Forensic wiping of all data on hard disk drivesĭc3dd was developed by the Department of Defense Cyber Crime Center and is updated whenever DD updates.

Bitstream (raw) disk acquisition and cloning.

Be sure to always first identify your devices, partitions, input and output files, and parameters when using DD and dc3dd. Hence, you may find that DD is sometimes also fondly referred to as the Data Destroyer. Using dc3dd in Kali Linuxīefore we get started using dc3dd, I need to again draw your attention to one of the features of DD: being able to wipe data, partitions, and drives. Now that we can identify our devices and create MD5 and SHA-1 hashes in Kali Linux, let's move on to using dc3dd in the next section. You may also try the command with superuser privileges by typing in sudo md5sum /dev/sdx.įor this example, the 2 GB flash drive that I'll be using (named test_usb) is recognized as sdb and the command I will be using is shown in the following screenshot:įigure 5.4 – Creating an SHA1 hash using sha1sum In Kali Linux, we can use the md5sum command, followed by the path of the device, to create an MD5 hash of the evidence/input file – for example, md5sum /dev/sdx. In order to provide proof that the evidence was not tampered with, a hash of the evidence should be provided before and during, or after, an acquisition. Be sure to use the fdisk -l command t o identify your drives and pa rtitions. Now that we've distinguished and become certain of which drive is to be imaged ( sdb), we can begin the forensic imaging using dc3dd.Īlthough I have used an older 2 GB flash drive to demonstrate the usage of dc3dd, you can use any drive (portable or otherwise) to practice using the tools in this chapter.

sdb: Flash drive to be forensically acquired or imaged.

sda: Primary hard disk with three partitions.

The primary partition is listed as sda1, with the Extended and Linux swap partitions listed as sda2 and sda5, respectively:įigure 5.2 – Full output of the fdisk command in Kali LinuxĪs seen in the preceding screenshots (and also explained earlier in this chapter), Kali Linux recognizes two devices: The fdisk-1 command has been executed in the following screenshot. The sudo command allows the user to run the command as root, which is similar to the Run as Administrator feature in Windows. The sudo fdisk -l command may have to be used if the previous one does not work. To list your devices and ensure that you are aware of them before performing any acquisition operations, the fdisk -l command should be run before any other. It's also important to remember to continue using your write blocker when acquiring and creating forensic images of evidence and drives, in order to not write data to the drives or modify the original evidence files. At this point, we should consider attaching our media to a write blocker before examining it.

sdb1: Partition 1 on the second disk ( sdb)ĭevice identification using the fdisk commandįor the exercises in this chapter, I'll be using an old 2 GB flash drive for the acquisition process using dc3dd.sda1: Partition 1 on the first disk ( sda).

While Windows recognizes partitions as primary, logical, and extended, Linux partitions are recognized as numbers after the drive letter:

sda: Drive 0, or the first drive recognized.

The sd stands for SCSI Mass-Storage Driver, with the letter after it representing the drive number:

/sda: Refers to the Small Computer System Interface ( SCSI), SATA, and USB devices.

/dev: Refers to the path of all devices and drives, which can be read from or written to, recognized by Linux.

Users new to Kali Linux or any Linux variations may find that the drive, partition recognition, and naming in Kali Linux are different from that of Windows devices.Ī typical device in Linux can be addressed or recognized as /dev/sda, whereas drives in Windows are usually recognized as Disk 0, Disk 1, and so on:

dc3dd is a patch of the very popular Data Dump ( DD) tool used for forensic acquisition and hashing. The first tool we will use for acquisition is called Department of Defense Cyber Crime Center Data Dump ( dc3dd). Using the Guymager GUI for data acquisition.In this chapter, we will cover the following topics: In this chapter, we will demonstrate forensically sound techniques for the acquisition of data using bitstream copies, including creating data hashes, in keeping with best practices. These ensure the integrity of the investigation by providing proof of data authenticity and preservation of the original evidence and documentation, which can be used to achieve the same exact results if the usage of tools and methods are repeated. In the previous chapter, we learned that documentation and proper procedures are key in any investigation. Chapter 5: Evidence Acquisition and Preservation with dc3dd and Guymager
