SUMURI Hex Viewer

SUMURI Hex Viewer is a Windows-based hex editor software application.  It was purpose built for teaching disk structures and file systems in IACIS classes. It is freely available to all IACIS members. 

The SUMURI Hex Viewer offers all the features needed when learning disk level forensics. Features include: 

  • Opening any file including forensic image files and physical disks  
  • Support for several forensic image formats including DD, E01 and VHD  
  • Navigating through loaded data by jumping to absolute or relative offsets in bytes or multiples of bytes (such as sectors or clusters)  
  • Highlighting strings of bytes in a hexadecimal view and interpreting the selected data as 8/16/24/32/64 bit signed or unsigned integers, DOS/Unix/Windows/Mac dates and times, and GUID values 
  • Tagging strings of bytes in a hexadecimal view by applying a custom background colour and a descriptive label 
  • Built-in highlighting templates for popular disk structures and filesystems including MBR, GPT, FAT, NTFS and ExFAT 
  • Support for user-created custom templates

The SUMURI Hex Viewer was developed in response to a challenge faced by the IACIS training committee.  Training required an affordable Hex Editor to provide to students in the Basic Computer Forensic Examiner (BCFE) class, to be used to learn about disk structures and file systems and what goes on under the hood.  SUMURI graciously volunteered their skills and expertise in software development and worked closely with the training committee through many iterations to build the SUMURI Hex Viewer software application.This software made its debut in the BCFE classroom at the 2022 Training Event in Orlando, Florida, USA.  It was well received and a great success and as such it is now a mainstay of IACIS training and a critical piece of the learning experience.

This project highlights again that SUMURI is a wonderful supporter of IACIS and its mission.
