Ransomware attacks are escalating, and organizations must be prepared to respond swiftly. The Virtual Ransomware Fire Drill Workshop by Druva offers hands-on simulations to test and improve recovery strategies.
You Should Know:
1. Pre-Recovery Preparation
- Backup Verification: Ensure backups are immutable and offline.
Check backup integrity (Linux) sha256sum /backup/path/backup_file.tar.gz
- Isolate Infected Systems:
Isolate a compromised Linux host from the network sudo iptables -A INPUT -j DROP
2. Incident Response Commands
- Identify Ransomware Processes (Windows):
Get-Process | Where-Object { $_.CPU -gt 90 } | Stop-Process -Force - Check Suspicious Files (Linux):
find / -type f -name ".encrypted" -o -name ".locky"
3. Recovery Steps
- Restore from Backup (Linux):
tar -xzvf /backup/path/clean_backup.tar.gz -C /restore/location
- Windows System Restore:
wbadmin start recovery -version:01/01/2025-10:00 -itemType:File -items:C:\
4. Post-Recovery Hardening
- Disable RDP if Not Needed (Windows):
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\Terminal Server" -Name "fDenyTSConnections" -Value 1
- Enable Fail2Ban (Linux):
sudo apt install fail2ban sudo systemctl enable --now fail2ban
5. Log Analysis for Root Cause
- Check Auth Logs (Linux):
grep "Failed password" /var/log/auth.log
- Windows Event Logs:
Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4625}
What Undercode Say:
Ransomware recovery isn’t just about restoring data—it’s about minimizing downtime and preventing reinfection. Regular fire drills, immutable backups, and automated threat detection (e.g., YARA rules, SIEM alerts) are critical.
Prediction:
Ransomware will increasingly target cloud backups, forcing organizations to adopt air-gapped and zero-trust backup solutions.
Expected Output:
- Immutable backups verified.
- Infected systems quarantined.
- Critical services restored within RTO.
