## Lessons Learned

## Recommendations
- **Access Control:** Implement Phishing-resistant MFA for all internal administrative systems.
- **Data Minimization:** Review data retention policies to ensure historical order data is encrypted or archived off-site when no longer needed for active operations.
- **Monitoring:** Deploy User and Entity Behavior Analytics (UEBA) to detect anomalous data access patterns in the backend of the e-commerce platform.
- **Phishing Awareness:** Provide customers with clear guidelines on how the brand will and will not communicate to mitigate the risk of "perpetrator" follow-up attacks.
