How to Hack Ransomware Recovery: A Live Fire Drill Workshop

Ransomware attacks are escalating, and recovery speed is critical. The Virtual Ransomware Fire Drill Workshop on June 11, 2025, offers hands-on simulations to sharpen your response tactics. Here’s what you need to know:

You Should Know:

1. Pre-Workshop Prep (Linux/Windows Commands)

• Identify Critical Data:

  Linux: Find sensitive files (modify extensions as needed) 
  find / -type f ( -name ".db" -o -name ".sql" -o -name ".conf" ) -exec ls -la {} \;
  
  Windows: List shadow copies (for recovery points) 
  vssadmin list shadows 
  

• Isolate Infected Systems:

  Linux: Block suspicious IPs 
  sudo iptables -A INPUT -s <ATTACKER_IP> -j DROP
  
  Windows: Disable network interfaces 
  netsh interface set interface "Ethernet" admin=disable 
  

2. Live Simulation Steps

• Detect Encryption in Progress:

  Linux: Monitor file changes (inotify) 
  inotifywait -m -r /var/www/ -e modify,create,delete | grep -i ".encrypted"
  
  Windows: Check for ransom notes 
  dir /s /b C:.README.txt 
  

• Contain the Attack:

  Linux: Kill suspicious processes 
  ps aux | grep -i "crypt" | awk '{print $2}' | xargs kill -9
  
  Windows: Stop services linked to ransomware 
  sc stop "suspicious_service" 
  

3. Recovery Tactics

• Restore from Backups:

  Linux: Rsync from backup server 
  rsync -avz backup_user@backup_server:/path/to/backup /restore/location
  
  Windows: Use WBAdmin for system state restore 
  wbadmin start recovery -version:<BACKUP_DATE> -itemtype:file -items:C:\Data 
  

• Decrypt Files (If Possible):

  Use tools like RakhniDecryptor (Linux/Windows) 
  ./RakhniDecryptor --file=/infected/file.encrypted --output=/clean/file 
  

What Undercode Say

Ransomware resilience hinges on proactive drills and automated recovery scripts. Practice these commands regularly:
– Linux: Automate backup checks with cron:

/30     /usr/bin/rsync -avz /critical/data backup_server:/backups 

– Windows: Schedule shadow copies via Task Scheduler:

schtasks /create /tn "DailyShadowCopy" /tr "vssadmin create shadow /for=C:" /sc daily /st 23:00 

Prediction

By 2026, ransomware will increasingly target cloud backups and API endpoints. Workshops like Druva’s will shift focus to cross-platform recovery (AWS/Azure/Linux/Windows).

Expected Output:

• Workshop URL: Join the Ransomware Fire Drill (Replace with actual link)
• Decryption Tools: NoMoreRansom Project
• Backup Best Practices: NIST SP 800-184 Guide

Note: Replace placeholder URLs with actual links if available.
