This chapter is all about investigating malware in the context of network forensics. Most of the incidents requiring network forensics will be based on malware-oriented events, such as network breaches, financial crime, data theft, and command and control. Most of the attackers will deploy command and control malware to enslave the compromised machine and gain leverage over the internal network for lateral movement. Generally, network forensics and computer forensics go hand in hand in case of investigating malware. The computer forensics investigator will find all that has changed on the system and where the malware resides in the system. Then, they will find the executables causing the issues and upload them to a site, such as https://www.virustotal.com or http://www.hybrid-analysis.com, to find more about the malware and...

Overview of this book
Network forensics is a subset of digital forensics that deals with network attacks and their investigation. In the era of network attacks and malware threat, it’s now more important than ever to have skills to investigate network attacks and vulnerabilities.
Hands-On Network Forensics starts with the core concepts within network forensics, including coding, networking, forensics tools, and methodologies for forensic investigations. You’ll then explore the tools used for network forensics, followed by understanding how to apply those tools to a PCAP file and write the accompanying report. In addition to this, you will understand how statistical flow analysis, network enumeration, tunneling and encryption, and malware detection can be used to investigate your network. Towards the end of this book, you will discover how network correlation works and how to bring all the information from different types of network devices together.
By the end of this book, you will have gained hands-on experience of performing forensics analysis tasks.
