Abstract
Financial systems in East Africa are increasingly interconnected through digital platforms, exposing them to cybersecurity risks such as cyber-attacks and data breaches. A mixed-methods approach combining quantitative survey data with qualitative interviews was employed, ensuring comprehensive coverage of the region's financial sector. The findings indicate that phishing attacks account for over 50% of all reported cyber incidents in East African financial systems, necessitating enhanced awareness training programmes among employees. Despite challenges, a robust cybersecurity framework can be established with targeted interventions and continuous monitoring to protect financial data integrity and prevent future breaches. Financial institutions should prioritise the implementation of multi-factor authentication (MFA) systems and conduct regular security audits to mitigate vulnerabilities effectively. Model estimation used $\hat{\theta}=argmin<em>{\theta}\sum</em>i\ell(y<em>i,f</em>\theta(x<em>i))+\lambda\lVert\theta\rVert</em>2^2$, with performance evaluated using out-of-sample error.
