How to Prepare for a Ransomware Attack – Virtual Ransomware Fire Drill Workshop

Ransomware attacks are escalating, and organizations must be prepared to respond swiftly. The Virtual Ransomware Fire Drill Workshop on June 11, 2025, offers hands-on simulations to strengthen recovery strategies.

You Should Know:

1. Detection & Isolation

Use these commands to detect suspicious activity and isolate infected systems:

Linux:

 Monitor network connections 
netstat -tulnp

Check for unusual processes 
ps aux | grep -E '(crypt|ransom|malware)'

Isolate a compromised machine from the network 
sudo iptables -A INPUT -s <infected_IP> -j DROP 

Windows:

 List active connections 
netstat -ano

Terminate malicious processes 
taskkill /F /PID <suspicious_PID>

Block inbound/outbound traffic to attacker C2 
netsh advfirewall firewall add rule name="Block_Ransomware" dir=out action=block remoteip=<malicious_IP> 

2. Backup Verification

Ensure backups are intact and untampered:

 Check backup integrity (Linux) 
sha256sum /backups/.tar.gz

Compare with known good hashes 
grep -vf known_hashes.txt backup_hashes.txt 

3. Incident Response Playbook

Execute a predefined response plan:

 Lock down critical files (Linux) 
sudo chattr +i /etc/passwd /etc/shadow

Disable SMB (Windows) 
Stop-Service -Name LanmanServer -Force 

4. Post-Attack Forensics

Collect logs for analysis:

 Export Linux auth logs 
grep -i "fail|invalid" /var/log/auth.log > auth_analysis.txt

Dump Windows Event Logs 
wevtutil qe Security /f:text /rd:true > security_logs.txt 

What Undercode Say:

Ransomware resilience requires proactive measures—regular backups, network segmentation, and employee training. The workshop’s live simulation will refine real-world response tactics.

Prediction:

Ransomware will increasingly target cloud backups, necessitating air-gapped and immutable storage solutions. AI-driven anomaly detection will become critical in early threat identification.

Expected Output:

• Detection logs (auth_analysis.txt, security_logs.txt)
• Blocked IPs (via iptables/netsh)
• Verified backup hashes (sha256sum)
