Insight:an application of information visualisation techniques to digital forensics investigations
As digital devices are becoming ever more ubiquitous in our day to day lives, more of our personal information and behavioural patterns are recorded on these devices. The volume of data held on these devices is substantial, and people investigating these datasets are facing growing backlog as a result. This is worsened by the fact that many software tools used in this area are text based and do not lend themselves to rapid processing by humans.This body of work looks at several case studies in which these datasets were visualised in attempt to expedite processing by humans. A number of different 2D and 3D visualisation methods were trialled, and the results from these case studies fed into the design of a final tool which was tested with the assistance of a group of individuals studying Digital Forensics.The results of this research show some encouraging results which indicate visualisation may assist analysis in some aspects, and indicates useful paths for future work
EviPlant: An efficient digital forensic challenge creation, manipulation and distribution solution
Education and training in digital forensics requires a variety of suitable
challenge corpora containing realistic features including regular
wear-and-tear, background noise, and the actual digital traces to be discovered
during investigation. Typically, the creation of these challenges requires
overly arduous effort on the part of the educator to ensure their viability.
Once created, the challenge image needs to be stored and distributed to a class
for practical training. This storage and distribution step requires significant
time and resources and may not even be possible in an online/distance learning
scenario due to the data sizes involved. As part of this paper, we introduce a
more capable methodology and system as an alternative to current approaches.
EviPlant is a system designed for the efficient creation, manipulation, storage
and distribution of challenges for digital forensics education and training.
The system relies on the initial distribution of base disk images, i.e., images
containing solely base operating systems. In order to create challenges for
students, educators can boot the base system, emulate the desired activity and
perform a "diffing" of resultant image and the base image. This diffing process
extracts the modified artefacts and associated metadata and stores them in an
"evidence package". Evidence packages can be created for different personae,
different wear-and-tear, different emulated crimes, etc., and multiple evidence
packages can be distributed to students and integrated into the base images. A
number of additional applications in digital forensic challenge creation for
tool testing and validation, proficiency testing, and malware analysis are also
discussed as a result of using EviPlant.Comment: Digital Forensic Research Workshop Europe 201
"Цифровой эксгибиционизм": самоидентификация личности в условиях информационного общества
В статье рассматривается влияние интенсивного развития информационных и коммуникационных
технологий на личность и восприятие ею своего места в социуме. Авторы обращаются к ключевым вопросам, обусловленным особенностью современной жизни - непосредственной связью с сетью Интернет: как воспринимается человеческое тело в виртуальном мире, что значит для человека постоянное присутствие в сети, так ли безопасен виртуальные мир для человека по эту сторону экран
Analysing and Carving MS Word and PDF Files from RAM Images on Windows
In this study, a piece of software has been developed to recover the readable data by carving MS Word and PDF files from the RAM image. String searching, signature scanning, and data carving methods are used in the design of the software. The analysis was performed on a RAM image of 14 GB by using the software that was developed. The success rate for each file was determined by comparing the recovered data to the data in the original file. It was determined that the rate of data recovery decreases as the size of the MS Word or PDF files loaded onto RAM increases. Consequently, it is aimed to be an important example of obtaining electronic evidence from volatile data in forensic informatics with the proposed study
