How to Defend Against Ransomware Attacks

Ransomware is no longer a distant threat—it’s a pressing reality. Organizations must be prepared to respond swiftly and effectively. Below are critical steps to mitigate ransomware risks and recover from attacks.

You Should Know:

1. Prevention Measures

• Patch Management: Keep systems updated to close vulnerabilities.

  sudo apt update && sudo apt upgrade -y  Linux 
  

• Disable RDP if Unused: Reduce attack surfaces.

  Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\Terminal Server" -Name "fDenyTSConnections" -Value 1  Windows 
  

• Use Strong Passwords & MFA: Enforce multi-factor authentication.

2. Detection & Monitoring

• Enable Audit Logs:

  sudo auditctl -a always,exit -F arch=b64 -S execve  Monitor executions 
  

• Deploy SIEM Tools: Use Wazuh or Splunk for real-time alerts.

3. Incident Response Plan

• Isolate Infected Systems:

  sudo ifconfig eth0 down  Disable network interface 
  

• Identify Ransomware Strain: Use ID Ransomware (https://id-ransomware.malwarehunterteam.com/).

4. Recovery Tactics

• Restore from Backups: Ensure backups are offline (air-gapped).

  tar -xvzf backup.tar.gz -C /restore/path  Extract backup 
  

• Use Decryption Tools (if available):
• No More Ransom Project: https://www.nomoreransom.org/

5. Post-Attack Hardening

• Conduct a Security Audit:

  lynis audit system  Linux security scanning 
  

• Train Employees: Phishing simulations and cybersecurity awareness.

What Undercode Say

Ransomware attacks are evolving, but proactive defense minimizes damage. Regular backups, endpoint protection, and employee training are critical. Organizations must simulate attacks (like Druva’s Ransomware Fire Drill) to test readiness.

Expected Output:

• Secure backups (verified recovery process).
• Disabled unnecessary services (RDP, SMBv1).
• Active monitoring (SIEM + EDR solutions).

Prediction

Ransomware will increasingly target cloud storage and supply chains—zero-trust architecture will become essential.
