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.

Chapter 6: File Recovery and Data Carving with foremost, Scalpel, and bulk_extractor

Now that we've learned how to create forensic images of evidence, let's take a look at the file recovery and data carving process using foremost, Scalpel, and bulk_extractor.

When we last covered filesystems, we saw that various operating systems use their own filesystems to store, access, and modify data. Storage media also uses filesystems to do the very same thing.

Metadata, or "data about data," helps the operating system identify data. Metadata includes technical information, such as the creation and modification dates and the file type of the data. This data makes it much easier to locate and index files.

File carving retrieves data and files from unallocated space using specific characteristics, such as the file structure and file headers, instead of traditional metadata created by or associated with filesystems.

As the name implies, unallocated space is an area...
