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.

11. Extracting Command History


After compromising the system, an attacker may execute various commands on the command shell to enumerate users, groups, and shares on your network, or an attacker may transfer a tool such as Mimikatz (https://github.com/gentilkiwi/mimikatz) to the comprised system and execute it to dump Windows credentials. Mimikatz is an open source tool that was written by Benjamin Delpy in 2011. It is one of the most popular tools for gathering credentials from Windows systems. Mimikatz is distributed in different flavors, such as the compiled version (https://github.com/gentilkiwi/mimikatz), and is part of PowerShell Modules such as PowerSploit (https://github.com/PowerShellMafia/PowerSploit) and PowerShell Empire (https://github.com/EmpireProject/Empire).

Command history can provide valuable information about an attacker's activity on the compromised system. By examining the command history, you can determine information such as the commands that have been executed, programs...
