branch if greater and branch if greater or equal
brfalse Branch if the result is False (other aliases include brzero and brnull)
brtrue Branch if the result is True (other aliases include brinst)
br (br.s) Branch to target given the line number...
