🔒 What Is Ransomware?

Ransomware is a type of malicious software that locks you out of your files or entire system. Criminals then demand payment (usually in cryptocurrency) to unlock your data. Sometimes they also threaten to leak sensitive information online if you refuse.

For a business, this could mean losing access to customer records, invoices, or payroll data. For an individual, it could be losing family photos, school projects, or important financial documents.

🚨 How Does Ransomware Spread?

Hackers use several common tricks to deliver ransomware:

  • Phishing Emails: Messages that look official but contain infected links or attachments.

  • Compromised Websites/Ads: Clicking on a fake ad or unsafe site can silently download malware.

  • Outdated Software: Old apps or operating systems often have security holes attackers exploit.

  • Weak Remote Access: Unsecured VPNs or remote desktops make it easy for hackers to break in.

🏠 Why You Should Care (End Users)

Even if you’re not running a business, you’re still a target. Ransomware can lock your personal laptop, making you lose access to photos, tax files, or work-from-home documents.

🏢 Why SMEs Should Care (Small Businesses)

Many small businesses assume hackers only care about large corporations—but the opposite is often true. SMEs usually have fewer resources and weaker defenses, making them an easier target. For a small café, shop, or local service, even a few days of downtime can be financially devastating.

✅ How to Protect Yourself

Here are the most effective steps you can take today to reduce your risk:

  1. Back Up Your Files

    • Use secure cloud storage or an external hard drive.

    • Keep at least one backup disconnected from your main system.

  2. Keep Software Updated

    • Always install security updates for your operating system, apps, and antivirus.

  3. Enable Multi-Factor Authentication (MFA)

    • Add an extra layer of protection for logins to sensitive accounts.

  4. Be Cautious Online

    • Don’t click on suspicious links or open attachments from unknown senders.

    • Double-check URLs before entering login details.

  5. Use Security Tools

    • Antivirus and anti-malware programs can block many threats before they spread.

  6. Have a Response Plan

    • Know what to do if you’re attacked: disconnect the device, don’t pay the ransom, and contact IT/security support immediately.
