Forensic analysis of VMware on Linux – Investigating VMware virtualisation environments on Linux

VMware products such as VMware ESXi and VMware Workstation are also used on Linux hosts and for virtualising Linux guest systems, utilising proprietary, well-documented file formats for virtual hard disks and snapshots.

The forensic analysis takes into account both the configuration of the virtual machine and any snapshot chains it contains, which can provide a traceable record of previous system states.

Why LanCologne?

Since its foundation, LanCologne has specialised in professional IT forensics. Our staff have decades of experience in the field of information technology and assist companies, solicitors, private individuals and, on a regular basis, the courts in the technical investigation of complex digital matters.

The examination is, as a matter of principle, carried out exclusively on a forensic copy, a forensic image or a data source captured in a technically equivalent manner that preserves the integrity of the evidence. The original evidence remains unchanged and is stored in a manner that preserves its integrity.

Our services

We back up and analyse VMware configuration files, virtual hard disk images and snapshot chains, and, where necessary, carry out a full investigation of the virtual Linux systems they contain.

Typical areas of application

Forensic backup and analysis of VMware-based virtual machines
Analysis of snapshot chains to reconstruct historical states
Investigation of compromised virtualisation environments
Analysis of VMware log files
Incident Response on Linux Systems
Judicial and non-judicial expert reports

How a VMware analysis works

Once the virtual hard disk images, configuration files and snapshot information have been backed up, they are mounted for forensic analysis and evaluated. Snapshot chains are analysed for previous system states and compared with the current state.

Why is the VMware analysis relevant from a forensic perspective?

VMware environments are frequently used in business-critical infrastructures, which is why a robust forensic investigation of such virtual Linux systems can be of significant economic importance.

Where available, snapshot chains can enable a particularly detailed reconstruction of events over time, as they document several successive system states.

Frequently Asked Questions

Which VMware products are relevant to Linux forensics?+
In particular, VMware ESXi as a Server hypervisor and VMware Workstation for desktop virtualisation, both of which use comparable file formats.
Can deleted snapshots be recovered?+
In some cases, provided that any associated residual data or log entries are still available.
Is it possible to carry out a forensic analysis without interrupting ongoing operations?+
In many cases, yes – for example, by taking a snapshot whilst the system is still running.
