Forensic analysis of computer evidence
Digital forensics is the science involved in the discovery, preservation, and analysis of evidence on digital devices. The end goal of digital forensics is to determine the events that occurred, who performed them, and how were they performed. In order for an investigation to lead to a sound …

VADViT:Vision Transformer-Driven Memory Forensics for Malicious Process Detection and Explainable Threat Attribution
… detection, necessitating advanced memory forensic techniques. Machine learning offers potential but struggles with outdated feature sets, large memory data handling, and forensic explainability. To address these challenges, we propose VADViT, a vision-based transformer model that detects …

Formalization Of Input And Output In Modern Operating Systems: The Hadley Model
… associated I/O system as a tool for digital forensic investigators. To illustrate practical uses of the Hadley model we present the Hadley Specification Language, an essentially functional language designed to allow the translations that comprise I/O to be written in a concise format allowing …

An Architecture for Forensic Analysis of Windows System Generated Artefacts
Computer forensic tools have been developed to enable forensic investigators to analyse software artefacts to help reconstruct possible scenarios for activity on a particular computer system. A number of these tools allow the examination and analysis of system generated artefacts such as the …

Computational simulation of skull fracture patterns in pediatric subjects using a porcine model
… it is often the role of the injury biomechanist, forensic pathologist, clinical radiologist, and forensic anthropologist to determine the mechanism of injury when the child victims cannot speak for themselves. This is a challenging task, especially for the head, as comprehensive biomechanical data …

Lead-Free Gunshot Residues as Forensic Evidence
<p>The analysis of gunshot residue (GSR) has been forensically relevant for many years and several methods are well characterized in scientific literature. However, the manufacture and distribution of lead-free alternatives to small caliber firearms ammunition is increasing rapidly as these types …

Determining the impact of carrion decomposition on soil microbial activity levels and community composition.
… locations make them potentially useful for forensic investigators. Advances in microbial profiling techniques have made it possible to compare microbial community profiles obtained from evidence or crime scenes to individuals and vice versa. Profiling microbial communities associated with …

Forensic Discrimination, Age Estimation, and Spectral Optimization For Trace Detection of Blood On Textile Substrates Using Infrared Spectroscopy and Chemometrics
… spectroscopic detection to visualize blood on forensically relevant textiles was evaluated using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). Reflectance spectra of bloodstains contain distinctive amide bands due to the proteins in blood. Amide I, II, and III bands …

A Digital Forensic Readiness Approach for Ransomware Forensics
… infected machine. With the adoption of Digital Forensic Readiness (DFR) processes organizations can better prepare for these types of attacks. DFR provides mechanisms for pro-active collection of digital artifacts. These artifacts play a vital role when a digital investigation is conducted where …

A framework for live forensics
Current techniques used by forensic investigators during incident response and search and seizure operations generally involve pulling the power on suspect machines and performing traditional dead box post-mortem analysis on the persistent storage medium. These cyber-forensic techniques may cause …
