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.

4. Hooking Techniques


So far, we have looked at different code injection techniques to execute malicious code. Another reason an attacker injects code (mostly DLL, but it can also be an executable or shellcode) into the legitimate (target) process is to hook the API calls made by the target process. Once a code is injected into the target process, it has full access to the process memory and can modify its components. The ability to alter the process memory components allows an attacker to replace the entries in the IAT or modify the API function itself; this technique is referred to as hooking. By hooking an API, an attacker can control the execution path of the program and re route it to the malicious code of his choice. The malicious function can then:

  • Block calls made to the API by legitimate applications (such as security products).
  • Monitor and intercept input parameters passed to the API.
  • Filter the output parameters returned from the API.

In this section, we will look at different types...
