## Lessons Learned
- The compromise of a centralized customer management system poses a critical risk due to the high volume and sensitivity of the aggregated data.
- Access controls and segmentation around core customer databases/management systems must be rigorously maintained to prevent unauthorized access leading to mass exfiltration.
## Recommendations
- Conduct an immediate, deep forensic investigation to determine the exact initial access vector and the methods used to maintain access.
- Review and strengthen authentication and authorization mechanisms for the customer management system, potentially enforcing stricter Multi-Factor Authentication (MFA).
- Enhance monitoring and alerting on bulk data queries or unusual exports from customer data repositories.
- Develop and execute a communication plan addressing the exposed data types (especially bank and government ID numbers) for the 6.2 million affected individuals.
