Practical Memory Forensics

Book excerpt: A practical guide to enhancing your digital investigations with cutting-edge memory forensics techniques Key FeaturesExplore memory forensics, one of the vital branches of digital investigationLearn the art of user activities reconstruction and malware detection using volatile memoryGet acquainted with a range of open-source tools and techniques for memory forensicsBook Description Memory Forensics is a powerful analysis technique that can be used in different areas, from incident response to malware analysis. With memory forensics, you can not only gain key insights into the user's context but also look for unique traces of malware, in some cases, to piece together the puzzle of a sophisticated targeted attack. Starting with an introduction to memory forensics, this book will gradually take you through more modern concepts of hunting and investigating advanced malware using free tools and memory analysis frameworks. This book takes a practical approach and uses memory images from real incidents to help you gain a better understanding of the subject and develop the skills required to investigate and respond to malware-related incidents and complex targeted attacks. You'll cover Windows, Linux, and macOS internals and explore techniques and tools to detect, investigate, and hunt threats using memory forensics. Equipped with this knowledge, you'll be able to create and analyze memory dumps on your own, examine user activity, detect traces of fileless and memory-based malware, and reconstruct the actions taken by threat actors. By the end of this book, you'll be well-versed in memory forensics and have gained hands-on experience of using various tools associated with it. What you will learnUnderstand the fundamental concepts of memory organizationDiscover how to perform a forensic investigation of random access memoryCreate full memory dumps as well as dumps of individual processes in Windows, Linux, and macOSAnalyze hibernation files, swap files, and crash dumpsApply various methods to analyze user activitiesUse multiple approaches to search for traces of malicious activityReconstruct threat actor tactics and techniques using random access memory analysisWho this book is for This book is for incident responders, digital forensic specialists, cybersecurity analysts, system administrators, malware analysts, students, and curious security professionals new to this field and interested in learning memory forensics. A basic understanding of malware and its working is expected. Although not mandatory, knowledge of operating systems internals will be helpful. For those new to this field, the book covers all the necessary concepts.
