Test Images and Forensic Challenges
Computer Forensic Reference Data Sets (CFReDS)
The CFReDS site is a repository of reference sets/images of simulated digital evidence for examination. Some images are produced by NIST, often from the CFTT (tool testing) project, and some are contributed by other organizations.
A website of digital corpora for use in computer forensics research. Some of the corpora on this website are freely available, while others are only available to researchers under special arrangement.
Digital Forensics Tool Testing Images
File system and disk images from Brian Carrier for testing digital forensic analysis and acquisition tools.
This site is intended to assist members of the computer forensic community learn more about Linux and its potential as a forensic tool. Various practice images are available under the heading "Supplemental Files" in the left hand side menu.
