Ransomware attacks are escalating, and organizations must be prepared to respond swiftly. The upcoming Virtual Ransomware Fire Drill Workshop by Druva offers hands-on simulations to test and improve recovery strategies. Below, we dive into practical steps, commands, and tools to strengthen your ransomware defense and recovery.
You Should Know:
1. Pre-Recovery Preparation (Linux/Windows Commands)
- Backup Verification (Linux):
List and verify backup files ls -lah /backup/ sha256sum /backup/critical_data.tar.gz
- Windows Shadow Copy Check:
List available shadow copies vssadmin list shadows
2. Isolate Infected Systems
- Linux Network Isolation:
Block outgoing traffic (emergency containment) iptables -A OUTPUT -j DROP
- Windows Firewall Lockdown:
Disable all inbound/outbound rules netsh advfirewall set allprofiles state on netsh advfirewall firewall set rule name="all" new enable=no
3. Restore from Backups
- Linux (Tar Backup):
Extract and overwrite corrupted files tar -xzvf /backup/critical_data.tar.gz -C /
- Windows (WBAdmin):
Restore system state from backup wbadmin start recovery -version:MM/DD/YYYY -itemtype:file -items:C:\Data
4. Post-Recovery Validation
- Check for Residual Malware (Linux):
Scan for suspicious processes ps aux | grep -E "crypt|ransom|malware"
- Windows Event Log Analysis:
Filter ransomware-related events Get-WinEvent -LogName Security | Where-Object {$<em>.ID -eq 4688 -and $</em>.Message -like "malicious"}

What Undercode Say:
Ransomware recovery isn’t just about tools—it’s about muscle memory. Practice these commands regularly:
– Linux:
Monitor real-time file changes (detect encryption) inotifywait -m -r /critical/path -e modify,create,delete
– Windows:
Enable controlled folder access (anti-ransomware) Set-MpPreference -EnableControlledFolderAccess Enabled
Automate backups, test restores, and simulate attacks. The workshop’s live drill will reinforce these tactics.
Prediction:
Ransomware will increasingly target hybrid cloud environments. Organizations that integrate automated backup checks and zero-trust policies will recover fastest.
Expected Output:
A hardened recovery plan with executable commands, reducing downtime from days to hours.
