X-Ways X-Tension C4All users-CETS & pic/vid library option

Post Posted: Tue Jun 10, 2014 10:07 am

C4All is a program used by law enforcement and others to categorize pictures and videos.

This X-Tension is for Users of C4All. The guides that are included describe how to best use the X-Tension with the Strategy hash sets , but your own hash sets can be used. Also it is based on the file types (video and pictures) that C4All presently uses and searches for.

With this X-Tension, you will be able to process with the speed of X-Ways, and be completing most of the C4Prep stage all at once (like skin tone % and video stills).

Benefits of the X-Tension
-speed, fewer steps to follow than original C4All process
-even faster if ran locally and saved locally. upto 30GB min speeds on SSD drives observed.
-crash protection. Use X-Ways ability to resume if there is a crash during preparation of data.
-If X-Tension is interrupted there is the option to resume, start new or if needed just make new XML file
-ability to filter out irrelevant files and false positive carved files before C4All extraction.
-Hash sets are connected to X-Ways and not SQL server. This allows for known irrelevant or good files to be excluded from extraction. Also SQL Express can be used (free) as the only database used would be a local database and would not grow to be to large.
-These hash sets are transferable by simply copying the folder and pointing X-Ways to storage location. No need to wait all day for Database to be created.
-ability to use your own hash sets. upto 65,000+ separate hash sets.
-Better resulting folder structure, especially when run against many evidence objects in one case.
-Results can be extracted from C4All in hashkeeper format to be easily brought back in to X-Ways case. no need to run Encase book marking enscript.
-thumbnails are extracted from files that include thumbnails or are created by X-ways due to original picture size. If thumbnails exist in a file it is not used twice, reducing duplicate files.
-When processing, all functions of X-Ways are available during X-Tension run phase.
-Able to use X-Ways reporting features for court and presentation.
- video stills extracted using free mplayer or forensic framer from within X-Ways

Below are links to the X-Tension and guides on how to use it. If you are part of the Strategy and need the hash set, please contact Trevor at the Ontario Provincial Police or obtain from the C4All forum.
In the guides there is also information on how to use your own hash sets and including extracting them from your SQL server.

Update October 19 2014
download link to version 3.6.2.c 1drv.ms/1prWU2h
-Fixed issue with extended character support of UTF-16 in XML. should show all but those 0xD800 – 0xDFFF characters.
-Adds the functions of 3.5.12.k as well as option to create a Picture/video library based on MD5 hash value as name and the option to include not confirmed files when extracting pictures and movies. (before the file had to have a type status of Confirmed or newly identified. see post from 27 September in this thread for more details)
- 3.5.12.k
option to include or not include metadata in XML
-The option to run against multiple evidence objects and better naming of folders in c4all folder tree.

Excellent OPP software - I am pleased to say that Reconnoitre has worked with C4ALL for about 18 months now (including the ability to easily resolve a graphic carved in a VSC back to the actual file within the VSC).

Thanks goes to Dennis for creating a C4All category for use with the "File Type Signature Search.txt' file.
Just append the contents of the linked file to the 'File Type Signature Search.txt' file in the X-Ways install directory and a new category to select all the C4All files in one click has been added.

Download link to 'c4all category for file header signature search.txt' 1drv.ms/1q9bMa6

A separate file based on Dennis' C4All category for File type signature searching. copy this file to the install directory of X-Ways. 1drv.ms/TZ8Grl
This file does not get overwritten during updates and works the same, allowing one click to select all relevant C4All file types.

MD5 hash file manipulator to be used with C4All X-Tension
www.forensicfocus.com/...c/t=12040/

This will help maintain your hash sets as well as removing duplicates or records that are wrong hash set.
