The code right next to 0 x 48 00 00 00 is 0 x 01 00. The Hex Value Interpreter converts this to 72 decimal. The 4 bytes behind 0 x 80 00 00 00 shows the length of the $DATA section. Notice the length of the $DATA section is 0 x 48 00 00 00. This will point directly to to the $DATA section of the specific MFT record. Go back to the magic marker FILE0 and use CTRL + F and do a Binary(hex) search for 80000000. One of the MFT attributes is the $DATA section.
Recover this picture for further analysis. The next 8 bytes show the File Read Time (UTC) The next 8 bytes show the MFT change time (UTC) The next 8 bytes show the file alternation time (UTC) In order to find byte offset 80, press CTRL + G (from current position).Īt byte offset 80 after the magic marker, select 8 bytes and the Hex Value Interpreter shows the creation time of the file is 14-12-2012 10:42:42 UTC. Carefully consider the options as this magic marker is some lines above the search hit.Īt byte offset 80 after the magic marker, shows the file creation time, which is 8 bytes in length. This JPEG file has more information, for instance each MFT record has a record header, FILE0, also known as magic marker. In this case, the search hit belongs to a file named IMG00264_20100109-1450.jpg. In a short while FTK Imager finds a result. Search for file artifacts in the MFT (FTK) Search for pictures and perhaps decide to enter the common term “IMG”.įigure 2. Click this file to show the contents in the Viewer Pane.Ĭlick the Viewer Pane and press the CTRL + F keys to open up the Find function. Click the root of the file system and several files are listed in the File List Pane, notice the MFT. The contents of the Physical Drive appear in the Evidence Tree Pane. Open the Physical Drive of my computer in FTK Imager. In this example I use FTK Imager 3.1.4.6 to find a picture (JPEG file) in Windows 7. We can use the MFT to investigate data and find detailed information about files. NTFS uses the Master File Table (MFT) as a database to keep track of files. This article describes, in a straightforward manner, the process of extracting NTFS file system data from a physical device.

How to recover file data with FTK Imager.How to locate file artifacts and metadata within the Master File Table.One of the most important tasks of a computer forensics expert is making file artifacts and metadata visible. The Master File Table or MFT can be considered one of the most important files in the NTFS file system, as it keeps records of all files in a volume, the physical location of the files on the drive and file metadata.
