### Contextual Overview
With valid credentials, attackers executed lateral movement strategies to access critical SCADA systems, key components in the power grid infrastructure.

### Technical Insight
Attackers mapped the network using tools like PsExec and leveraged remote desktop services to gain access to SCADA systems. This movement was facilitated by stolen credentials and undetected due to legitimate-looking access patterns.

### Mitigation Strategies
- **Network Segmentation**: Implement strict network segmentation to isolate critical infrastructure components.
- **Access Controls**: Enforce the principle of least privilege and implement robust access controls.

### Next Steps
Prepare for potential destructive actions, including the deployment of the KillDisk wiper, to understand its impact and recovery strategies.
