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.

8. Listing Network Connections and Sockets


Most malicious programs perform some network activity, either to download additional components, to receive commands from the attacker, to exfiltrate data, or to create a remote backdoor on the system. Inspecting the networking activity will help you determine the network operations of the malware on the infected system. In many cases, it is useful to associate the process running on the infected system with the activities detected on the network. To determine the active network connections on pre-vista systems (such as Windows XP and 2003), you can use the connections plugin. The following command shows an example of using the connections plugin to print the active connections from a memory dump infected with BlackEnergy malware. From the following output, you can see that the process with a process ID of 756 was responsible for the C2 communication on port 443. After running the pslist plugin, you can tell that the pid of 756 is associated with...
