Protecting Your Server from Ransomware
Ransomware encrypts your files and demands ransom. Backup + updates + firewall + training = effective protection. We explain the steps.
What Is Ransomware?
Ransomware is malicious software that encrypts your files and demands payment in exchange for the decryption key. In 2024, the average ransom demand exceeded $1.5 million. 80% of victims who paid experienced a second attack.
Regional numbers: The Middle East saw a 77% increase in ransomware attacks during 2024. Saudi Arabia is among the most targeted countries in the region due to its strong economy.
How Does Ransomware Spread?
1. Email (Phishing)
65% of ransomware attacks begin with an email containing a malicious link or attachment. A message that appears to come from a trusted source — an invoice, urgent request, shipping notification.
2. System Vulnerabilities
Unpatched systems = open door. Vulnerabilities like EternalBlue (exploited in WannaCry) infected 200,000+ devices in a single day.
3. Remote Desktop Protocol (RDP)
RDP exposed to the internet without protection = easy target. Attackers use brute-force tools to guess passwords.
4. Pirated Software
Cracked software often contains hidden ransomware. The math is simple: free software = your data is the price.
5. Supply Chain
Compromising a single service provider reaches all their clients. The Kaseya incident in 2021 affected 1,500+ companies through one provider.
Complete Protection Strategy
Layer 1: Prevent Infection
Immediate Updates:
- Enable automatic updates on all systems
- Critical security patches: within 24 hours of release
- Regular updates: within one week
Email Security:
- Advanced spam filter
- Block executable attachments (.exe, .bat, .ps1)
- Train employees to recognize phishing
RDP Security:
- Never expose RDP directly to the internet — ever
- Use VPN for remote access
- Enable Network Level Authentication
- Limit failed login attempts
Limited Privileges:
- Least privilege principle for every user
- Never use admin accounts for daily work
- Review permissions every 3 months
Layer 2: Early Detection
| Tool | Function |
|---|---|
| EDR (Endpoint Detection) | Monitor file and process behavior |
| SIEM | Aggregate and analyze event logs |
| IDS/IPS | Detect and prevent intrusion |
| Network monitoring | Discover abnormal traffic |
Early Infection Indicators:
- Files with unusual extensions (.encrypted, .locked, .crypted)
- Sudden system slowdown (encryption consumes resources)
- Unknown processes consuming high CPU
- External connections to suspicious addresses
Layer 3: Backup (The Last Line of Defense)
The 3-2-1-1 Rule:
- 3 copies of your data
- 2 different storage media
- 1 copy offsite
- 1 copy offline (air-gapped)
The offline copy is the most critical. Modern ransomware actively searches for connected backups and encrypts them too.
Restore Testing:
- Test backup restoration monthly
- A backup without restoration testing = worthless
- Document your actual Recovery Time Objective (RTO)
What to Do If You Get Hit
- Do not pay the ransom — 80% experience a second attack after paying
- Isolate affected systems from the network immediately
- Do not power off devices — you may lose critical evidence in memory
- Notify your response team and begin executing the plan
- Identify the ransomware variant — some have free decryption tools (nomoreransom.org)
- Restore from backup after confirming it is clean
- Report to authorities (NCA in Saudi Arabia)
Secure Infrastructure First
CLOUD (cloud.net.sa) servers provide daily backups with 7 or 30-day retention options. Built-in DDoS protection at affordable pricing. Full account isolation. Infrastructure designed to minimize the attack surface from day one.
