Abstract

Nigerian financial technology firms have expanded their forensic tooling, analyst teams, and investigative routines, yet fraud losses have continued to climb, exposing a gap between the capability firms hold and the detection they achieve. This study examined the moderating effect of cybersecurity culture on the relationship between digital forensic investigation competence and cyber-fraud detection effectiveness among FinTech firms in Nigeria. From an accessible population of 140 licensed FinTech firms supervised by the Central Bank of Nigeria and affiliated with the FinTech Association of Nigeria, each represented by a principal officer responsible for cyber-fraud and digital-forensic functions, a sample of 103 was drawn using the Taro Yamane formula and purposive selection. Primary data from a structured five-point Likert questionnaire were analysed through partial least squares structural equation modelling (PLS-SEM) in SmartPLS. The measurement model satisfied indicator reliability, internal consistency, and convergent validity, and discriminant validity held under both the Fornell-Larcker criterion and the HTMT ratio. Digital evidence analysis capability (β=0.284, p < 0.001), digital forensic tools sophistication (β=0.221, p < 0.01), and digital forensic personnel expertise (β=0.318, p < 0.001) each raised detection effectiveness, with personnel expertise the strongest antecedent. Cybersecurity culture strengthened the competence-todetection relationship as a moderator (β =0.149, p < 0.05) and acted directly on detection (β=0.196, p < 0.05). Forensic investment pays its fullest dividend only where security culture is strong enough to put it to work. The study recommends targeted development of forensic personnel, deliberate cultivation of security culture, and continual renewal of the forensic toolset.
