AI-Driven Cyber Threats and National Cyber Resilience: Comparative Cybersecurity Challenges in Italy and Nigeria

Artificial Intelligence (AI) is rapidly transforming global digital ecosystems, economic systems, and organizational operations. However, the increasing integration of AI technologies into interconnected digital infrastructures has simultaneously expanded the global cyber threat landscape. AI-driven phishing campaigns, deepfake-enabled fraud, automated reconnaissance, synthetic identity manipulation, and attacks targeting critical infrastructure systems are emerging as major cybersecurity concerns affecting both developed and developing economies.

This paper comparatively examines the evolving AI-driven cybersecurity challenges confronting Italy and Nigeria. Italy, as a technologically advanced European nation with relatively mature cybersecurity governance structures, faces increasing exposure to ransomware, industrial cyberattacks, geopolitical cyber operations, and attacks targeting critical infrastructure systems. Nigeria, meanwhile, continues to experience rapid digital expansion across fintech, telecommunications, cloud services, e-governance, and digital financial systems, resulting in increasing vulnerability to financial cybercrime, identity fraud, ransomware, and data protection challenges.

The study explores how Artificial Intelligence is accelerating the sophistication, scalability, accessibility, and operational effectiveness of cyberattacks while simultaneously exposing governance gaps, regulatory weaknesses, and infrastructure vulnerabilities. The paper further proposes technical, governance, and policy recommendations aimed at strengthening national cyber resilience, improving AI governance, and protecting critical infrastructure systems.

The paper argues that cybersecurity must increasingly be viewed not solely as a technical issue, but as a matter of national resilience, economic protection, digital sovereignty, governance, and strategic security within the emerging AI era.
