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.

7. Dumping an Executable and DLL


After you have identified the malicious process or DLL, you may want to dump it for further investigation (such as for extracting strings, running yara rules, disassembly, or scanning with Antivirus software). To dump a process executable from memory to disk, you can use the procdump plugin. To dump the process executable, you need to know either its process ID or its physical offset. In the following example of a memory image infected with Perseus malware (covered previously while discussing the pslist plugin), the procdump plugin is used to dump its malicious process executable svchost..exe (pid 3832). With the -D (--dump-dir) option, you specify the name of the directory in which to dump executable files. The dumped file is named based on the pid of a process such as executable.PID.exe:

$ python vol.py -f perseus.vmem --profile=Win7SP1x86 procdump -p 3832 -D dump/
