## Recommendations
- **Prevention measures:** Implement robust Attack Surface Management (ASM) to identify exposed entry points.
- **Data Security:** Encrypt sensitive data at rest and implement strict network segmentation to isolate files containing SSNs.
- **Access Control:** Enforce Multi-Factor Authentication (MFA) across all institutional accounts to prevent unauthorized lateral movement.
