It's the little things (Part One)

February 1, 2010

For forensic analysts working in Windows environments, .lnk shortcut files and the thumbprint caches are valuable sources for details about missing data.

Individuals wanting to hide their activities may flush their browser cache, Temp files, use, and even wipe the drive free space. However, they may forget these two minor "tidbits". These can show detail, indicate actions and associated history. Be Warned, I have found Windows machines having thousands of .lnk files on a "scrubbed PC."

The shortcut (.lnk) file is an amazing mine of information for such a small file. This PDF (See Link) is an invaluable source describing the details of the shortcut .lnk. The shortcut file name format is usually name.ext.lnk There may be multiple .lnk files created for one file depending upon the type.

XP stores the .lnk files for the Word 2007 Document Brains.docx in:

%Drive%:\Documents and Settings\User ID\Recent

The above .lnk (..\Recent)is slightly larger

%Drive%:\Documents and Settings\User ID\Application Data\Microsoft\Office\Recent

Windows 7 stores these .lnk files in

%Drive%:\Users\sdd\AppData\Roaming\Microsoft\Windows\Recent

The above .lnk (..\Recent) is twice the size of the second.

%Drive%:\Users\sdd\AppData\Roaming\Microsoft\Office\Recent

.lnk File properties show only a tip of available information. Compare the same Word 2007 Brains.docx.lnk file for XP and Windows 7. I use XVI32 as my hex-editor for details about the type of storage, location, Volume Serial number and much more.

Review the XP Hex dump example below. Then, compare the two different hex dumps of Windows 7 .lnk files. (You may need to zoom to inspect the images.) I did not include all of the first .lnk file hex.

Thumbs or Thumbnails are also invaluable source of data. I will discuss them in my next posting. I will then tie the Thumbnails and Shortcuts together.
