Small and Medium-sized Enterprises (SMEs) face disproportionately high risks from Advanced Persistent Threats (APTs), which often evade traditional cybersecurity measures. Existing frameworks catalogue adversary tactics and defensive solutions but pr...
The widespread dissemination of misleading news presents serious challenges to public discourse, democratic institutions, and societal trust. Misleading-news classification (MNC) has been extensively studied through deep neural models that rely mainl...
Privacy harms have expanded alongside rapid technological change, challenging the adequacy of existing regulatory frameworks. This systematic review (1990–2025) systematically maps documented privacy harms to specific legal mechanisms and obser...
Phishing attacks, particularly Smishing (SMS phishing), have become a major cybersecurity threat, with attackers using social engineering tactics to take advantage of human vulnerabilities. Traditional detection models often struggle to keep up with...
This review examines AI governance centered on Regulation (EU) 2024/1689 of the European Parliament and of the Council of 13 June 2024 laying down harmonised rules on artificial intelligence (the EU Artificial Intelligence Act), alongside comparable...
This article analyzes how artificial intelligence (AI) is influencing the evolution of cybercrime in Ecuador. The use of AI tools to create new threats, such as intelligent malware, automated phishing, and financial fraud, is on the rise. The main pr...
This study examines the adoption and implementation of the Zero Trust (ZT) cybersecurity paradigm using the Technology–Organization–Environment (TOE) framework. While ZT is gaining traction as a security model, many organizations struggle...
Malware remains one of the most persistent and evolving threats to cybersecurity, necessitating robust analysis techniques to understand and mitigate its impact. This study presents a comprehensive analysis of selected malware samples using both stat...
The implementation of the NIS2 Directive expands the scope of cybersecurity regulation across the European Union, placing new demands on both essential and important entities. Despite its importance, organizations face multiple barriers that undermin...
Ransomware attacks pose a serious threat to computer networks, causing widespread disruption to individual, corporate, governmental, and critical national infrastructures. To mitigate their impact, extensive research has been conducted to analyze ran...
The increasing volume, velocity, and sophistication of cyber threats have placed immense pressure on modern Security Operations Centers (SOCs). Traditional rule-based and manual processes are proving insufficient, leading to alert fatigue, delayed re...
Mobile networking in 4G and 5G remains vulnerable against fake base stations. A fake base station can inject and manipulate the radio resource control (RRC) communication protocol to disable the user equipment’s connectivity. To motivate our re...
The rapid digitalization of work and daily life has introduced a wide range of online threats, from common hazards such as malware and phishing to emerging challenges posed by artificial intelligence (AI). While technical aspects of cybersecurity hav...
Hashes are vital in limiting the spread of child sexual abuse material online, yet their use introduces unresolved technical, legal, and ethical challenges. This paper bridges a critical gap by analyzing both cryptographic and perceptual hashing, not...
Email continues to serve as a primary vector for cyber-attacks, with phishing, spoofing, and polymorphic malware evolving rapidly to evade traditional defences. Conventional email security systems, often reliant on static, signature-based detection s...
The rapid expansion of the Internet of Things (IoT) has introduced new vulnerabilities that traditional security mechanisms often fail to address effectively. Signature-based intrusion detection systems cannot adapt to zero-day attacks, while rule-ba...
Digital banking has become part of everyday life in Aotearoa–New Zealand, offering convenience but also raising questions of trust, security, and long-term commitment. This study examines how service quality, security and privacy, user experien...
This paper introduces a novel similarity measure to link transactions which spend outputs of CoinJoin transactions, CoinJoin Spending Transactions (CSTs), by analyzing their on-chain properties, addressing the challenge of preserving user privacy in...
Generative artificial intelligence (AI) and persistent empirical gaps are reshaping the cyber threat landscape faster than Zero-Trust Architecture (ZTA) research can respond. We reviewed 10 recent ZTA surveys and 136 primary studies (2022–2024)...
Hardware systems are foundational to critical infrastructure, embedded devices, and consumer products, making robust security assurance essential. However, existing hardware security standards remain fragmented, inconsistent in scope, and difficult t...
Intrusion Detection Systems (IDS) play a vital role in safeguarding networks, yet their effectiveness is often challenged, as cyberattacks evolve in new and unexpected ways. Machine learning models, although very powerful, usually perform well only o...
The General Data Protection Regulation (GDPR) imposes additional demands and obligations on service providers that handle and process personal data. In this paper, we examine how advanced cryptographic techniques can be employed to develop a privacy-...
This study proposes methods of computer simulation to study and optimize the cybersecurity of Small Modular Nuclear Reactors (SMRs). SMRs hold the potential to help build a clean and sustainable power grid but will struggle to gain widespread adoptio...
Known attacks on the tropical implementation of Stickel protocol involve finding minimal covers for a certain covering problem, and this leads to an exponential growth in the worst case time required to recover the secret key as the used polynomial d...
This study investigates the evolution of cybercrime in Greece by analyzing data from the Cyber Crime Division of the Hellenic Police. By combining 2023 statistics with earlier national and international data (e.g., Europol, FBI), this study presents...
