### Summary
APT40 has successfully moved laterally within the network, gaining access to secure data sources including databases containing sensitive maritime research.

### Lateral Movement Tactics
- **Credential Stuffing**: Utilization of harvested credentials to access different network segments.
- **Remote Desktop Protocol (RDP)**: Exploiting RDP to move between systems and access secured data.

### Next Steps
Prepare for potential data exfiltration activities by analyzing network logs for large outbound data transfers, especially focusing on sonar technology schematics.
