Globally, fraud is one of the most significant factors that negatively affect the performance of public servants. Therefore, the primary purpose of this study was to investigate the impact of training and development, autocratic leadership, social media strategy, and learning management systems on employee attitude and performance with the intervention of an internal control system as anti-fraud oversight. This study also investigated the mediating role of anti-corruption attitudes and the moderating role of internal control as anti-fraud oversight. This research was quantitative and cross-sectional in nature. The civil servants of Indonesia were surveyed using a questionnaire based on previous research. The study’s valid response rate was 76.19 percent. Using Smart PLS 3.3.9, the data were examined. The study’s findings indicate that learning management system, social media marketing campaign, autocratic leadership, and training and development significantly impact corruption prevention attitudes. In addition, the results support the moderating role of internal control as anti-fraud oversight and the mediating role of attitude. These findings are useful for academicians conducting future research and policymakers devising strategies to enhance the performance of government employees.
