Abstract

Cybercrime poses significant risks to the banking sector through operational disruptions, data breaches, declining public trust, and increased recovery costs. In Islamic banking, these risks are particularly important because customer confidence and institutional integrity are closely linked to ethical and Shariah principles. Despite growing concerns over cyber resilience, empirical evidence on annual financial performance following major cyber incidents in Islamic banking remains limited, particularly from a CAMEL-based perspective. This study addresses this gap by assessing the annual financial resilience of Bank Syariah Indonesia (BSI), comparing the pre-incident fiscal year (2022) with the incident year (2023) using audited consolidated financial statements and a comparative case study approach. The analysis focuses on cumulative annual financial performance rather than short-term post-attack effects. The findings show that observed financial indicators did not deteriorate overall during the incident year: the capital adequacy ratio (CAR) increased from 20.29% to 21.04%, non-performing financing (NPF) decreased from 2.42% to 2.08%, and return on assets (ROA) increased from 1.98% to 2.35%. The Financing-to-Deposit Ratio (FDR) also increased from 79.37% to 81.73%, while information technology investment increased by 263%, from IDR 266 billion to IDR 968 billion. Overall, the findings indicate that annual financial soundness was maintained during the incident year, while the observed changes coincided with increased IT investment. These patterns should be interpreted as descriptive associations, as annual financial performance may also reflect broader economic conditions, institutional factors, and managerial decisions.
