DIGITAL FORENSICS: Booting a forensics image on a Virtual Machine

Starting with V9. of OSForensics, booting a forensic image of a system disk as a virtual machine has never been easier.

When performing forensic investigation on an image of a target system drive, it is often necessary to recreate and examine the live environment of the system to acquire all relevant data during the investigation. By running the image as a live system, the investigator can perform a live forensic analysis of the image, allowing for the potential discovery of additional forensic artifacts that may not have been previously uncovered from a traditional static analysis. Finally, because the system is running in a protected virtual environment created from the forensic image file, there is no risk of compromising the target system.

In addition to being able to review the Desktop layout, the Recycle Bin, and proprietary files in their native application, this also provides a great visual aid for screenshotting evidence to present to a client or in court when necessary.
