Issue 21 examines foundational and emerging challenges across digital forensics, including SQLite-based artefact reconstruction, large-scale image-recovery analytics, memory-resident cryptographic key extraction, and security concerns within cyber-physical systems. Additional research addresses IPv6 tunnelling vulnerabilities, security-analytics evolution, email-security modernisation, APT-resilience strategies, and narrative framing for cyber-physical adoption, with legal and laboratory features expanding practice-ready investigative and evidential methodologies.

Issue 20 examines volatile-memory credential recovery, steganography detection in audio streams, and cross-device data exchange through hydrological-cycle analogies. Features explore convergence between IT security and physical access control, governance of privileged permissions, and psychological influences on user behaviour. Articles further address critical-infrastructure security attributes, ZFS-based super-timelines, and the emergence of the Cyber Scheme, alongside legal and laboratory insights into mobile-device investigations.

Issue 19 spans core cyber-skills development, emerging attack vectors, and platform-specific vulnerabilities, while advancing practice-ready methodologies for volatile-memory credential recovery, mobile-device investigation, and wearable-technology forensics. Themes include human-factor security, automation for capability uplift, watermarking for intellectual-property protection, and maturing incident-response functions. Legal and laboratory features analyse EU cyber-crime initiatives and evolving investigative tooling across increasingly multimedia-rich evidential environments.

Issue 18 explores practitioner-focused advances in malware correlation using fuzzy hashing, DFIR temporal reasoning through Anchors in Relative Time, and Android security weaknesses relevant to exploitation and investigation. It examines GPS accuracy implications for evidential reliability, organisational forensic-readiness planning, and analytics-driven fraud prevention. The issue also highlights evolving cyber-skills requirements and lab perspectives on mobile-forensics tool integration.

Issue 17 examines practitioner challenges across cyber-physical security, SCADA honeypot deployment, and first-responder methodologies for cyber-terror incidents. It assesses NIDS-derived evidential acquisition, iPhone-backup artefact recovery, and secure-erasure tool reliability. The issue also explores offensive–defensive insights from OSINT-driven reconnaissance, discusses sector perspectives from DF professionals, and highlights evolving competencies required for forensically sound operations across industrial and enterprise environments.
