In this blogpost, we will dive into the concepts of disk images and how digital forensics examiners can use the Exhume toolkit to read data transparently from different formats. First, we will give an overview of what is a disk image and describe some of the existing formats one may encounter during a digital investigation. Next, we will explore how Exhume Body is providing an abstraction layer to those formats to read data agnostically.

πŸ”¦ A quick walkthrough in the VMDK format

After attending a conference for incident response teams, I joined a project aiming to create a forensic framework allowing acquisition and visualization of evidence from various sources: the Exhume toolkit.

The Exhume Toolkit v0.1

In this quest of retrieving data from various base formats, I got involved in the understanding and implementation of a parser for the VMDK format.

The Virtual Machine Disk format has been created by VMware and is used by all kinds of virtual machines from all types of hypervisors. It is also used in exchange formats used to share virtual machines from one hypervisor to another.

Most IT experts, from cybersecurity to system administrators have heard of VMDK files. And I am no exception. But I never really understood what was behind this format. Sure, I did encounter some difficulties to access data from a VMDK file sourced from and ESXi server but I always found tools allowing to convert the file to a better suited format... Including VMDK itself.

At that moment I wondered why converting a VMDK file to another one could help me get access to the data for forensic purposes. And I've found the answer now I did some serious research on the matter.

πŸ¦‰ Thanatology Part 1 - Introducing the Thanatology project

In digital forensics, tools are only as valuable as the investigator’s ability to understand and explain their output, especially when presenting evidence in court. Beyond simply extracting data, the methodology behind how artifacts are collected and interpreted plays a critical role in admissibility, reliability and credibility.

This blog post series introduces the Thanatology Project, an open-source, cross-platform digital forensics framework currently under development. Built on top of the Exhume ToolKit (a modular set of Rust-based forensic tools), Thanatology combines performance, transparency, and modern design via a Tauri-based desktop interface. Designed for law enforcement and digital forensic professionals, the project emphasizes not only artifact collection and presentation but will also try to provide help for interpretation.

For example, when analyzing EXTFS file systems, Thanatology will try to offers guidance on timestamp meanings and includes complete extraction details suitable for annexing to formal reports.

The blog series will cover:

  • An overview of the Thanatology project and its goals.
  • A high-level introduction to the Exhume tool suite.
  • Deep dives into each Exhume module and its specific forensic use case.
  • Updates on the project development.
  • Interesting research techniques we found during our journey.

While Thanatology is not intended to replace established tools, it will attempt to offers a modular and modern alternative ideal for cross-verifying findings or integrating into custom workflows. This blogpost series is mainly here to provide the community with updates, technical knowledge and any interesting subjects we found along the way.
