Cybercrime has become a growing concern in Nigeria’s banking sector, with increasing incidents of phishing, data breaches, and online fraud threatening financial stability and customer trust. As banks digitize operations, the need for robust detection mechanisms becomes more urgent. Forensic accounting techniques such as Computer-Assisted Audit Tools (CAATs), digital forensics, and structured forensic investigation procedures have emerged as valuable tools in combating these evolving threats. The main objective of this study is to examine the effect of forensic accounting techniques on cybercrime detection among listed deposit money banks in Nigeria. Specifically, it investigates the roles of CAATs, digital forensic tools, and forensic investigation methods in curbing cyber-related financial crimes. The study adopts a survey research design. Primary data were collected from staff and management of ten purposively selected listed banks using structured questionnaires. The data were analyzed using both descriptive statistics and inferential methods, including correlation and regression analysis. Findings reveal that all three forensic accounting techniques have significant positive effects on cybercrime detection, with digital forensic tools having the strongest impact. The results confirm that forensic accounting enhances cybercrime prevention through proactive detection, evidence gathering, and system monitoring. Based on these findings, the study recommends that banks invest in advanced digital forensic infrastructure, strengthen cybercrime tracking systems, and institutionalize internal forensic investigation protocols. These efforts will help reduce cyber-related risks and improve the resilience of Nigeria’s financial system.
