Prevention Layers

1

Backups (Most Important)

Follow the 3-2-1 rule: 3 copies, 2 storage types, 1 offsite. If ransomware hits, you restore from backup and lose nothing. Keep at least one backup disconnected from your network.

2

Software Updates

Most ransomware exploits known vulnerabilities that have patches available. Enable automatic updates for OS, browser, and all applications.

3

Email Caution

70% of ransomware arrives via email. Don't open unexpected attachments. Verify links before clicking. Report suspicious emails. See our phishing guide.

4

Endpoint Protection

Use Windows Defender (built-in, adequate for most users) or a reputable third-party solution. Enable ransomware protection features like Controlled Folder Access (Windows).

5

VPN + Threat Protection

A VPN prevents network-level attacks on public Wi-Fi. VPN providers like NordVPN include Threat Protection that blocks known malicious domains.

6

Principle of Least Privilege

Don't use an admin account for daily work. Create a standard user account. This limits ransomware's ability to encrypt system files and spread.

If You're Hit: Emergency Steps

  1. 1. Disconnect immediately — Unplug ethernet, disable Wi-Fi. Prevent spread to other devices and network drives.
  2. 2. Do NOT pay the ransom — Payment doesn't guarantee recovery and funds criminal operations.
  3. 3. Document everything — Take photos of ransom screens, note the variant name if shown.
  4. 4. Report — To your company IT, local law enforcement, and FBI IC3 (ic3.gov) or equivalent.
  5. 5. Check No More Ransom — nomoreransom.org may have a free decryption tool for your variant.
  6. 6. Restore from backup — Wipe the infected device and restore from a clean backup.
  7. 7. Change all passwords — From a clean device, change passwords for all accounts.

Frequently asked

Frequently Asked Questions

A VPN alone cannot prevent ransomware, but it helps. VPN encrypts your traffic (preventing some delivery methods on public Wi-Fi) and some VPNs include threat protection that blocks known malicious domains. But ransomware primarily spreads through phishing emails and malicious downloads — you need a multi-layered defense.
Law enforcement agencies universally recommend NOT paying. Payment funds criminal organizations, doesn't guarantee you'll get your data back, and marks you as a target for future attacks. Instead, restore from backups and report to authorities.
Common vectors: (1) Phishing emails with malicious attachments or links, (2) Compromised websites (drive-by downloads), (3) Exploiting unpatched software vulnerabilities, (4) Malicious USB devices, (5) Compromised remote desktop (RDP) connections.
Yes, though less common than Windows. Mac ransomware exists (KeRanger, ThiefQuest). Mobile ransomware typically locks the screen rather than encrypting files. All platforms benefit from the same prevention measures: backups, updates, and caution with downloads.
