### Context and Analysis

Evidence of lateral movement within the network has been detected. The adversaries are leveraging compromised credentials to access sensitive areas of the network, specifically targeting documents and communications related to nuclear policy.

### Recommendations
- **Immediate Action:** Revoke compromised credentials and enforce a network-wide password reset.
- **Network Segmentation:** Implement tighter access controls and segment sensitive data to limit unauthorized access.

### Next Steps
Prepare for potential data exfiltration attempts by enhancing monitoring of outgoing traffic and securing data transfer protocols.
