2. Windows 7 Jump Lists
• . . . users should be able to “jump” directly to those things they want to work with and start
working with them in a single mouse click. To provide this functionality, Windows 7 Taskbar
introduces the concept of “Jump Lists.”
• . . . think of Jump Lists as your own mini Start Menu for your application.

3. Windows 7 Jump Lists
Ramifications for forensic investigations:
– History of items opened or modified by a particular application.
• Similar to other Most Recently Used (MRU) or Most Frequently Used (MFU) artifacts.
• But not based on shortcut (.LNK) files or registry stores.
– Distinctive features:
• Lists of MRU or MFU items organized by application.
• List can retain several hundred items.
• Items may remain on a list after their target is deleted from the volume.
• Although items can be deleted from the lists, deletions can be detected.
• Only a few items shown for any list; list can have hundreds more items than are shown.

4. Windows 7 Jump Lists
Jump Lists are likely to be worth investigating in detail, when:
– A user’s historic activity is at issue.
• What files, SharePoint sites, or Web pages have been opened or accessed.
– There is a concern that data files have been deleted or moved.
– To show knowledge or intent.
– Search term hits occur within Jump List files.

Jump List content is derived
from two data files.
– “Destination” files.
• [AppID]automaticDestinations-ms
• [AppID]customDestinations-ms

8. Windows 7 Jump Lists
• Automatic Destinations:
– List of “destinations.”
– Automatically populated by the system.
– Based on calls to SHAddToRecentDocs.
• Collects information about data file usage.
• Records information in the Recent Items folder, and the “using” application’s automatic destination
file.
• Sorted by recency (MRU) or frequency (MFU).
C:Users[Profile]AppDataRoamingMicrosoftWindowsRecentAutomaticDestinations
• Custom Destinations:
– List of “destinations.”
– Content maintained by the application.
• Custom categories.
• Tasks specific to the application.
– Specified by the application using the ICustomDestinationList API.

Note:
– More automatic destination files.
– Matched pairs share the same AppID
– Custom destinations have temporary files.
And so on.

13. Windows 7 Jump Lists
• AppID is based on the process name or can be
specified by the application.
– Different command arguments for the same
application may result in different AppIDs.
• Applications can have more than one AppID.
– The same process (with same command argument)
should have the same AppID across systems.
• AppID can be used to identify the application owning a
destination file.
• Permits the investigator to selectively investigate destination
files.

Analysis of Custom Destination Files
• Review the series of shell link
items in a hex editor.
Or
• Carve and parse:
– Using a hex editor, carve out each
shell link item, saving each to a
separate file.
– Use a link file parser to review the
extracted shell link streams.
– Some streams may not be complete
shell items, e.g. paths.
Analysis of Automatic Destination Files
• Parse the file with a structured
storage viewer and review the 1)
stream enumeration and 2) shell
link streams.
Or
• Carve and parse:
– Using structured storage parser/viewer,
extract each stream to a separate file.
– Review the DestLisk with a hex editor.
– Use a link file parser to review the
extracted shell link streams.
