[How to] Create and verify a mutli-part disk image with FTK Imager
This video shows how to make a disk image using FTK Imager on a Windows system.
FTK Imager is an easy to use tool for copying data from suspect disks, and has other functions such as verification features and a hex view. It is a simple, stable tool that is a useful part of the beginning of an investigation.

[CFP] CLOUDFOR extended submission deadline
CLOUDFOR 2016: Workshop on Cloud Forensics
In conjunction with the 9th IEEE/ACM International Conference on Utility and Cloud Computing (UCC), Tongji University, Shanghai, China.
6-9 December 2016
Scope and Purpose
=================
As a consequence of the sharp growth in the Cloud Computing market share, we can expect an increasing trend in illegal activities involving clouds, and the reliance on data stored in the clouds for legal proceedings. This reality poses many challenges related to digital forensic investigations, incident response and eDiscovery, calling for a rethink in traditional practices, methods and tools which have to be adapted to this new context.
This workshop aims to bring researchers and practitioners together as a multi-disciplinary forum for discussion and dissemination of ideas towards advancing the field of Cloud Forensics.
Topics of interest comprise, but are not limited to:
* Digital evidence search and seizure in the cloud
* Forensics soundness and the cloud
* Cybercrime investigation in the cloud
* Incident handling in the cloud
* eDiscovery in the cloud
* Investigative methodologies for the cloud
* Forensics readiness in the cloud
* Challenges of cloud forensics
* Legal aspect of cloud investigations
* Tools and practices in cloud forensics
* Case studies related to cloud forensics
* Forensics-as-a-Service
* Criminal profiling and reconstruction in the cloud
* Data provenance in the cloud
* Law enforcement and the cloud
* Big data implications of cloud forensics
* Economics of cloud forensics
* Current and future trends in cloud forensics
* Grid forensics
Important dates
===============
* Paper submission: 15 August 2016 (extended deadline)
* Notification of acceptance: 05 September 2016
* Camera-ready submission: 21 September 2016

Submission
==========
Authors are invited to submit original, unpublished work which will be reviewed by three committee members. Submission should be blind, i.e., with no stated authors, or self-references. Papers should comply with the IEEE format, and have a maximum of 6 pages; guidelines are available at: http://www.ieee.org/conferences_events/conferences/publishing/templates.html
All accepted papers will be published in the IEEE conference proceedings – provided they are presented at the workshop.
Submission will be handled through EasyChair: https://easychair.org/conferences/?conf=cloudfor2016
Facebook Capture the Flag Platform Now Available
Facebook’s hacking education platform and capture the flag is now available. See their release single here. Their goal is to educate about different types of web attacks by giving access to CTF infrastructure and letting more groups run hacking competitions. From their github repository:

[How-to] Load a multi-part disk image into FTK Imager
When working with multi-part disk images, it can be confusing to see if your tool has loaded all of the image or just a part. Below is one way to determine if all of your disk image has been loaded, or only the first part in FTK Imager.
<div class="separator" style="clear: both; text-align: center;"><div class='embed-container'><iframe src='https://www.youtube.com/embed//bW7BBcbl_Vc' frameborder='0' allowfullscreen></iframe></div></div>
<h3>Verifying your disk image</h3>When working with your disk image, verification of the data should always be included in your workflow. In the case of a multi-part image, we should have at least two hashes:
<ul><li>A hash for the total disk image</li><li>A hash for each part of the disk image</li></ul><div>This is especially true for raw disk images, since they have no built-in checksum like expert witness format.</div><div>
</div><div>A hash for the total disk image is normally created by your acquisition tool, and can be found in the acquisition report. FTK Imager does not create a hash for each part of a multi-part image.</div><div>
</div><div>In this case, we may need to generate our own hashes using FTK, or another tool.</div><h4>Why do I need hashes for each part?</h4><div>If you have a hash value for the overall disk image, then - in terms of court - you will be able to show that the suspect data has not changed from the time that the disk was first acquired. However, having hashes of each part of the image can help in one major way.</div><div>
</div><div>The Expert Witness Format that EnCase uses has checksums every 32KB that enables verification of parts of a disk image. If one part of a disk image changes, we can potentially still use the other parts of the image that can be verified with their checksum, even if the overall hash can not be verified.</div><div>
</div><div>With a multi-part RAW image, we can get similar functionality by hashing each part. Each part can then be verified, along with the overall hash. If the overall hash is not valid, hashes of each part can be used to determine what part has changed. Other parts that can be verified may still be used.</div><h3>Loading a multi-part image</h3><div>When many tools load a multi-part image, they may only show the filename of the first part of the image. If the tool is made ‘for forensics’, then the tool will likely load the entire image under the first filename. In this case, verify that the tool can:</div><div><ol><li>Detect the full size of the original disk image</li><li>Can generate the correct hash value for the original image</li></ol></div>
