Top 10 Cyber Forensics Investigative & Analysis Tools for Experts

The art of Cyber forensic investigation is quite complex and requires rigorous precision in following every investigative step from Acquisition to Analysis & Reporting. Experts now face the need for dependable tools that help them to do so, from the beginning. Every investigation requires the usage of multiple tools, dependence on a sole tool causes the investigation to lose its flexibility and makes it prone to ambiguity. So, in this article, we have explained the top digital forensic tools using which the investigators can get the best results.

When an Investigator raids a crime scene, he is greeted with multitudes of evidence from a computer to a simple mobile. So the examiner requires multiple tools that could help perform hard drive, volatile memory, and network & email forensics.

List of Top Digital Forensic Tools by the Practitioners:

1. MailXaminer

MailXaminer is the Flagship product developed by SysTools Software, which is an efficient email forensic examination tool. The software runs on the Windows platform and supports Web-based, Desktop Based and Cloud-Based Emails. It provisions an investigator to maintain a case repository, scan email evidence and search within them by using search options such as Advanced Search, Fuzzy, Wildcard, Predefined, Regular Expression, Stem Search and much more. MailXaminer also features an important email forensic feature utilization i.e. Skin tone analysis (detecting obscene Images, especially used in CP) in the suspect emails.

The key feature of the software is that it supports multiple OS such as Windows, Mac & Solaris due to which it secured its position in top computer forensics analysis tools. It is incorporated with other free tools such as volatility, autopsy, sleuth kit, etc.

 4. Encase Computer Forensics

EnCase comes under the computer forensics analysis tools developed by Guidance Software. The software is mainly used for digital forensic machine acquisition, imaging, analysis and reporting of the evidence. It generally covers forensic solutions for hard disks, removable media, Smart Phones, Tablets, etc.encase-forensics

The software incorporates a scripting facility EnScript, with various APIs to interact with the evidence. It also features a simple review process to share the artefacts and findings with the investigators. It also gets integrated using its modules to forensics acquisition products such as Tableau. Decryption suites, Image emulators, etc. are all incorporated within the tool. The Toolkit features Registry viewers, Forensic toolkit, Password recovery toolkit and FTK Imager.

5. Volatility

Volatility stands amongst the dedicated tools developed for memory forensics. Helps you take volatile memory dumps, and analyze the digital artefacts from them. It enumerates process lists, network connections, open ports, cached hives, open processes, etc. Supports ram dumps from Windows 7, 8 and also from all the major 32 and 64-bit versions.

Besides the GUI interface, it also provides a command-line version for operating the tool. Features such as adding evidence items, and mounting acquired images using read/write blocked mode extends the user’s capability to perform investigation without tampering with the evidence. It also serves as a HEX viewer/interpreter.

7. Bulk Extractor

Bulk Extractor generally serves the need to scan a forensically acquired disk image and extract viable information from the same. It does not parse the file system or structures as such, but the results obtained from the tool can be easily parsed, and processed with automated tools.
