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. Code Injection Techniques


As mentioned earlier, the objective of a code injection technique is to inject code into the remote process memory and execute the injected code within the context of a remote process. The injected code could be a module such as an executable, DLL, or even shellcode. Code injection techniques provide many benefits for attackers; once the code is injected into the remote process, an adversary can do the following things:

  • Force the remote process to execute the injected code to perform malicious actions (such as downloading additional files or stealing keystrokes).
  • Inject a malicious module (such as a DLL) and redirect the API call made by the remote process to a malicious function in the injected module. The malicious function can then intercept the input parameters of the API call, and also filter the output parameters. For example, Internet Explorer uses HttpSendRequest() to send a request containing an optional POST payload to the web server, and it uses InternetReadFile...
