Cybersecurity incidents and data breaches are increasingly common and pose significant financial risks for firms. This study examines how consumers respond to major data breach announcements and evaluates their economic consequences for affected companies. Using a difference-in-differences research design, we analyze a large-scale data breach in the hospitality industry that exposed over 380 million customer records. The results show a short-term decline in the firm's revenue following the breach disclosure, lasting approximately two months before recovering. These findings suggest that while data breaches initially affect consumer behavior, long-term financial consequences may be more limited than commonly assumed, potentially due to consumers' limited attention to privacy concerns.
