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.

10. Investigating Service


In Chapter 7, Malware Functionalities and Persistence, we looked at how an attacker can persist on the system by installing on or modifying an existing service. In this section, we will focus on how to investigate services from the memory image. To list the services and their information such as display name, type of service, and startup type from the memory image, you can use the svcscan plugin. In the following example, the malware creates a service of type WIN32_OWN_PROCESS with the display name and service name as svchost. From the binary path, you can tell that the svchost.exe is malicious because it is running from the non-standard path C:\Windows instead of C:\Windows\System32:

$ python vol.py -f svc.vmem --profile=Win7SP1x86 svcscan
