WEBVTT

0:00:04.100000 --> 0:00:08.080000
 In this video, we are going to create
 a live forensic image of a suspect's

0:00:08.080000 --> 0:00:11.740000
 hard disk drive using AccessData's
 FTK-Amager.

0:00:11.740000 --> 0:00:14.720000
 The tool version I am using in this
 lab is one that I have pre-installed

0:00:14.720000 --> 0:00:18.780000
 on my machine. In a real-life scenario,
 and assuming that the suspect's

0:00:18.780000 --> 0:00:22.680000
 machine won't have FTK-Amager installed,
 you can use the portable version

0:00:22.680000 --> 0:00:25.680000
 found in the reference section
 of module 2 slides.

0:00:25.680000 --> 0:00:29.440000
 All you need to do is copy the portable
 version to a USB drive.

0:00:29.440000 --> 0:00:33.400000
 You can then use that disk drive to
 run the tool from it and perform the

0:00:33.400000 --> 0:00:37.440000
 acquisition. Don't forget to add an
 external disk too so that you can

0:00:37.440000 --> 0:00:39.740000
 save your forensic image to it.

0:00:39.740000 --> 0:00:44.100000
 Before we create our forensic image,
 let's start the FTK-Amager.

0:00:44.100000 --> 0:00:48.580000
 As you can see, it is divided into
 four panes, the evidence tree pane,

0:00:48.580000 --> 0:00:52.640000
 the file list pane, the display pane,
 and the custom content sources pane

0:00:52.640000 --> 0:00:54.360000
 at the bottom left.

0:00:54.360000 --> 0:00:57.720000
 If we go to the file menu, we can see
 the available features that we can

0:00:57.720000 --> 0:01:00.600000
 use. We have the following
 options.

0:01:00.600000 --> 0:01:03.060000
 Add Evidence Item to Add Evidence.


0:01:03.060000 --> 0:01:06.240000
 Add all attached devices to add all
 the attached devices to the system

0:01:06.240000 --> 0:01:10.720000
 to the tool and image mounting, which
 is for mounting forensic images.

0:01:10.720000 --> 0:01:13.800000
 You can also see other features are
 disabled, like the Remove Evidence

0:01:13.800000 --> 0:01:16.960000
 Item, because we don't have any
 evidence added to the tool.

0:01:16.960000 --> 0:01:20.120000
 We'll address this in a later
 video, so don't worry.

0:01:20.120000 --> 0:01:23.900000
 Moving on, we see the Create Disk Image
 option, which we will be using

0:01:23.900000 --> 0:01:28.840000
 shortly. Here's the Capture Memory
 feature, which allows us to take a

0:01:28.840000 --> 0:01:31.840000
 forensic capture of the memory
 of the running system.

0:01:31.840000 --> 0:01:35.500000
 Finally, we have the Obtain
 Protected Files.

0:01:35.500000 --> 0:01:38.840000
 This is used to take a forensic image
 of files that are related to the

0:01:38.840000 --> 0:01:40.240000
 operating system.

0:01:40.240000 --> 0:01:43.380000
 These files are protected from being
 accessed or copied while the system

0:01:43.380000 --> 0:01:47.260000
 is running, like the system register your
 files related to the SAM database,

0:01:47.260000 --> 0:01:50.220000
 which stores user credentials
 on a system.

0:01:50.220000 --> 0:01:54.020000
 Before we use the Create Disk Image option,
 let's review the disks available

0:01:54.020000 --> 0:01:57.420000
 and how to do basic checks
 from within the system.

0:01:57.420000 --> 0:02:01.620000
 Let's go to My Computer and right-click
 on it, then select Manage to bring

0:02:01.620000 --> 0:02:03.920000
 up the Computer Management
 Console.

0:02:03.920000 --> 0:02:09.720000
 Now, let's navigate to the Disk Management
 section of the Computer Management

0:02:09.720000 --> 0:02:13.120000
 Console, which displays all
 drives on the machine.

0:02:13.120000 --> 0:02:16.400000
 As you can see, we have a pane that
 contains details about each volume

0:02:16.400000 --> 0:02:17.980000
 seen by the system.

0:02:17.980000 --> 0:02:22.440000
 And just below that, there's a pane
 showing the volumes based on disks.

0:02:22.440000 --> 0:02:24.620000
 We have Disk 0, which is Disk No.

0:02:24.620000 --> 0:02:27.320000
 1, although the counting
 here starts with 0.

0:02:27.320000 --> 0:02:31.000000
 We then have Disk 1, which is the second
 and Disk 2, which is the third

0:02:31.000000 --> 0:02:32.920000
 disk found on this computer.

0:02:32.920000 --> 0:02:36.240000
 The first disk is divided or partitioned
 into two partitions.

0:02:36.240000 --> 0:02:39.880000
 The first is the System Reserve Partition,
 which Microsoft uses to store

0:02:39.880000 --> 0:02:41.400000
 parts of the operating system.

0:02:41.400000 --> 0:02:47.240000
 As you can see, it has a size of 350
 megabytes and an NTFS file system.

0:02:47.240000 --> 0:02:51.300000
 Additionally, this partition is a system
 partition, as well as an active

0:02:51.300000 --> 0:02:53.060000
 primary partition.

0:02:53.060000 --> 0:02:57.700000
 The second partition is attached to the
 C drive and has a 99.66 gigabytes

0:02:57.700000 --> 0:03:01.300000
 of capacity, as well as
 an NTFS file system.

0:03:01.300000 --> 0:03:04.700000
 When selecting the partition, we can
 see the same details displayed in

0:03:04.700000 --> 0:03:09.240000
 a column-based detail
 in the pane above.

0:03:09.240000 --> 0:03:13.600000
 Now, if we go to the second disk disk
 1, we can see that the disk has

0:03:13.600000 --> 0:03:19.580000
 five partitions and the rest is free space,
 with a capacity of 523 megabytes.

0:03:19.580000 --> 0:03:23.880000
 If we select the first partition on
 the disk, we can see it has a 100

0:03:23.880000 --> 0:03:28.780000
 megabyte capacity, a FAT32 file system,
 it is a primary partition, has

0:03:28.780000 --> 0:03:32.920000
 the name FAT32PTA, and is mounted and
 attached to the drive letter X.

0:03:32.920000 --> 0:03:36.920000
 As you can see, the rest of the partitions
 are all the same size, but

0:03:36.920000 --> 0:03:40.240000
 the difference between them and the first
 is they are all logical drives,

0:03:40.240000 --> 0:03:44.740000
 not primary. The first logical partition
 is a FAT32 with 100 megabytes

0:03:44.740000 --> 0:03:48.380000
 of capacity and with
 a label of FAT32PTB.

0:03:48.380000 --> 0:03:53.180000
 The second, third, and fourth logical
 drives have 100 megabyte capacity,

0:03:53.180000 --> 0:04:03.840000
 an NTFS file system, and are named NTFS PTA,
 NTFS PTB, and NTFS PTC respectively.

0:04:03.840000 --> 0:04:07.940000
 NTFS PTA, the second logical drive,
 is the only one that is mounted and

0:04:07.940000 --> 0:04:10.560000
 attached to a drive
 letter, which is Y.

0:04:10.560000 --> 0:04:14.720000
 Looking at the third disk, we can see
 that it has 992 megabytes of disk

0:04:14.720000 --> 0:04:19.420000
 space, but it is completely unallocated,
 or at least, that is what the

0:04:19.420000 --> 0:04:21.380000
 disk management utility says.

0:04:21.380000 --> 0:04:24.820000
 As an investigator, you shouldn't only
 rely on that and do further checks

0:04:24.820000 --> 0:04:28.720000
 to ensure that it is not used to hide
 data in some unknown file system.

0:04:28.720000 --> 0:04:30.920000
 Please remember this point.

0:04:30.920000 --> 0:04:34.520000
 Let's go back to the FTK image or end
 starter acquisition process by going

0:04:34.520000 --> 0:04:37.940000
 to File, then Create Disk Image.

0:04:37.940000 --> 0:04:41.420000
 On the Select Source window, let me
 first explain the most commonly used

0:04:41.420000 --> 0:04:45.400000
 options. First is the Physical Drive
 option, which allows you to create

0:04:45.400000 --> 0:04:48.060000
 a forensic image from
 a physical disk drive.

0:04:48.060000 --> 0:04:52.060000
 This option takes a full copy of the physical
 drive with all the partitions,

0:04:52.060000 --> 0:04:54.660000
 unallocated space, etc.

0:04:54.660000 --> 0:04:58.040000
 Second is the logical drive option,
 which allows you to reach down to

0:04:58.040000 --> 0:05:01.240000
 a specific partition and take
 a forensic image of it.

0:05:01.240000 --> 0:05:03.860000
 Here, we are dealing
 with logical drives.

0:05:03.860000 --> 0:05:06.960000
 In other words, partitions, which is
 very useful when you don't want to

0:05:06.960000 --> 0:05:10.240000
 take a full image, especially when you
 know the exact partition you are

0:05:10.240000 --> 0:05:15.040000
 interested in. Third is the Image File
 option, which allows you to take

0:05:15.040000 --> 0:05:17.300000
 a forensic copy of
 a forensic copy.

0:05:17.300000 --> 0:05:21.460000
 It's just like making duplicates of the
 forensic copy, or you can convert

0:05:21.460000 --> 0:05:24.220000
 a forensic image from one
 format type to another.

0:05:24.220000 --> 0:05:29.300000
 For example, raw, DD to Advanced
 Forensic Format, AFF.

0:05:29.300000 --> 0:05:34.440000
 Lastly is the Contents of a folder
 option, which allows you to make a

0:05:34.440000 --> 0:05:36.860000
 forensic image of a
 specific directory.

0:05:36.860000 --> 0:05:39.640000
 You would select this choice when you
 want to take a forensic copy of

0:05:39.640000 --> 0:05:42.940000
 a specific directory or you don't have
 disk space available for all the

0:05:42.940000 --> 0:05:46.140000
 disk, and you're positively sure that
 a specific directory is all you

0:05:46.140000 --> 0:05:50.280000
 need. Let's first take a forensic
 image of a physical drive.

0:05:50.280000 --> 0:05:53.860000
 Let's select the first option,
 and then click Next.

0:05:53.860000 --> 0:05:56.240000
 We can now see the Select
 Drive window.

0:05:56.240000 --> 0:05:58.920000
 From here we can select the required
 drive we want to take a forensic

0:05:58.920000 --> 0:06:02.740000
 copy of. Make sure you know which drive
 you're interested in, because

0:06:02.740000 --> 0:06:05.040000
 you never know if you'll
 get a second chance.

0:06:05.040000 --> 0:06:08.940000
 Let's go back to the Disk Management
 Utility to make sure which disk we

0:06:08.940000 --> 0:06:10.640000
 want to forensically image.

0:06:10.640000 --> 0:06:13.760000
 Here, we'll check the drive names with
 the disk drives found in the Disk

0:06:13.760000 --> 0:06:14.660000
 Management Utility.

0:06:14.660000 --> 0:06:18.860000
 We can see that backwards slash backwards
 slash dot backwards slash, physical

0:06:18.860000 --> 0:06:25.800000
 drive 1 dash V-box hard disk,
 1 gigabyte, IDE is disk 1.

0:06:25.800000 --> 0:06:34.940000
 And, backwards slash backwards slash
 dot backwards slash physical drive

0:06:34.940000 --> 0:06:42.900000
 2 dash V-box hard disk 1 gigabyte
 IDE is actually disk 2.

0:06:42.900000 --> 0:06:46.340000
 Take note that here we can see the word
 V-box in the name of the physical

0:06:46.340000 --> 0:06:49.820000
 drive, and the reason for that is because
 we're doing this video using

0:06:49.820000 --> 0:06:52.400000
 a VirtualBox Virtual Machine.

0:06:52.400000 --> 0:06:55.560000
 Realistically, we might get a
 different manufacturer name.

0:06:55.560000 --> 0:06:57.820000
 Again, just be careful.

0:06:57.820000 --> 0:07:01.720000
 Now, since I'm interested in Disk 1,
 I will go ahead and select the drive

0:07:01.720000 --> 0:07:05.640000
 backwards slash backwards slash dot backwards
 slash physical drive 1 dash

0:07:05.640000 --> 0:07:11.320000
 V-box hard disk 1 gigabyte
 IDE, and then click Finish.

0:07:11.320000 --> 0:07:15.840000
 In the Create Image window, backwards
 slash backwards slash dot backwards

0:07:15.840000 --> 0:07:20.000000
 slash physical drive 1 is selected
 in the image source field just like

0:07:20.000000 --> 0:07:24.820000
 we wanted. Let's click Add to
 select the image destination.

0:07:24.820000 --> 0:07:29.940000
 In the Select Image Type window, we'll
 select the raw DD image type, which

0:07:29.940000 --> 0:07:34.180000
 is the default here,
 and then click Next.

0:07:34.180000 --> 0:07:37.380000
 The Evidence Item Information window
 can be used to add information to

0:07:37.380000 --> 0:07:39.240000
 the evidence we are acquiring.

0:07:39.240000 --> 0:07:42.760000
 We can add information like Case Number,
 Evidence Number, a unique description

0:07:42.760000 --> 0:07:46.760000
 for our evidence, the name of the person
 that did the examination, and

0:07:46.760000 --> 0:07:49.360000
 any other notes that could
 be helpful later.

0:07:49.360000 --> 0:07:52.780000
 Let's go ahead and fill
 in the information here.

0:07:52.780000 --> 0:08:00.100000
 For the case, we'll use Case
 001, since it's the first.

0:08:00.100000 --> 0:08:04.120000
 001 is the evidence number because we're
 assuming this is the first evidence.

0:08:04.120000 --> 0:08:06.980000
 We'll also give the forensic
 image a unique description.

0:08:06.980000 --> 0:08:11.240000
 Let's use Disk Image Number 1, because
 this is the first disk image we're

0:08:11.240000 --> 0:08:16.340000
 doing. In the Examiners field, I'll
 add my name, so later on we know who

0:08:16.340000 --> 0:08:18.520000
 made the acquisition
 for this evidence.

0:08:18.520000 --> 0:08:22.100000
 In the Notes section, let's add that
 this is a raw image for the first

0:08:22.100000 --> 0:08:30.500000
 disk number 1, and then
 click the Next button.

0:08:30.500000 --> 0:08:34.440000
 In the Select Image Destination window,
 we need to specify where to store

0:08:34.440000 --> 0:08:36.840000
 the forensic image we
 will be creating.

0:08:36.840000 --> 0:08:41.580000
 For this video, it will be on the same
 machine, but in a real-life scenario,

0:08:41.580000 --> 0:08:45.160000
 you will usually be copying it to
 an external drive or location.

0:08:45.160000 --> 0:08:48.400000
 Let's click the Browse
 button to proceed.

0:08:48.400000 --> 0:08:51.300000
 All images for the course are on the
 desktop within a directory named

0:08:51.300000 --> 0:08:56.300000
 Cases. Inside the Cases directory,
 let's create another directory for

0:08:56.300000 --> 0:08:59.900000
 this specific case,
 naming it Case 001.

0:08:59.900000 --> 0:09:05.620000
 Also, within the Case 001 directory,
 we'll create another directory for

0:09:05.620000 --> 0:09:09.620000
 this evidence, which will name Disk 01,
 because it's the first disk we're

0:09:09.620000 --> 0:09:11.840000
 going to acquire for
 evidence gathering.

0:09:11.840000 --> 0:09:15.920000
 Within the directory, let's create
 another directory called Images.

0:09:15.920000 --> 0:09:19.360000
 This structure depends on you and how
 you want to categorize your evidence.

0:09:19.360000 --> 0:09:22.620000
 This is only one way to sort and categorize
 the evidence for a specific

0:09:22.620000 --> 0:09:27.220000
 case. Now, let's click
 OK to proceed.

0:09:27.220000 --> 0:09:31.500000
 In the Image File name, excluding Extension
 field, let's name the forensic

0:09:31.500000 --> 0:09:36.020000
 image we're going to acquire, Disk 01
 underscore Image 01, because this

0:09:36.020000 --> 0:09:40.180000
 image will be long to the first disk,
 and it is the first image taken.

0:09:40.180000 --> 0:09:44.080000
 We can now see a field for Image Fragment
 Size Megabytes, which can be

0:09:44.080000 --> 0:09:46.880000
 used in case the drive you're willing
 to acquire could not fit on the

0:09:46.880000 --> 0:09:48.320000
 destination you have.

0:09:48.320000 --> 0:09:51.400000
 As an example, you may not have a disk
 drive that could hold the whole

0:09:51.400000 --> 0:09:54.880000
 image, and you may want to take a forensic
 image of a disk drive and then

0:09:54.880000 --> 0:09:57.000000
 copy them to DVD drives.

0:09:57.000000 --> 0:10:01.400000
 Let's make this zero, which means
 to not fragment the image.

0:10:01.400000 --> 0:10:04.940000
 It will leave the forensic image exactly
 as it is, with no slicing to

0:10:04.940000 --> 0:10:09.100000
 it. The Use AD Encryption option can
 be used to add a password to the

0:10:09.100000 --> 0:10:12.660000
 forensic image. With this selected,
 you will be asked to add a password

0:10:12.660000 --> 0:10:15.980000
 for the image, and whenever an investigator
 wants to mount the forensic

0:10:15.980000 --> 0:10:19.980000
 image and access its content, he or
 she will have to enter the password

0:10:19.980000 --> 0:10:24.120000
 open it. It's a way to secure your evidence
 with a password and is very

0:10:24.120000 --> 0:10:27.880000
 useful. Now, let's click Finish.

0:10:27.880000 --> 0:10:30.420000
 We're now back at the
 Create Image window.

0:10:30.420000 --> 0:10:33.560000
 Let's unselect the Create Directory
 listings for all files in the image

0:10:33.560000 --> 0:10:35.840000
 after they are created option.

0:10:35.840000 --> 0:10:38.500000
 Don't worry, I'll
 explain why later.

0:10:38.500000 --> 0:10:41.960000
 Let's click on the Start button to
 start the acquisition process.

0:10:41.960000 --> 0:10:45.960000
 The Create Image window now shows the
 source of the image, the destination

0:10:45.960000 --> 0:10:49.900000
 where it will be stored, the status
 that the FTK image is truly creating

0:10:49.900000 --> 0:10:53.860000
 the image, a progress bar showing how
 much progress has been made, and

0:10:53.860000 --> 0:10:56.760000
 he lapsed time field to give us an
 idea of how much time the tool has

0:10:56.760000 --> 0:11:01.340000
 taken up until now, and, finally, the
 estimated time left to complete

0:11:01.340000 --> 0:11:02.720000
 the forensic image.

0:11:02.720000 --> 0:11:06.140000
 You may be wondering why the
 copy was extremely fast.

0:11:06.140000 --> 0:11:09.540000
 Just remember that this depends on different
 issues, but one of the most

0:11:09.540000 --> 0:11:11.140000
 important factors
 here is the site.

0:11:11.140000 --> 0:11:14.160000
 The size of the disk we are
 acquiring is not too big.

0:11:14.160000 --> 0:11:18.660000
 In the Status field, we can see that it
 now says Image created successfully,

0:11:18.660000 --> 0:11:22.160000
 and immediately after that the Verifying
 window appears and starts doing

0:11:22.160000 --> 0:11:27.720000
 calculations. Now that the imaging process
 is finished, FTK Image performs

0:11:27.720000 --> 0:11:32.060000
 two hashing operations to verify that
 the acquisition was successful.

0:11:32.060000 --> 0:11:36.700000
 In the Drive Forward slash image Verify
 Results window, we can see the

0:11:36.700000 --> 0:11:40.200000
 name of the forensic image that we
 chose, and the number of sectors in

0:11:40.200000 --> 0:11:45.860000
 the disk. Under the MD5 hash section,
 we see the Computed hash, Reported

0:11:45.860000 --> 0:11:50.020000
 hash, and Verify results, showing that
 both the computed and reported

0:11:50.020000 --> 0:11:55.380000
 truly match. Under the SHA1 hash section,
 we can also see the Computed

0:11:55.380000 --> 0:11:58.980000
 hash and reported hash, which shows
 us that the Verify result for both

0:11:58.980000 --> 0:12:02.000000
 the computed and reported
 also truly match.

0:12:02.000000 --> 0:12:05.940000
 Finally, we see the Bad Sector List
 section, which shows that there are

0:12:05.940000 --> 0:12:09.720000
 no bad sectors. Let's go ahead and close
 this window, and the Create Image

0:12:09.720000 --> 0:12:15.860000
 window too. Let's go to the Cases directory
 and look inside to check that

0:12:15.860000 --> 0:12:17.360000
 it was done successfully.

0:12:17.360000 --> 0:12:20.840000
 We can see that all the directories
 we created are there, and inside the

0:12:20.840000 --> 0:12:23.240000
 Images directory we see two files.


0:12:23.240000 --> 0:12:26.320000
 The first file is the actual raw image
 of the disk we just forensically

0:12:26.320000 --> 0:12:30.520000
 imaged. The second file contains information
 from when the image was created,

0:12:30.520000 --> 0:12:32.300000
 and info was added.

0:12:32.300000 --> 0:12:35.260000
 On the first line, we can see the Tool
 and Tool version used to create

0:12:35.260000 --> 0:12:38.560000
 this image. For instance, below.

0:12:38.560000 --> 0:12:43.200000
 We see the Case number, Evidence number,
 and, if you recall, we chose

0:12:43.200000 --> 0:12:46.460000
 001 as it was the first evidence.

0:12:46.460000 --> 0:12:50.260000
 We also used the Unique Description,
 My Name on the Examiners line, and

0:12:50.260000 --> 0:12:52.080000
 the notes we added too.

0:12:52.080000 --> 0:12:55.800000
 Further below, in the Drive Geometry section,
 we see the number of cylinders

0:12:55.800000 --> 0:12:59.780000
 in the drive, the sectors per track,
 and the bytes per sector, which is

0:12:59.780000 --> 0:13:04.260000
 extremely important even though most
 disks use 512 bytes, but there are

0:13:04.260000 --> 0:13:05.860000
 other advanced types.

0:13:05.860000 --> 0:13:10.360000
 We also see the number of sectors
 counted on the sectors count line.

0:13:10.360000 --> 0:13:15.220000
 In the computed hashes section, we
 see the check sums for both MD5 and

0:13:15.220000 --> 0:13:18.320000
 SHA1 are calculated.

0:13:18.320000 --> 0:13:21.540000
 In the Image Verification Results section,
 we can see when the verification

0:13:21.540000 --> 0:13:26.640000
 started and finished, as well as
 the MD5 and SHA1 check sums.

0:13:26.640000 --> 0:13:28.660000
 Both show is verified.

0:13:28.660000 --> 0:13:30.920000
 Before we move on,
 let's look at this.

0:13:30.920000 --> 0:13:33.980000
 It shows the location where we have
 stored our forensic image and its

0:13:33.980000 --> 0:13:37.700000
 name. Let's go ahead
 and close this now.

0:13:37.700000 --> 0:13:40.980000
 Let's now do another forensic image,
 but this time instead of creating

0:13:40.980000 --> 0:13:45.860000
 a forensic image of the raw DD,
 we will now do one of Type AFF.

0:13:45.860000 --> 0:13:50.060000
 Like before, we'll go to File, then Create
 Disk Image, and before we select

0:13:50.060000 --> 0:13:53.900000
 the drive, let's again double check which
 drive or partition we are interested

0:13:53.900000 --> 0:14:07.180000
 in. Let's select the second disk
 again, disk 1, and click Finish.

0:14:07.180000 --> 0:14:10.620000
 Now, let's choose where we want to
 store this image by clicking on the

0:14:10.620000 --> 0:14:15.240000
 Add button. Since we are making a forensic
 image using an image of Type

0:14:15.240000 --> 0:14:19.060000
 AFF, let's select the last
 option and press Next.

0:14:19.060000 --> 0:14:22.960000
 Again, like before, we need to add
 some information to the evidence we

0:14:22.960000 --> 0:14:27.640000
 are acquiring. Let's add this to Case
 001, but since this is the second

0:14:27.640000 --> 0:14:29.900000
 evidence, I wrote 002.

0:14:29.900000 --> 0:14:35.060000
 Let's use Disk Image number 2
 for the unique description.

0:14:35.060000 --> 0:14:37.000000
 I'll use my name for the examiner.


0:14:37.000000 --> 0:14:49.960000
 In the Notes section, let's put
 AFF image for Disk number 1.

0:14:49.960000 --> 0:14:53.220000
 Now that we're all done,
 let's click Next.

0:14:53.220000 --> 0:14:56.900000
 Here, we'll select the destination
 to store the forensic image.

0:14:56.900000 --> 0:15:00.200000
 Let's do that by clicking Browse and
 going to the directory we created

0:15:00.200000 --> 0:15:05.860000
 and select it. Now, let's specify
 the name for the forensic image.

0:15:05.860000 --> 0:15:10.540000
 Let's add the name Disk 1, underscore
 Image 02 in the image file name

0:15:10.540000 --> 0:15:14.900000
 field. Now let's specify that we don't
 want to fragment the forensic image,

0:15:14.900000 --> 0:15:18.700000
 which is why image fragment
 size was changed to 0.

0:15:18.700000 --> 0:15:21.520000
 Next, we'll add a password
 to this evidence.

0:15:21.520000 --> 0:15:26.280000
 So let's select the Use AFF Encryption
 and then click Finish.

0:15:26.280000 --> 0:15:29.420000
 Now we have a small window
 for the AFF Encryption.

0:15:29.420000 --> 0:15:32.760000
 I'll add my password
 twice and click OK.

0:15:32.760000 --> 0:15:37.800000
 We're not done yet.

0:15:37.800000 --> 0:15:40.260000
 I still want to show you
 another feature here.

0:15:40.260000 --> 0:15:43.440000
 Let's select the Create Directory listing
 of all files in the image after

0:15:43.440000 --> 0:15:45.140000
 their created option.

0:15:45.140000 --> 0:15:48.220000
 Everything is good,
 so let's start.

0:15:48.220000 --> 0:15:51.280000
 We now see the Creating Image window,
 which shows the details that were

0:15:51.280000 --> 0:15:52.540000
 explained earlier.

0:15:52.540000 --> 0:15:55.580000
 Also, this won't take too much time
 because the disk we're imaging is

0:15:55.580000 --> 0:16:04.000000
 small. Let's check the results of the
 verification and make sure all was

0:16:04.000000 --> 0:16:07.340000
 done properly. We can see the
 sector count and the hashes.

0:16:07.340000 --> 0:16:10.340000
 They all match and there are no bad
 sectors, which is good for us.

0:16:10.340000 --> 0:16:13.660000
 Let's close the Creating Directory
 listing window and the Create Image

0:16:13.660000 --> 0:16:15.620000
 window and continue.

0:16:15.620000 --> 0:16:28.860000
 Again, let's check the files
 that were created.

0:16:28.860000 --> 0:16:31.060000
 We have three files.

0:16:31.060000 --> 0:16:34.220000
 The first file is the forensic
 image of type AFF.

0:16:34.220000 --> 0:16:35.940000
 Take note of the file size.

0:16:35.940000 --> 0:16:39.520000
 It's only around 20 megabytes compared
 to the RYM-age, which is more than

0:16:39.520000 --> 0:16:44.100000
 1 gigabyte. The reason for the size difference
 is that AFF supports compression,

0:16:44.100000 --> 0:16:46.580000
 while RAW does not
 compress the image.

0:16:46.580000 --> 0:16:50.300000
 Before we check the Excel sheet,
 let's check the text file.

0:16:50.300000 --> 0:16:52.960000
 As you can see, it's
 the same as before.

0:16:52.960000 --> 0:16:55.680000
 The first line shows what tool and version
 were used to create this forensic

0:16:55.680000 --> 0:16:59.860000
 image, while the rest of the lines
 show the specific details we added

0:16:59.860000 --> 0:17:02.760000
 during our forensic
 image creation.

0:17:02.760000 --> 0:17:08.260000
 In the Drive Geometry section, we have
 the Drive Details, Cylinders, Tracks,

0:17:08.260000 --> 0:17:11.240000
 Sector Size, Number
 of Sectors, etc.

0:17:11.240000 --> 0:17:14.700000
 Here we can see the name of the forensic
 image and the storage location.

0:17:14.700000 --> 0:17:19.160000
 Below, near the end of the file, are
 the computed and reported hashes,

0:17:19.160000 --> 0:17:20.640000
 which are verified.

0:17:20.640000 --> 0:17:24.960000
 You can check that yourself by comparing
 the MD5 checksum here with the

0:17:24.960000 --> 0:17:27.060000
 one in the computed
 hashes section.

0:17:27.060000 --> 0:17:29.000000
 Okay, let's move on.

0:17:29.000000 --> 0:17:32.720000
 Let's now open the Excel
 sheet and check it out.

0:17:32.720000 --> 0:17:35.080000
 Let's expand these columns
 to see what's there.

0:17:35.080000 --> 0:17:38.500000
 First, we have the file name and then
 the full path to the file on the

0:17:38.500000 --> 0:17:51.620000
 disk drive. Some entries show
 no file name, only numbers.

0:17:51.620000 --> 0:17:55.460000
 Don't worry about these entries, we'll
 discuss it in the next module.

0:17:55.460000 --> 0:17:58.480000
 Take note that the file contains a directory
 listing for each partition

0:17:58.480000 --> 0:18:00.020000
 within the whole disk.

0:18:00.020000 --> 0:18:03.720000
 Here we have the directory listing
 for the FAT32 partition.

0:18:03.720000 --> 0:18:06.620000
 Let's continue expanding the columns
 until we see the size of the file

0:18:06.620000 --> 0:18:07.960000
 in the time stamps.

0:18:07.960000 --> 0:18:22.620000
 As you can see here, we have the directory
 listing for the NTFS partition.

0:18:22.620000 --> 0:18:25.640000
 Again, don't worry about these unusual
 names and what they are, we'll

0:18:25.640000 --> 0:18:28.240000
 discuss this at a later time.

0:18:28.240000 --> 0:18:36.540000
 Let's close the Excel
 sheet and continue.

0:18:36.540000 --> 0:18:40.560000
 We have done a forensic image for the
 full disk drive, but what if we're

0:18:40.560000 --> 0:18:42.580000
 interested in only a partition?

0:18:42.580000 --> 0:18:44.480000
 Let's see how to do that.

0:18:44.480000 --> 0:18:49.820000
 Again, let's go to File, then create
 disk image, but this time, let's

0:18:49.820000 --> 0:18:53.880000
 select the logical drive option
 and then click Next.

0:18:53.880000 --> 0:18:57.160000
 In the Select Drive window, the drop
 down list does not show physical

0:18:57.160000 --> 0:19:00.680000
 drives, but this time shows
 logical partitions.

0:19:00.680000 --> 0:19:04.600000
 We're taking a forensic image for the
 X partition that has a FAT32 file

0:19:04.600000 --> 0:19:08.240000
 system. Now, click Finish.

0:19:08.240000 --> 0:19:12.400000
 In the Create Image window, take notice
 in the Image Source that the partition

0:19:12.400000 --> 0:19:14.080000
 we're imaging is X.

0:19:14.080000 --> 0:19:17.840000
 Let's go ahead and add a destination
 by clicking the Add button.

0:19:17.840000 --> 0:19:22.020000
 Let's make a raw DD image
 this time and click Next.

0:19:22.020000 --> 0:19:25.740000
 Now, in the Evidence Item Information
 window, let's add all the details

0:19:25.740000 --> 0:19:27.620000
 we need for this case.

0:19:27.620000 --> 0:19:31.840000
 We're still working on Case
 1, so this is Case 001.

0:19:31.840000 --> 0:19:36.540000
 This is our third evidence though, so
 let's use 003 and Disk 1 Partition

0:19:36.540000 --> 0:19:42.020000
 number 1 will be the
 unique description.

0:19:42.020000 --> 0:19:45.240000
 I'll add my name to the Examiners field
 and make the final note as Raw

0:19:45.240000 --> 0:19:48.680000
 Image for Disk at Partition
 number 1.

0:19:48.680000 --> 0:20:02.440000
 Now that that's complete, let's
 click Next to proceed.

0:20:02.440000 --> 0:20:04.880000
 We need to select where to
 store the forensic image.

0:20:04.880000 --> 0:20:08.600000
 Let's click Browse and then navigate
 to the location I want and click

0:20:08.600000 --> 0:20:15.560000
 OK. Now let's give this image a name,
 Disk 1 Partition 1 underscore FAT32.

0:20:15.560000 --> 0:20:22.540000
 Let's change the fragment to 0 so that
 the FTK Emager does not fragment

0:20:22.540000 --> 0:20:24.180000
 the forensic image.

0:20:24.180000 --> 0:20:27.140000
 Now, let's click Finish
 to proceed.

0:20:27.140000 --> 0:20:29.620000
 This time we don't want to create a
 directory listing for their forensic

0:20:29.620000 --> 0:20:33.780000
 image. That is, we don't want to create
 the Excel sheet and can continue

0:20:33.780000 --> 0:20:35.400000
 by pressing Start.

0:20:35.400000 --> 0:20:38.500000
 Since this is only an image for a single
 small partition, it will finish

0:20:38.500000 --> 0:20:42.940000
 extremely fast. Even the verification
 won't take too much time to calculate.

0:20:42.940000 --> 0:20:47.300000
 Let's check the verification
 results.

0:20:47.300000 --> 0:20:50.640000
 As you can see, the computed
 MD5 hashes match.

0:20:50.640000 --> 0:20:55.060000
 The computed SHA1 hashes also match
 and there are no bad sectors.

0:20:55.060000 --> 0:20:58.760000
 We seem to be lucky, right?

0:20:58.760000 --> 0:21:03.020000
 Before we close this window, we can see
 the number of sectors found here.

0:21:03.020000 --> 0:21:07.020000
 If you multiply this number with 512,
 which is the number of bytes, you

0:21:07.020000 --> 0:21:11.120000
 will get 104,857,600 bytes.

0:21:11.120000 --> 0:21:17.100000
 And by dividing it by 1,024,
 we get 102,400 kilobytes.

0:21:17.100000 --> 0:21:22.140000
 If we divide it again by 1,024, we get
 100 megabytes, which is the exact

0:21:22.140000 --> 0:21:24.100000
 size of the partition.

0:21:24.100000 --> 0:21:27.540000
 We'll be doing lots of calculations
 later on, so it's good to get used

0:21:27.540000 --> 0:21:30.780000
 to it early. Let's close
 all open windows.

0:21:30.780000 --> 0:21:33.980000
 Let's now make sure the directory listing
 was done successfully, as well

0:21:33.980000 --> 0:21:35.300000
 as the image too.

0:21:35.300000 --> 0:21:39.800000
 Let's check the directory where
 we store the forensic image.

0:21:39.800000 --> 0:21:42.820000
 As you can see, we
 have three files.

0:21:42.820000 --> 0:21:45.880000
 One file is for the image,
 which is 100 megabytes.

0:21:45.880000 --> 0:21:49.160000
 Another file is for the Excel sheet for
 the directory listing, and another

0:21:49.160000 --> 0:21:52.420000
 is the text file that holds the metadata
 information about our forensic

0:21:52.420000 --> 0:21:55.800000
 image and how it was created.

0:21:55.800000 --> 0:21:59.120000
 If we bring back the disk management
 window, we can see that the partition

0:21:59.120000 --> 0:22:02.920000
 we acquired is attached
 to the drive letter X.

0:22:02.920000 --> 0:22:07.640000
 The partition has a FAT32 file system
 and a capacity of 100 megabytes.

0:22:07.640000 --> 0:22:14.320000
 Let's open the text file
 and double check it.

0:22:14.320000 --> 0:22:19.420000
 As you can see, the forensic image was
 created using Access Data FTK Emager,

0:22:19.420000 --> 0:22:21.500000
 and the version numbers
 on the first line.

0:22:21.500000 --> 0:22:23.940000
 All the rest of the image information
 we added during the acquisition

0:22:23.940000 --> 0:22:32.800000
 is here too. If we scroll down, we can
 see the image name and its location.

0:22:32.800000 --> 0:22:36.880000
 In the Image Verification Results section,
 we can see when the verification

0:22:36.880000 --> 0:22:41.540000
 started and ended, as well as the calculated
 check sums for both MD5 and

0:22:41.540000 --> 0:22:45.140000
 SHA1, which was verified
 successfully.

0:22:45.140000 --> 0:22:48.620000
 In the Physical Drive Information section,
 we'll find the source data

0:22:48.620000 --> 0:22:53.160000
 size reported as 100 megabytes, just
 like what we calculated earlier.

0:22:53.160000 --> 0:22:56.600000
 The sector count is also 204,800.

0:22:56.600000 --> 0:23:01.360000
 Great. One final note to mention here,
 when looking at the source type,

0:23:01.360000 --> 0:23:05.140000
 you see that it is a logical drive and
 not what we will get when we select

0:23:05.140000 --> 0:23:07.940000
 to image the full physical
 disk drive.

0:23:07.940000 --> 0:23:11.200000
 Let's open the text file for the disk
 image we created and double check

0:23:11.200000 --> 0:23:19.200000
 this. As you can see, the source type
 for the disk is physical while it

0:23:19.200000 --> 0:23:22.380000
 shows logical for the partition
 we just acquired.

0:23:22.380000 --> 0:23:26.860000
 Before closing the text file for the
 partition, let's look at the Image

0:23:26.860000 --> 0:23:28.660000
 Information section.

0:23:28.660000 --> 0:23:32.100000
 We can see the date and time when
 the acquisition started and ended.

0:23:32.100000 --> 0:23:33.740000
 Okay, that's it here.

0:23:33.740000 --> 0:23:36.300000
 Let's close this file.

0:23:36.300000 --> 0:23:38.860000
 Now, let's open the Excel sheet.

0:23:38.860000 --> 0:23:43.080000
 Again, let's expand the columns
 just to see what's there.

0:23:43.080000 --> 0:23:51.280000
 As you can see, we have a column for
 the file name, the full path, the

0:23:51.280000 --> 0:23:56.100000
 size and bytes, the creation modification
 and access timestamps, and finally,

0:23:56.100000 --> 0:23:57.680000
 the deleted column.

0:23:57.680000 --> 0:24:00.540000
 Let's close this.

0:24:00.540000 --> 0:24:04.600000
 In this video, we went through creating
 a forensic image for a full disk,

0:24:04.600000 --> 0:24:09.060000
 which was disk 1, as well as how to create
 a forensic image of a partition.

0:24:09.060000 --> 0:24:13.100000
 We also showed how to make a raw DD
 image and an AFF image, and briefly

0:24:13.100000 --> 0:24:17.060000
 explained the benefits of using
 an AFF over the DD type.

0:24:17.060000 --> 0:24:20.660000
 By watching this video, you should
 now know how to identify disks and

0:24:20.660000 --> 0:24:24.580000
 partitions from the disk
 management utility.

0:24:24.580000 --> 0:24:28.360000
 And this concludes our training video
 on creating a forensic image using

0:24:28.360000 --> 0:24:30.680000
 AccessData's FTK Imager.

0:24:30.680000 --> 0:24:31.640000
 Thank you for joining us.
