## Lessons Learned
- **Key Takeaways:** Cloud-hosted storage remains a high-value target for external actors; timely identification of suspicious activity is critical, even if the full scope of the breach takes longer to verify.
- **What could have been done better:** The gap between the initial incident (February) and the formal "Discovery Date" (April) suggests a need for more streamlined data review processes to identify impacted subjects faster.
## Recommendations
- **IAM Hardening:** Implement strict Identity and Access Management (IAM) policies and Multi-Factor Authentication (MFA) for all cloud storage administrative roles.
- **Encryption:** Ensure all sensitive data stored in the cloud is encrypted at rest and in transit.
- **Monitoring:** Enhance logging and alerting for "suspicious activity" within cloud environments (e.g., unusual egress volumes or access from unrecognized IPs).
- **Audit:** Conduct regular security audits of third-party cloud-hosted platforms.
