This study examined the direct effect of brainstorming on fraud risk assessment at credit card issuing banks in Indonesia. Therefore, it was expected to help improve their performance in dealing with various credit card frauds. This study involved 80 participants from the credit card fraud risk management team from four major credit card issuing banks in Indonesia, consisting of the risk management team (anti-fraud specialist) and the internal auditor team. The research was analyzed using the experimental method with a 2X1 factorial design. Analysis of Variance (ANOVA) would test the experimental data. The individuals’ performance (without brainstorming) or the brainstorming group was analyzed using the statistical ANOVA technique. ANOVA analysis produced a sig value of less than 1% and an F-count of 50.556 > 0.143443, which was higher than the F-table. The ANOVA test results concluded that there were differences in assessing the fraud between the respondents with brainstorming and those without it. Through the brainstorming method, it turned out that the respondents in the fraud risk management team provided a more accurate credit card fraud risk assessment from the point of view of the fraud causes and the credit card fraud impacts.
Hence, it is crucial for credit card issuing banks in Indonesia to consistently implement anti-fraud governance by adopting brainstorming to produce a better fraud risk assessment.

The increase in online credit card transactions in the digital era has caused an increase in credit card cyber incidents. This is happening globally, including in Indonesia. Thus, it will affect a bank’s reputation as well as its financial losses. Therefore, optimal fraud risk management is needed in a banking effort to prevent credit card fraud. In response, this article intended to study credit card fraud prevention by examining the relationship between digital security required for customer data security; fraud brainstorming to identify process weaknesses; and compliance management to manage regulatory compliance. The next step was to test whether the anti-fraud specialist is competent to moderate this relationship. This study used a quantitative approach. This study included 27 Indonesian card issuers. Primary sources were used to collect data for this study. The primary data were analyzed using a structural equation model (SEM). The results of the study show that digital security, fraud brainstorming, and compliance management were positively and significantly related to the prevention of credit card fraud, at a significance level of 5%, the t-statistic has a numerical value of 6.161, 5.079, and 5.98 each. Furthermore, testing the moderating effect obtained t-statistic values of 7.330, 4.161, and 7.694. Competency results obtained with positive and significant influence moderate the relationship between these factors and credit card fraud prevention. These findings have policy implications for banking and government objectives in fighting credit card fraud through implementing prevention strategies.
