## Lessons Learned

## Recommendations
- Conduct a thorough forensic investigation to definitively determine all systems accessed and data potentially exfiltrated.
- Review and enhance access controls and monitoring specifically related to critical organizational servers.
- Re-assess segmentation between corporate/office networks and clinical/operational technology environments to prevent future internal sprawl.
