Then type FF D8 FF EO, which are the correct hexadecimal value for the first 4 bytes of JPEG file. In the center pane, click to the left of the first 7A hexadecimal value. As mentioned, a standard JFIF JPEG file has a header value of FF D8 FF EO from offset 0 and the label name JFIF starting at offset 6. At the top of the Win Hex Window, notice that the hexadecimal values starting at the first byte position (offset 0) are 7A ZA ZA ZA, and the sixth position (offset 6) is also 7A. Navigate to your work folder, and then double-click Recover1.jpg.1 2. Start WinHex, and click File, Open from the Menu. If you can't next step is to examine the file's header data to see whether it matches the header in a good JPG file. Before attempting to edit a graphics file you have recovered, try to open it with an image viewer.

The next activity will guide and shows you how to rebuild header data from this recovered file by using WinHex. Header might give you additional search values that could minimize false-positive hits in subsequent searches. This unique header might give you additional search values that could minimize false-positive hits in As you can see in the result the file header has been overwritten with zzzz. In the Save As dialog box, navigate to your work folder, type Recover1.jpg for the file name, and then click Save. In the work area, right click the gametour4.exe file and click Copy File. In the list of Cluster dialog box, click Show File, and then click close. Next, locate the file by right-clicking the cluster number AC4(2756) and clicking Find File, and then click Yes in the warning message. When the search is done, click the search hit, AC4(2756), to display the cluster's content. Under Select the Disk(s)/Image(s) you want to search. Next, in the text box under the Search for the pattern(s) option button, type “FIF”. In the search dialog box, click the Cluster Search tab, if necessary and the Search for the pattern(s) option button, if they aren't already selected. Like most forensics tools, ProDiscover can read standard UNIX.dd image files. If the Auto Image Checksum message box opens, click Yes. Navigate to your work folder, click Co8Inchp.dd, and then click Open. To add an image file, click Action from the menu, point to Add, and click Image File. Enter Co8InChp as the project name, enter brief description and click Open. Click New Project and Enter Project Number (Lab4_StudentNumber) 3. Start ProDiscover Basic (Run as Administrator) 2. To process this case, make sure you have extracted the CosInChp.dd file to your work folder, and then follow these steps: 1. These false hits, referred to as false positives, require examining search hit to verify whether its what you are looking for. Because it's part of the label name of JFIF JPEG format, you might have several false hits if the USB drive contains several other JPEG files. The search string to use for this examination is "FIF”. Transcribed image text: In this lab you will learn how to use ProDiscover to search and extract possible evidence of JPEG files from the USB drive the EMTS manager gave you.
