What is Ransomware?

Ransomware is a type of cyberattack that works by attackers infiltrating your organization's systems, encrypting your files, and demanding ransom in exchange for the decryption key. In 2024, the cost of global ransomware attacks to the corporate world exceeded $20 billion.

10 Critical Protection Steps

1. Regular and Tested Backups

3-2-1 backup rule: 3 copies of data, 2 different media, 1 off-site (cloud or physical remote location). Critical: Test your backups regularly.

2. Software and System Updates

60% of attackers exploit known vulnerabilities. Establish automatic update policies and a patch management process.

3. Endpoint Security (EDR/XDR)

Traditional antivirus software is not sufficient. EDR (Endpoint Detection & Response) solutions detect next-generation threats through behavioral analysis.

4. Network Segmentation

Don't keep all your systems on the same network. Isolate critical systems, production network, and office network from each other. This way, an attack cannot spread to the entire system.

5. Multi-Factor Authentication (MFA)

MFA must be mandatory for VPN, email, and critical applications. A stolen password alone will not be sufficient.

6. Employee Awareness Training

The most common entry point for ransomware is phishing emails. Conduct phishing simulations and training at least twice a year.

7. Email Security

Configure your SPF, DKIM, and DMARC records. Filter malicious attachments with advanced email security solutions.

8. Remote Access Security

Don't leave RDP port (3389) open to the internet. Remote access should only be provided through VPN and with MFA.

9. Incident Response Plan

Prepare an Incident Response Plan before an attack occurs. Determine who will do what, which systems will be isolated, and who will be contacted.

10. Conduct Penetration Testing

Test yourself before attackers find you. Periodic penetration tests reveal your vulnerabilities before experiencing a real attack.

What Should You Do If You Experience a Ransomware Attack?

1. Immediately isolate affected systems from the network
2. Notify authorities (BTK, prosecutor's office)
3. Don't pay the ransom — payment does not guarantee data recovery
4. Get support from cybersecurity experts
