## Overview
Data exfiltration was a pivotal step preceding the final disruptive attack on the power grid.

### Data Types Exfiltrated
- **Control System Schematics**: Detailed blueprints of the grid's operational infrastructure.
- **Operational Logs**: Logs containing sensitive operational data were extracted.

### Preventative Measures
Deploying advanced anomaly detection systems can help in early identification of data exfiltration activities, thereby safeguarding critical control system data from being compromised.
