  • FTK Imager
  • Xplico

The Sleuth Kit®

This software is basically a gathering of command line tools and a C library that permits one to scrutinize disk photos and retrieve files from them.  In addition, it is highly utilized behind the scenes in Autopsy and numerous other open-source and commercial forensics tools.

FTK Imager®

This tool is generally a data preview option and imaging software that genuinely lets you quickly evaluate electronic proof to decide if additional analysis with a forensic tool such as FTK® is authenticated.


In general terms, Xplico is a Network Forensics Analysis Tool (NFAT) that is used to rebuild the contents of investments functioned with a packet sniffer (e.g. Wireshark, tcpdump, Netsniff-ng).

Techniques Used in Cyber Forensics

Digital Investigators or Computer Forensics Experts utilize a series of tactics and techniques with a genuine usage of forensic tools to verify the copy of evidence document they have seized from a compromised computer or device.  In addition, they go for a search for hidden or encrypted folders and unallocated disk spaces for traces of deleted, encrypted, overwritten, or tampered files, and all the shreds of digital copies are nicely documented in a proper manner for filing a report duly admissible in the court of law without being harming the original source of the evidence and maintaining its integrity.

However, these Methods and Techniques of Cyber Forensics utilized by digital investigators are a combo of tricks, tactics, and techniques with a piece of expert knowledge.  Some of the prominent techniques are as the following:

Cross-Drive Analysis

This particular technique associates and counterparts datasets found on several computer drives to look for scrutinizing and maintain info regarding a forensic analysis.  Moreover, events that enhance the hunch are dedicatedly compared with data on another drive to watch for likeness and offer context.

Live Analysis:

In this particular tactic, a system is scrutinized from inside the operating system while the system or equipment is functioning, utilizing system tools on the computer.  In addition, the corresponding analysis of volatile data is generally stored in cache memory or RAM.  Several tools were utilized to obtain the volatile data need the computer in to be in a particular state within a forensic lab to keep up the integrity of the original source of the evidence.

Deleted Files Recovery:

As the name suggests, in this technique, forensics experts will be able to retrieve the database of the deleted files that were partially deleted in one place but left some traces elsewhere on the particular system while searching for a computer or any other corresponding device and even the memory for fragments of files.  Moreover, this individual technique is widely known as file carving or data carving.

Stochastic Forensics:-

In this technique, forensic experts scrutinize and rebuild the digital process without the usage of digital artifacts.  Furthermore, the artifacts are clues regarding a digital crime, like alterations to file characteristics during a data heist.  Moreover, stochastic forensics is continually utilized in data breach examinations where the hacker is pretended to be an insider who might not leave any digital artifacts behind.


It is a basic technique utilized to conceal data within any sort of digital file, context, or data stream.  In addition, computer forensic experts reverse a steganography effort by understanding the data hashing of a particular file to map its data of any corresponding size to a fixed length.  If, in case, any cyber criminal encrypts any confidential data inside an image, video, or any other digital file, it might be able to look exactly the same prior or after to the common perception; however, by the usage of the hash or string of data that portrays the image will transform.
