Using Ruby to Recover JPEGs from a Forensic Image

This is the second post in a series investigating different programming languages applied to a forensics recovery problem. More detail about the problem can be found in Using Go to Recover JPEGs from a Forensic Image. The code is available on GitHub. Continuing from the last post the next language I looked at was Ruby. As a brief recap, the problem was to recover 16 JPEG files from a forensic image which had been zero wiped before they were taken. About Ruby Ruby is a language that was popularised by the web framework Ruby on Rails. It can be best surmised by the quote…

Using Go to Recover JPEGs from a Forensic Image

CS50 is an introductory course offered by Harvard to students at the college and online via EdX and the Harvard Extension School. It teaches mostly through a series of problems sets which mostly focus on using C to solve them. One of the more interesting problem sets is Problem Set 4: Forensics. The Problem The original problem was solved in C as part of the course and here will be solved using Go. But before looking at any code it is important to give a little context (all code is available on GitHub for those that are interested). Key characteristics of the problem have been outlined below: What we…
