– Windows 10 jump lists forensics free
Creation of these LNK files were expected since those items were accessed to accept data. However, since this textbook was published in , it predated the release of the Windows 10 operating system. Opened grandparent folder Expenses Opened parent folder Software Copied file without opening the file. For the original location, the target file created and modified timestamps remain unchanged while the target file size was recorded. Jump Lists are also user specific and are valuable to forensic analysts to identify user file activity. Jump List Forensics. The author will not be liable for any special, incidental, consequential or indirect damages due to loss of data or any other reason.
Forensic question: Are link file and jump list artifacts changed for Windows 10? Windows users can create shortcut files on the systems they use. Shortcut files are most often referred to as Link files by forensic analysts based on their. In addition to user created LNK files, the Windows windows 10 jump lists forensics free system automatically windows 10 jump lists forensics free LNK files when a user qindows a non-executable file or document.
Windows creates these LNK files on a frequent basis and their creation is performed in the background without the explicit knowledge of the user. Some of these pieces windows 10 jump lists forensics free information include:. The Attributes associated with the target file i. The forensic name, volume name, volume serial number, and sometimes the MAC address of the system where the target is stored. A USB investigation to identify files opened from a specific removable USB device but never saved locally to the system.
The user knowledge of specific files opened whether those files were stored on the local system, attached removable devices, or network storage. The identification of files which wondows longer exist on a local machine. While a deleted file which was previously opened generating a LNK file on the system no longer exists, the system may retain the LNK file recorded to access the deleted file.
Jump Lists were windows 10 jump lists forensics free with the release of Windows 7. Jump Lists are software application specific in that they record files opened from a specific software application. To access a Jump List, the user would right-click the windows 10 jump lists forensics free application from the task bar i. Automatic Windows 10 jump lists forensics free contain features which are common across all software applications.
Automatic Destinations contain the file extension. Automatic Destinations are compound files which contain multiple data streams within the single file.
Dindows Automatic Destinations, each stream contains an embedded LNK entry which can be extracted and windows 10 jump lists forensics free. Custom Destinations have the file extension. Custom Destinations can also contain a series of LNK entries for files opened using the software application 13Cubed All that is required of the forensic analyst is to determine the software application associated with a Jump List AppID.
Jump Lists are fkrensics user specific and are valuable to forensic analysts to identify user file activity. Serial number sony cinescore free download Destinations are stored in the wkndows AutomaticDestinations cs go free download for pc with multiplayer смотреть!! Custom Destinations are stored in the sub-folder CustomDestinations.
When a user opened a file such as MyDoc. Forensic analysts could use these two Windows generated artifacts to document user file activity. This limitation only effected older LNK files since they were removed from the /15750.txt folder once the maximum file limitation was reached. In some of my recent digital forensic investigations involving user file activity, my investigations have focused on systems where the Windows 10 operating system was installed.
As previously stated, the analysis of LNK files and Jump List entries on Windows 7 systems produced very similar results. My recent Windows 10 investigations windows 10 jump lists forensics free user file activity were beginning to identify a higher number of Jump List entries when compared to the LNK files found on the system. Analysis matched the active LNK files on the system with corresponding entries within the various Jump Lists; however, Jump List entries were present where there was not a corresponding LNK file, and the timestamps for the Jump List entries post-dated the timestamps of the LNK files.
Four commonalities were identified in the Jump List entries where there was no corresponding LNK file:. Almost fred, the Windows Explorer Jump List entries identified folders and not files; and. Jump List entries were identified for windows 10 jump lists forensics free AppID previously not seen — 5f7b5f1e01b I consulted several previously published papers concerning the forensic value of LNK files and Jump Lists.
Several of the sources used in my research were informative and described in detail the structure of Jump Lists and LNK files; nump, some of these papers predated the release of the Windows windows 10 jump lists forensics free operating system. However, since this textbook was published init predated the release of the Windows 10 operating system.
First, when a file is createda LNK file for that target file will also be created. Secondly, when a target file was created windows 10 jump lists forensics free, a LNK file would be created for the folder and parent folder where the created target file was created. While the SANS FOR textbook expanded the definition and behavior of Windows 10 LNK files, it was not clear whether created files referred to just newly created files, files copied from one volume to another, or files moved from one volume to another.
Нажмите для продолжения no further explanation was windows 10 jump lists forensics free, this reference to Jump Lists as a potential source of user file activity expanded to include created files. A Lexar USB thumb drive was used as the removable device. The three devices would be used during the testing process to create, copy, and move various files and folders. The testing was split into five different sessions with each session having a different testing objective based on the user file and folder activity performed during the session.
The following analysis steps were performed during each testing session:. Session One focused on windows 10 jump lists forensics free copying and moving of individual files and folders from one device to another. Session Two focused on the simultaneous copying and moving of multiple files and folders from one device to another. Session Three focused on the opening of existing files from one device, and then saving the opened file to a different device using a different file name.
Session Four focused on the creation of individual files on each of the devices. Session Five copied and windows 10 jump lists forensics free Microsoft Office files without opening any of the copied or renamed files. Session One testing included the user activity of copying or moving individual files or individual folders between the three devices. On February 5,the following user file and folder activity windows 10 jump lists forensics free place:. When individual folders were copied from one device to another without first opening the folder.
When individual files were copied from one device to another without first opening the file. User activity for Session One included the opening of a previously established file, and then that file was saved to another device location using the Save As feature of the software application used to open the previously established file.
It was interesting to note that the LNK files were created for the newly saved file location, but not for the original file location. This LNK file behavior for the newly saved file was anticipated since the newly saved file was also open within the software application at dree time it was saved.
What was not anticipated was the absence of a LNK file for the original file opened from the original location. An inconsistency was noted in the LNK file behavior for folders opened to access files within those folders. This folder was opened initially to access the file Monthly Mileage Report.
To summarize the Jump List analysis for Session One:. Windows Explorer Windows 10 jump lists forensics free List entries were created for the destination folder when a single folder was copied from the original device to a new device. This behavior of creating Windows Explorer Jump List entries for a single copied folder is the first identified user activity in Windows 10 not previously recorded in prior operating system versions.
These Dindows List entries for opened single folders documented additional detail not provided by LNK files. The Microsoft Word Jump List entries also record the target file size for both files. The Quick Access 1 Jump List entries were consistently created each time a file was saved to a new device location, and most often created when the original file was opened from its original location.
When a Quick Access Jump List entry was created from the original file location, the Last Access timestamp of the target file was updated and the target file size was recorded. Quick Access Jump List entries for the newly saved file location перейти different data based on the file type:. For Microsoft Word files, the target file created timestamp, modified timestamp, and the target file size were not recorded.
For text Notepad file types, the target file timestamps and the target file size were recorded. Notepad Jump List entries were created for both the original file location and the newly saved device location, but each entry recorded differing data.
For the originally opened TD2ServerTest. For the newly saved TD2ServerTest. Individual files were copied from one device to another without first opening the file. Session Two testing focused on the forenaics activity of simultaneously copying or moving multiple files or folders between the three devices.
On February 8,the forejsics user activity was performed:. Creation of these LNK files were expected since those items were accessed to accept data. Windows 10 did not create LNK Files for any of the following user activities:. In summary. Windows Explorer Ofrensics List entries were created for the destination folder locations when the user simultaneously copied multiple folders from one frfe location to another. It was noted that while the simultaneous copying of multiple folders created Jump List entries, the simultaneous copying of files did not produce Jump List entries.
Session Three testing involved opening a previously saved file using its default software application windows 10 jump lists forensics free then saving the file with a different file name on a different device.
Some of the opened and renamed files were edited while some were saved un-edited in their original data form. On April 15,the following user actions were taken:. In each instance of user file activity performed in Session Three, Windows created or updated listts LNK file for both the original file location and for the new saved file location.
This windows 10 jump lists forensics free was expected since the original file was opened and the newly saved file remained open after being saved in a new file location. In Session One, original files were opened and then saved to a different device location using the same filename. Session One testing identified LNK files created for the files saved in the new device location with no LNK files created or updated for the original file location.
Inconsistencies were observed from the data recorded within the Lisgs files created during Session Three. The Session Three LNK files were somewhat inconsistent in their recording of the target file created timestamp, the target file modified timestamp, and the target file size for newly created files. The target timestamps and target file sizes were recorded for the single newly created eindows file.
The target timestamps and target file size were recorded for the newly saved file April-Mileage. The target timestamps and target file sizes were not recorded for the newly saved files Interview. The cause for the inconsistent recording of data for Microsoft Word file types within the LNK files is unknown and may require more testing.
In the Session Three test, the analysis of LNK files and Jump List entries reflect those two artifacts report similar data for files which are opened and then saved using a different name on a different device. Depending on the 01 List, slight variations were observed in the data recorded by the Jump List.
A summary for each Jump List recording Session Three user file windods is detailed below:. The Foxit Reader Jump List was the most consistent in its behavior.
It recorded entries for both original file location as well as the newly saved location.
Jhala, A. Abstract The release of Microsoft Windows 7 introduceing a new interesting feature which known as Jump Lists that present the user with links to recently used or accessed files grouped on a application basis. Windows 7 Jump Lists are a new interesting artifacts of the system usage which may have some significant values during forensic analysis where users different activities are of interest.
In this paper, Section 2 gives an overview of actual backend information of the jump lists in the windows operating system. Section 3 is described the AppID of the diferent windows applications. Section 5 presents the forensically evaluation of the solution. These AppIDs can be set by the application or operating system at application runtime. When the application performs un certain actions, two types of files are genrated that are as below :.
When the user performs different uncertain actions like opening files, using the remote desktop connection tools etc. The Jump Lists Appear to be associated produced through file extension analysis. Calculates the Windows operating system the AppID of an application, knowing as an application’s AppID can help identify the identity of any given applications,when user activity is consist a special importance in an investigation.
The different files are named with 16 hexadecimal digits,. All experiments were conducted in a virtual environment, this was achieved by using virtual environment in VMWare Workstation 9. A virtual environment was created with two virtual disks attached with the file system that consist NTFS format, the first task to hold the OS and the second task to store a series of different specimen texts, pictures, musics and videos files.
Conducted experiments designed for a specific points with that a view to understanding the full architecture of the records maintained by windows operating system jump lists and were broken down into particular objectives. The virtualisation environment was used to capture a snippets at the completion of the installation and than after an account was created.
End of the process was allowed to complete by the newly created user logging on for the first time after that the virtual environment was shut down without accessing any files. All further experimentats was based upon counterfeit of the virtual environment where the password was applied to the user accounts and various tests were done to change the configuration of the different feature and update the records that maintained by it. The modification was achieved by accessing the customize start menu dialog box and that dialog box was resulted in the creation of the registry key value.
After the deselecting that particular option to store and display different afreshly seen items in the start menu. Further experiments identified that the data. In this either value is ‘0 ‘when the feature is disabled or ‘1’ when enabled. The next step was to use the regedit application of the windows operating systems to access the value of the registry and that is. None of these values were present at the time of first login.
The different functional areas of the different files and folder structures and the windows operating system registries that are generally used to store relevant data to the jump lists that has been created within a current user account at the point that account logs in first. When the system was configured as to showing the different hidden files and folders or not, the automatic destinations directory couldnt be seen when user attempt to navigate to hidden files through the windows explorer.
Once jump lists b4dd67f29cb When option is deselecting it is to store and display recently used or opened items in the start menu of windows operatin system. Navigate to the AutomaticDestinations directory and deleting the compound binary files from the windows explorer. A further entry entitled with DestList and it is also present and due to this element is structured, the little information is available relating to that the information contained within these jumplists elements.
A DestList Structure appeared as the first 8 bytes of an entry were kind of hash of the data. As to finding the following observations were made :. Any change occure in the data entry between the starting point of the unidentified 8 byte value before the data file path would result in any entries within the list after altered entry of data does not appearing in the jump list.
The jump list was rewritten to amend the file path to show the correct information once again. Describe number of add or delete actions Increments as entries are incleded. Most of the created jump lists are record the paths of the files to their respective target files in plain text with unique unicode encoding. The figure shows an encrypted view of windowsmedia file. Windows media player did not follow this trend but instead of this it uses a series of alphanumeric characters to document this information as shown in fig below:.
The link file of elements in windows media player also are different but in some point to the different executable itself with the different path of the target files recorded as a key during the execution of program. It has been noted windows media player that had recorded two entries for each and every file accessed. One stored with the file path as describe in figure and the other one with the full path. The respective file link elements replicated this with a point to the executable files and the other following the more convenient format with the different link associated files.
Not all applications that use all of the different fields that are available in a DestList entry. Below figure shows the difference between the amount of data recoded within the two different entries taken from the same DestList. When the target files are moved on different drives between the registered machines. For which have been moved files to a drive with the registered type removable such as USB devices any venture to re open a file subjected to such a deletion or move results in an error message is displayed on user screen.
The initial item was pinned to the start menu as a new sub directory that known as start menu is created within the path. That is used to store a shortcut files relating to that item. Unpinning from the start menu of taskbar results in the shortcut file being removed from the start menu sub directory. Record of these items were pointed to the taskbar is added to the data in the different values favorites and Favorites Resolve too.
Within the windows registry. The testing conducted showed that the overall number of items that pinned to the jump lists and that is recorded within the header of the DestList.
Pinning an entry to the jump list results in an update to 4 bytes in sequence in the DestLists and that record behave like a counter and changes from the default hexadecimal numeric value. That occurred as a results of pinning a single entry to jump lists are shown at below figure :.
Expanding of files of the jump list and manuall the entries are deleted by using the remove from this list option the following tasks were noted:. Whenever the last entry was removed from the list, entertained by the Jump List file was deleted from the AutomaticDestinations directory.
The task of removing an entry within the jump list may change the header of the DestList element as a depicted in figure below that provides the elaboration into the structure of that part of that particular element.
After the deselecting the option to store and display recently used as well as opened items in the start menu as well as the taskbar from the dialog box the was noted as follow :. All the files of Jump List contained no pinned that elements were removed from the automatic destinations directory.
Jump Lists for those that contain pinned items and all different entries were removed from that list and having only records that are relating to the pinned elements. The binary files of the jump lists can be fetched from the Automatic Destinations directory and running on a machine without changing the data that containing by them.
Jump Lists are newly introduced feature although windows operating system has been out for a while now some of the issues have already come up. Initial concurrence indicated that at least one jump list record may has been recovered from unallocated space of disk but it turned out that the different three problems of jump lists were from a live acquisition of an images and the applications in question could have been open on the system at a time of the acquisition.
This may represents an interesting valid problem that how do user deal with jump lists from live acquisition of images in the case of the apps were open during the acquisition? The answer is that user need to understand the binary structure of the jump lists because that is the only way to solve these types of issues.
When the tools are not working we need to either have the understand the formats to troubleshoot the issue ourself. From an analyst’s point of view Jump Lists are a newly introduced technology and artifact in the windows operating systems that need to be understood better. At this point we have considerable information which clearly indicates that these artifacts of windows operating system have value and should be parse in timelines for analysis. There are different ways for jump lists to containing analytic attributes similar to the registry and registry values and aso to prefetch files that bound specific user actions.
In addition the research area is necessary but that appears recently that jump lists also representing a persistent artifact which remains after deleted different files, folders and applications. This work was supported by eSF Labs Ltd, Hydreabad,India, that provided the technical conditions and the machines used for the development and testing of the solution.
Carvey, H. DOI : Kritarth Y. PDF Version View. Hyderabad , India A. Hyderabad , India Abstract The release of Microsoft Windows 7 introduceing a new interesting feature which known as Jump Lists that present the user with links to recently used or accessed files grouped on a application basis. Fig 1. Jump List example associated with MS Paint. As shown in Fig. Fig 2. Taskbar and Start Menu Properties Dialog box.
Fig 3. Customize Start Menu Dialog Box. Identifying the initial Jump List data. Modification in Config. Data present at first login. According to that different application was pinned and found in the windows registry value too. The windows registry value did not exist at this stage. Deleted date of Jump List.
As to finding the following observations were made : Any change occure in the data entry between the starting point of the unidentified 8 byte value before the data file path would result in any entries within the list after altered entry of data does not appearing in the jump list. The findings are supported that the entry which consist of first 8 bytes that is kind of hash. Some kind of counter.
Windows media player did not follow this trend but instead of this it uses a series of alphanumeric characters to document this information as shown in fig below: Fig. A programs are pin to the start menu or and. That occurred as a results of pinning a single entry to jump lists are shown at below figure : Fig. Expanding of files of the jump list and manuall the entries are deleted by using the remove from this list option the following tasks were noted: A pinned data or entry would not removed until it had been unpinned form the jump list.
Initial concurrence indicated that at least one jump list record may has been recovered from unallocated space of disk but it turned out that the different three problems of jump lists were from a live acquisition of an images and the applications in question could have been open on the system at a time of the acquisition This may represents an interesting valid problem that how do user deal with jump lists from live acquisition of images in the case of the apps were open during the acquisition?
