Overview of this book

Kali Linux is a Linux-based distribution that's widely used for penetration testing and digital forensics. It has a wide range of tools to help for digital forensics investigations and incident response mechanisms. This updated second edition of Digital Forensics with Kali Linux covers the latest version of Kali Linux and The Sleuth Kit. You'll get to grips with modern techniques for analysis, extraction, and reporting using advanced tools such as FTK Imager, hex editor, and Axiom. Updated to cover digital forensics basics and advancements in the world of modern forensics, this book will also delve into the domain of operating systems. Progressing through the chapters, you'll explore various formats for file storage, including secret hiding places unseen by the end user or even the operating system. The book will also show you how to create forensic images of data and maintain integrity using hashing tools. Finally, you'll cover advanced topics such as autopsies and acquiring investigation data from networks, operating system memory, and quantum cryptography. By the end of this book, you'll have gained hands-on experience of implementing all the pillars of digital forensics: acquisition, extraction, analysis, and presentation, all using Kali Linux tools.

Live acquisition versus post-mortem acquisition

When investigating devices that are powered on and powered off, special consideration must be given to the volatility of data. Booting, rebooting, or shutting down a device can cause data to be written to the hard drive, resulting in data (deleted files) in unallocated space being overwritten.

Powered-on devices

Before we begin any examination of live systems, it is of high importance that all steps be thoroughly documented, particularly if the report and evidence are to be presented in court. Investigating a live system means that logs and timestamps will be generated while the system is being examined. Therefore, thorough documentation will justify the actions taken by the forensic examiner and not be viewed as evidence tampering.

When investigating a powered-on device, the following precautions should be taken:

  • Move the mouse or glide your fingers across the touchpad if you suspect the device may be in a sleep state...
