How to Using Vinetto

How to Using Vinetto 0.06 (r56)
This is part of the Digital Forensics section of BT2 and 3
Note: If using BT3 and this tool doesn't work then please see the thread here: [url=]Possible bug[/url]

Some Background: Vinetto is a forensics tool to examine Thumbs.db files.It is a command line python script that works on Linux, Mac OS X and Cygwin(win32).
Source: [url=]Vinetto[/url]

If you do something that causes you to hose your box don't come kicking and screaming on the forums!

OK you may be asking your self "why would I need this tool?" This tool and the whole "forensics section" of BT is one that the average person is not going to use. Now on the other hand if you conduct forensics investigation as either some type of "police official" or as a pen tester, then this tool can come in very handy for you.
Now there are other tools that can do the same basic thing however if you need it it's included.

NOTE: When doing any type of forensic work it is imperative that we do not damage the target computer in any way. Having said that we should boot our BT disk over our target computer using the "bt nohd" boot option. If you don't know what this means then stop here and go read about it here: [url=]Cheats[/url]

Ok in order to get this to work we need to go to the command line or alternatively through K>Backtrack>Digital Forensics>All>Vinetto
Now lets have a look at the options that are presented when we do a --help
[code] bt ~ # vinetto --help
usage: vinetto [OPTIONS] [-o DIR] file

--version show program's version number and exit
-h, --help show this help message and exit
-o DIR write thumbnails to DIR
-H write html report to DIR [/code]

Now the output shows us only two useful switches -o will write our thumbnail to a given directory and the -H creates a html report to a directory
and these two can be combined like so -Ho this will give us both the thumbs and and report in html format. This is useful if we have a lot of thumbs to go through.
So far so good right? OK now for my example usage.

I booted BT over my laptop that has Windblows XP next I opened a shell and did a:
[code]# find / -name Thumbs.db
/mnt/hda1/Program Files/Windows NT/Thumbs.db
/mnt/hda1/Program Files/Microsoft Office Old/Office/Bitmaps/Dbwiz/Thumbs.db
bt ~ #
The above is a truncated version of the output, yours will be different. Our target file will be the last one, the "/Dbwiz/Thumbs.db"
So now you need to setup a storage device of some sort I used a usb stick seems to be the easiest. now go ahead and mount it and make a directory in it.
I used "thumbs" for mine. Ok now we have both a target directory and a "save location" we can go ahead and extract our thumbs to it.
so in a shell again give:
[code vinetto -Ho /mnt/sda1_removable/thumbs "/mnt/hda1/Program Files/Microsoft Office Old/Office/Bitmaps/Dbwiz/Thumbs.db"

** Warning: Cannot find "Image" module.
Vinetto will only extract Type 2 thumbnails.

7 Type 2 thumbnails extracted to /mnt/sda1_removable/thumbs/
[/code] hit enter and you should see the same basic output as above.
This show use the thumbs that we have recovered and the time they were created on our target and as well as their respective names.
Now we can go to our "save location" to verify our files are there. Also check out the .html output file as this is easier to manage then all of the other files.
I have posted some photos of the output if you need look at them [url=]VinettoOutput[/url]

And that's it, a simple program that can help if you need it.
Please leave some feedback if this helped or hindered you, Thanks :)

This is where I got most of the information from as well as the vinetto website.
I did find in my experiments that you need to use the flags as "-Ho" and not "-oH" doing so I got a "vinetto: error: incorrect number of arguments" error each time.
