A Critical Analysis of Cybercrime Trends in Nigeria (2018–2025): Patterns, Drivers, and Policy Responses

Abstract

The digital transformation of Nigeria's economy over the past decade has been accompanied by a parallel escalation in cybercriminal activity, presenting complex challenges for policymakers, law enforcement agencies, and citizens alike. This study examines the evolution of cybercrime trends in Nigeria between 2018 and 2025, with attention to the shifting modus operandi of cybercriminals, the socioeconomic and technological drivers facilitating these offences, and the adequacy of institutional and legislative responses. The period witnessed a marked transition from crude advance-fee fraud schemes toward sophisticated tactics including business email compromise, ransomware attacks on corporate and governmental networks, and the weaponization of social media platforms for sextortion and cyberbullying. Financial sector losses attributed to cyber-enabled fraud exceeded ₦56 billion between 2021 and 2024, though underreporting suggests the actual figure may be substantially higher. The study identifies key drivers including the expanding attack surface created by rapid mobile money adoption, persistent infrastructural deficits in digital forensic capabilities, and the emergence of transnational organized criminal networks operating within and beyond Nigeria's borders. Policy responses examined include the Cybercrimes (Amendment) Act 2024, the establishment of the Nigeria Data Protection Commission, and institutional coordination mechanisms such as the Joint Case Team on Cybercrimes. The findings suggest that while legislative frameworks have strengthened considerably, implementation deficits, capacity constraints, and limited international cooperation continue to impede effective cybercrime control. The study recommends enhanced investment in digital forensic infrastructure, mandatory cybersecurity curricula at tertiary institutions, and the development of a comprehensive national cybersecurity strategy aligned with evolving threat landscapes
