Overview
Hands-on experience in ransomware incident response and disaster recovery, from containment and eradication to full restoration of business-critical services.
Incident Response Framework
1. Containment & Isolation
- Isolated network perimeter to stop ransomware encryption spread
- Preserved logs and analyzed entry point for forensic investigation
2. Eradication & Rebuild
- Complete wiping and reinstallation of 20 VMware ESXi nodes
- Security hardening (hardening) on new ESXi hosts
3. Recovery & Restoration
- Restored data from verified clean Veeam backups
- Ensured data integrity before restoring to production
4. Post-Incident
- Security policy evaluation and recommendations
- Preventive measures for future incidents
Key Learnings
- Verified clean backups are critical — test restore procedures regularly
- Network segmentation limits ransomware spread
- Documentation and runbooks speed up recovery time
- Veeam with immutable backups provides reliable recovery point
