In a recent analysis of the current cyber threat landscape, a financial institution identified a significant increase in ransomware attacks targeting their customer data. The institution\'s security team is tasked with assessing the potential impact of these attacks on their operations and customer trust. Given that the average cost of a ransomware attack is estimated to be $200,000, and the institution has 50,000 customers, what would be the potential financial impact per customer if the institution were to experience a ransomware attack? Additionally, consider the long-term effects on customer trust and regulatory compliance, which could lead to a 15% decrease in customer retention over the next year. What is the total estimated financial impact per customer, including both immediate costs and potential loss of revenue from decreased customer retention?
