Ransomware is one of the most devastating cyberthreats. In 2026, thousands of businesses, hospitals and individuals fall victim every day. Here's how to understand and avoid this threat.

What is ransomware?

Ransomware is malicious software that encrypts your files and demands a ransom to decrypt them. Without the decryption key, your data is inaccessible.

How does it spread?

  • Phishing emails: Malicious attachments or booby-trapped links
  • Compromised websites: Automatic downloads without your consent
  • Unpatched vulnerabilities: Outdated systems exploited by attackers
  • Exposed RDP: Poorly secured remote desktop protocols
⚠️ NEVER pay the ransom. Paying doesn't guarantee data recovery and encourages attackers to continue. Only 65% of victims who pay actually get their files back.

How to protect yourself?

  • Regular backups: Apply the 3-2-1 rule with at least one offline copy
  • Updates: Keep all your software up to date
  • Antivirus: Use an up-to-date antivirus with real-time protection
  • Training: Learn to recognize phishing emails

What if you're a victim?

1. Immediately disconnect the device from the network. 2. Don't pay the ransom. 3. Contact authorities (CISA in the USA). 4. Restore from backups. 5. Analyze how the attack occurred to prevent recurrence.
