Overview of this book

Malware analysis and memory forensics are powerful analysis and investigation techniques used in reverse engineering, digital forensics, and incident response. With adversaries becoming sophisticated and carrying out advanced malware attacks on critical infrastructures, data centers, and private and public organizations, detecting, responding to, and investigating such intrusions is critical to information security professionals. Malware analysis and memory forensics have become must-have skills to fight advanced malware, targeted attacks, and security breaches. This book teaches you the concepts, techniques, and tools to understand the behavior and characteristics of malware through malware analysis. It also teaches you techniques to investigate and hunt malware using memory forensics. This book introduces you to the basics of malware analysis, and then gradually progresses into the more advanced concepts of code analysis and memory forensics. It uses real-world malware samples, infected memory images, and visual diagrams to help you gain a better understanding of the subject and to equip you with the skills required to analyze, investigate, and respond to malware-related incidents.

3. Data Transfer Instructions


One of the basic instructions in the assembly language is the mov instruction. As the name suggest, this instruction moves data from one location to another (from source to destination). The general form of the mov instruction is as follows; this is similar to the assignment operation in a high-level language:

mov dst,src

There are different variations of the mov instruction, which will be covered next.

3.1 Moving a Constant Into Register

The first variation of the mov instruction is to move a constant (or immediate value) into a register. In the following examples, ; (a semicolon) indicates the start of the comment; anything after the semicolon is not part of the assembly instruction. This is just a brief description to help you understand this concept:

mov eax,10  ; moves 10 into EAX register, same as eax=10
mov bx,7    ; moves 7 in bx register, same as bx=7
mov eax,64h ; moves hex value 0x64 (i.e 100) into EAX

3.2 Moving Values From Register To Register
