Forensics Analysis of Pagefile, hibersys File

In forensic investigation, Memory dump, pagefile and hiberfil files can provide us a lot of data. Memory dump is the file which contains the   information about the cause of the system crash.
Pagefile.sys: Microsoft Windows uses a paging file, called pagefile.sys, to store frames of memory that do not current fit into physical memory. Although Windows supports up to 16 paging files, in practice normally only one is used.

Hiberfil.sys: hiberfil file stores the data when Microsoft windows computer system is on Hibernate mode.
These files are very useful for digital investigation because these files are not stored in physical Hard Disk.

First of all download Access Data FTK Imager from here so to capture the memory dump, click on capture memory option.


A new window will pop up. Click on browse button to select destination path. Select the option Include Pagefile & click on Capture Memory.




After completion of process, two files will be carved in the specified folder.


To Extract the Hiberfil  file, click on add all attached devices


 Now click on the directory where windows are installed.  Select Root Folder and click on hiberfil.sys file.


Now right click on Hiberfil file & click on Export files.


Select the folder



After process completion, it will show the message about exported file


Now to analyze the Live RAM image file, we will use Belkasoft Evidence Center.

Now open Belkasoft Evidence Center.  Click on New Option. Click ok.


Enter all the details as well as root folder. 


Now select the option Live RAM Image.


Now select the specified path to mount an image file. In File Name option select All Files (*) It will show the files.  Select Pagefile .sys.


Now select the option Analyze Data Source click on Next.


 To select the supported data types to curve, Click on Select All option and click on Finish.


To analyze visited URL. Click on Chrome Live Ram


Similarly Click on Opera Live Ram.


Click on Found Pictures to see the images.


Same method use for hibersys file

Step by Step Tutorial of FTK Imager

FTK® Imager is a data preview and imaging tool that lets you quickly assess electronic evidence to determine if further analysis with a forensic tool such as Access Data® Forensic Toolkit® (FTK) is warranted. FTK Imager can also create perfect copies (forensic images) of computer data without making changes to the original evidence. With FTK Imager, you can:

·         Create forensic images of local hard drives, floppy diskettes, Zip disks, CDs, and DVDs, entire folders, or  individual files from various places within the media.
·         Preview files and folders on local hard drives, network drives, floppy diskettes, Zip disks, CDs, and DVDs
·         Preview the contents of forensic images stored on the local machine or on a network drive
·         Mount an image for a read-only view that leverages Windows Explorer to see the content of the image exactly as the user saw it on the original drive

·         Export files and folders from forensic images.
·         See and recover files that have been deleted from the Recycle Bin, but have not yet been overwritten on  the drive.
·         Create hashes of files using either of the two hash functions available in FTK Imager: Message Digest 5 (MD5) and Secure Hash Algorithm (SHA-1)

First Download FTK Imager From here and install in your pc.

ADD Evidence Item

Click on Add Evidence Item to add evidence from disk, image file or folder.


Now select the source evidence type as physical drive, logical drive or image file. We have selected image file and click on next.


Select virtual drive image & click on open option.


Select the source path and click on finish.


Now select Evidence Tree and analyze the virtual disk as physical disk.


Similarly to add raw image select again add evidence item and click on image file and click on open option.


Click on finish.


Now raw image will be added as physical drive to analyze.


Mounting an Image as a Local Drive

To mount an image file, click on Image Mounting option.


Select virtual drive image.


Select Mount Type, Drive Letter and Mount Method and click on mount option.


Now it will show the virtual drive.


Now select the image file to mount image to drive.



Capture Memory

Click on button “Capture Memory” how the picture below:


On the next window choice the directory to storage the extracted files, and click on the button “Capture Memory


Wait for the process finish.


A memory dump file will be created on the source directory.


Create RAW Image

Now open the FTK Imager and Click on Create Disk Image


Now a “Select source” box will open and choose “Physical Drive” click NEXT  


Now choose the drive of the Suspect Evidence you want to make image.


After choosing the Drive Click on finish to Start Creating Image of Suspect Evidence

(Note: choose option “Verify images after they are created”)


Now in Select Image Type Choose “Raw (dd)” and click on NEXT


Now In” Evidence Item Information” Fill the Following attributes, as you can see some random information given can be random as per the Suspects Evidence. Click NEXT


Now choose the location of the image you want to create and Name the Image Filename. And click on FINISH


Now in final Step Click START button to start Creating Image.


Successfully the Suspects Evidence Image Is Created .Now you can audit the Suspects evidence from the image Created from FTK Image.

Forensic Investigation of RAW Image using Forensics Explorer (Part 1)

Forensic Explorer is a tool for the analysis of electronic evidence. Primary users of this software are law enforcement, corporate investigations agencies and law firms. Forensic Explorer has the features you expect from the very latest in forensic software. Inclusive with Mount Image Pro, Forensic Explorer will quickly become an important part of your forensic software toolkit.

It enables investigators to:

·         Manage the analysis of large volumes of information from multiple sources in a case file structure;
·         Access and examine all available data, including hidden and system files, deleted files, file and disk slack and unallocated clusters;
·         Automate complex investigation tasks;
·         Produce detailed reports; and,
·         Provide non forensic investigators a platform to easily review evidence.

Supported File Formats

Forensics Explorer supports the analysis of the following file formats:

·         Apple DMG
·         DD or RAW;
·         EnCase® (.E01, .L01, Ex01);
·         Forensic File Format .AFF
·         FTK® (.E01, .AD1 formats);
·         ISO (CD and DVD image files);
·         Microsoft VHD
·         NUIX File Safe MFS01
·         ProDiscover®
·         SMART®
·         VMWare®
·         XWays E01 and CTR


First Download Forensics Explorer From here and install in your pc. And Click on New Option


Enter the Case Name and click on new option in Investigator TAB


Here in next step you have to enter the FULL NAME, TITLE, and Organization, Department and email details and click on ok to proceed to next step.


Select the cases folder where Forensic Evidence will be created. And click on ok

Now Select tasks to be processed on RAW image   from given list and click on Start.


After Process completion, it will show Result for all the tasks selected earlier.


Now Click on File System. The File System module is the primary Forensic Explorer window where actions such as highlighting, selecting, sorting, filtering, flagging, exporting and opening occur.


 Select Registry analysis: Open and examine Windows registry hives. Filter, categorize and keyword search registry keys. Automate registry analysis with RegEx scripts.


Bookmark selection enables almost any item (e.g. file, folder, keyword, search hit, etc.), or a selection from an item (e.g. a fragment of text from a file or unallocated clusters), to be bookmarked and listed in the Bookmarks module. 


Reports: The purpose of the Reports Module is to assist in the generation of a report that documents the forensic analysis. The Reports module is based on the use of templates that can be re-used across multiple investigations.
