With ransomware attacks becoming increasingly common, organizations must prepare for rapid recovery. The Virtual Ransomware Fire Drill Workshop by Druva offers hands-on simulations to test and improve incident response strategies.
You Should Know:
1. Pre-Workshop Preparation (Linux/Windows Commands)
- Check Backup Integrity (Linux):
tar -tzf backup.tar.gz | grep "critical_files" sha256sum backup.tar.gz
- Verify Windows Shadow Copies:
vssadmin list shadows
2. Simulate Ransomware Attack (Testing Isolation)
- Linux (Isolate Compromised Host):
iptables -A INPUT -s <infected_IP> -j DROP systemctl stop smbd nmbd Stop Samba shares
- Windows (Disconnect Network):
netsh interface set interface "Ethernet" disable
3. Recovery Steps (File Restoration)
- Linux (Restore from Backup):
rsync -avz /backup/latest/ /production/ chmod -R 750 /production/ Lock down permissions
- Windows (Use Volume Shadow Copy):
wmic shadowcopy call create Volume='C:\'
4. Post-Action Forensics (Log Analysis)
- Linux (Check Suspicious Processes):
journalctl -u sshd --no-pager | grep "Failed" lsof -i :445 Check Samba connections
- Windows (Extract IOC’s from Event Logs):
Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4625}
Prediction:
Ransomware will increasingly target hybrid cloud environments, requiring automated backup validation and zero-trust segmentation.
What Undercode Say:
Proactive drills like Druva’s workshop are critical. Combine them with hardened backups (immutable storage), network segmentation, and endpoint detection (EDR) to minimize downtime.
Expected Output:
- Verified backup integrity logs.
- Isolated network traffic reports.
- Restored file checksums.
- Forensic timeline of attack.
