### Overview
Unauthorized access to internal networks has been detected, indicating the attackers are moving laterally to compromise additional systems.

### Technical Details
- **Compromised Credentials**: Attackers are using stolen credentials to access network resources.
- **Network Traffic**: Unusual traffic patterns suggest data is being accessed from multiple endpoints.

### Recommendations
- **Network Segmentation**: Implement network segmentation to restrict lateral movement.
- **Credential Management**: Enforce strong password policies and multi-factor authentication.

### Next Steps
Focus on detecting and preventing data exfiltration, as attackers are likely to attempt data theft via encrypted channels.
