This prevents modification to the evidence.A few days ago, we talked about the benefits and capabilities of Forensic Toolkit (FTK), which is a computer forensics software application provided by AccessData, as well as how to download your own free copy. Even recently deleted files can be exported.This is the way how forensic analysis is done. A tool is utilized to load the image, and it is seen and examined as a disk. and started to image the drive.Īfter the image was created, the following window shows up. From here the files can be be seen or sent out to disk. After that the case for investigation has been built.Īfter previous step I created a file called USB Investigation Under the DATA drive. Also, we have to select the destination image type as Raw (dd). Then we created image, and we have to make sure that we checked verifying images after they are created. Next, we chose the drive that we wanted to image. I checked “Physical Drive” then click “Next”. Then in the next screen, there is a list sources. Next, Click “File” then “Create Disk Image”.

Then I Opened the FTK Imager in Windows Explorer to start the program. then I copied the folder hashing to the USB drive.

Next, I connected a USB drive to the computer. To image a USB drive we use a GUI program. AccessData has an imaging tool called FTK Imager.Īfter downloaded FTK Imager from the link ( ) and saved it in the Downloads folder. So, we can see that a small change can make huge differences in hashing. After browsing for the folder “ hashing”.Īs we can see above the tow files hash1 and hash2 have identical values, but hash3 is different because it was altered. Then double click hashmyfile.exe.Īfter running hashmyfiles.exe, I clicked on the “Add Folder” icon to add the folder “hashing” to calculate hash values of these files. The program calculates three hash values automatically: MDA, SHA1, and CRC32.

Then I downloaded zip file named hashmyfiles.zip to your Downloads folder and unzip it. As we can see the first two files hash1 and hash2 still have the same content, but the third file ( hash3) has a single letter changed. Next, I made a change in hash3 by Changing the first letter of Investigation from uppercase letter I to lowercase letter i and saved the changes. Using the same file content to create two new files by clicking “File” and “Save as”. A more popular approach is to also store checksums (hashes) (message digests) of files for later comparison.Īfter logging into our Windows system, Under Downloads folder we created a new folder named “ hashing“. Then inside “ hashing” folder we created a new text document, we named “ hash1“. Next, I opened the text document and I typed “ Computer Forensics Investigation is fun and challenging.” then I clicked “File” and “Save”. ViceVersa supports both types of file verification.

In this Lab-4 we will learn how Imaging works and how to verify the images using hash values, understand how hash values are used to authenticate duplicated digital images, observe how small changes make big differences in hash values. Demonstrating how a little change can have a tremendous effect in hash value.įile Verification is the procedure of checking that a document has not been changed and/or that two documents are indistinguishable, bit by bit. As it was described in the lecture previously, hashing is a powerful and pervasive technique used in nearly every examination of seized digital media, and a way to fingerprint files, partitions, or entire hard drives.
