Daily Blog #568: Solution Saturday 12/15/18

Hello Reader,
This week I changed up the challenge and you stepped up to the task. This week the master of DFIR knowledge summarization used his skills to pull of a win by one project. Congratulations to Phill Moore (and his baby) for this weeks win!



The Challenge:
Find all the projects out there that are making use of DFVFS (https://github.com/log2timeline/dfvfs) with a description of what the code does with it. Let's see if we can find all the possible exemplar code bases out there to help others adopt this framework!

The Winning Answer:

dfVFS, or Digital Forensics Virtual File System, provides read-only access to
file-system objects from various storage media types and file formats.
The goal of dfVFS is to provide a generic interface for accessing file-system
objects, for which it uses several back-ends that provide the actual
implementation of the various storage media types, volume systems and file
systems.


Log2timeline is a tool designed to extract timestamps from various files found on a typical computer system(s) and aggregate them. Plaso documentation
A DFVFS backed viewer project with a WxPython GUI for viewing file systems and file system metadata. Forensic Lunch about it

Allows you to extract a file from forensic images, virtual disks, raw images and live disks, including from volume shadows. Blog posts:
An open source tool set built on dfVFS. Blog post about it

Evidence Fetcher (efetch) is a web-based file explorer, viewer, and analyzer. Efetch supports viewing hundreds of file types including office, registry, PST, image, and SQLite files. Efetch supports navigating RAW, E01, ZIP, GZ, TAR, VMDK, VHD, QCOW, and BZ2 files thanks to dfVFS.
Blog post about it

A tool for when you have a bunch of documents to figure out of. Gransk is an open source tool that aims to be a Swiss army knife of document processing and analysis. Its primary objective is to quikly provide users with insight to their documents during investigations. It includes a processing engine written in Python and a web interface. Under the hood it uses Apache Tika for content extraction, Elasticsearch for data indexing, and dfVFS to unpack disk images.

A Python implementation of VMPOP (Virtual Machine POPulation) framework. dfVFS is used to enable for Data Extraction features

ArtifactExtractor is a script that extracts common Windows artifacts from source images and VSCs.

This program automatically finds provenance related to a file on an image
I’m not exactly sure what that means.

Technically doesn’t use DFVFS, but a long time ago Dave put out a Sunday Funday challenge to automate the installation so I wrote this script. It may not work any more, it worked at the time.

    If you need an easy way to install dfVFS look at the plaso documentation for l2tdevtools use preset dfVFS instead of plaso. I:ll make a note to add some up to date docs after the upcoming plaso release.
