Digital Forensics with Kali Linux - Second Edition

By: Shiva V. N. Parasram

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.

Write blocking

Once our evidence has been properly documented and collected, we can begin working on acquiring the actual digital evidence. I'll mention this a couple times in an effort to drive home the point, but the original evidence should only be used to create forensic copies or images, which will be discussed further on in this chapter and again in other chapters.

Working on the original evidence can, and usually will, modify the contents of the medium. For instance, booting a seized laptop into its native OS will allow data to be written to the hard drive and may also erase and modify the contents contained in RAM and the paging file.

To prevent this from happening, the use of a write blocker must be employed. Write blockers, as the name suggests, prevent data from being written to the evidence media. Write blockers can be found in both hardware and software types. If a hardware write blocker is not available, software versions are readily available as standalone...
