Fast Forensic Triage Using Centralised Thumbnail Caches On Windows Operating Systems, Sean Mckeown, Gordon Russell, Petra Leimich Sep 2019

Fast Forensic Triage Using Centralised Thumbnail Caches On Windows Operating Systems, Sean Mckeown, Gordon Russell, Petra Leimich

Journal of Digital Forensics, Security and Law

A common investigative task is to identify known contraband images on a device, which typically involves calculating cryptographic hashes for all the files on a disk and checking these against a database of known contraband. However, modern drives are now so large that it can take several hours just to read this data from the disk, and can contribute to the large investigative backlogs suffered by many law enforcement bodies. Digital forensic triage techniques may thus be used to prioritise evidence and effect faster investigation turnarounds. This paper proposes a new forensic triage method for investigating disk evidence relating to …


Improved Decay Tolerant Inference Of Previously Uninstalled Computer Applications, Oluwaseun Adegbehingbe, James Jones Sep 2019

Improved Decay Tolerant Inference Of Previously Uninstalled Computer Applications, Oluwaseun Adegbehingbe, James Jones

Journal of Digital Forensics, Security and Law

When an application is uninstalled from a computer system, the application’s deleted file contents are overwritten over time, depending on factors such as operating system, available unallocated disk space, user activity, etc. As this content decays, the ability to infer the application’s prior presence, based on the remaining digital artifacts, becomes more difficult. Prior research inferring previously installed applications by matching sectors from a hard disk of interest to a previously constructed catalog of labeled sector hashes showed promising results. This prior work used a white list approach to identify relevant artifacts, resulting in no irrelevant artifacts but incurring the …

This type of evidence is routinely produced as business records under U.S. Federal Rules of Evidence for use in the emerging discipline of Forensic Cell Site Analysis. The research was undertaken to determine if evidence produced by operators should be classified as digital evidence and, if so, what evidence handling methodologies are appropriate to ensure evidence integrity. This research project resulted in the creation of a method of determining if business records produced by MNO/MVNO organizations are digital evidence and …


Examining The Correlates Of Failed Drdos Attacks, Thomas Hyslip, Thomas Holt Jun 2019

Examining The Correlates Of Failed Drdos Attacks, Thomas Hyslip, Thomas Holt

Journal of Digital Forensics, Security and Law

Over the last decade, there has been a rise in cybercrime services offered on a feefor- service basis, enabling individuals to direct attacks against various targets. One of the recent services offered involves stresser or booter operators, who offer distributed reflected denial of service (DRDoS) attacks on an hourly or subscription basis. These attacks involve the use of malicious traffic reflected off of webservers to increase the volume of traffic, which is directed toward websites and servers rendering them unusable. Researchers have examined DRDoS attacks using realtime data, though few have considered the experience of their customers and the factors …

Journal of Digital Forensics, Security and Law

The current state of digital forensic investigation is continuously challenged by the rapid technological changes, the increase in the use of digital devices (both the heterogeneity and the count), and the sheer volume of data that these devices could contain. Although data privacy protection is not a performance measure, however, preventing privacy violations during the digital forensic investigation, is also a big challenge. With a perception that the completeness of investigation and the data privacy preservation are incompatible with each other, the researchers have provided solutions to address the above-stated challenges that either focus on the effectiveness of the investigation …

Revolution In Crime: How Cryptocurrencies Have Changed The Criminal Landscape, Igor Groysman Dec 2018

Revolution In Crime: How Cryptocurrencies Have Changed The Criminal Landscape, Igor Groysman

Student Theses

This thesis will examine the ways in which various cryptocurrencies have impacted certain traditional crimes. While crime is always evolving with technology, cryptocurrencies are a game changer in that they provide anonymous and decentralized payment systems which, while they can be tracked in a reactive sense via the blockchain, are seen by criminals as having better uses for them than traditional fiat currencies, such as the ability to send money relatively fast to another party without going through an intermediary, or the ability to obscure the origin of the money for money laundering purposes. Every week there are new cryptocurrencies …
