The Small Business Ransomware Survival Guide (2025 Edition)

Introduction: Why This Guide Matters

Ransomware is one of the most damaging threats facing Canadian small businesses today—and it’s only getting worse.

In 2025, attacks will be smarter, faster, and more expensive than ever. But the good news? You don’t need to be a cybersecurity expert to prepare.

This guide is your go-to playbook for understanding ransomware, preventing it, and responding quickly if your business is ever hit. Let’s break it down.

1. How Ransomware Gets In

Understanding how ransomware gets in is the first step to keeping it out. Here are the most common entry points:

• Phishing Emails – Fake emails trick staff into clicking dangerous links or attachments.

• Malicious Ads or Websites – Clicking the wrong ad or visiting an infected site can trigger an automatic download.

• Infected USB Drives – One plug-in can spread ransomware across your network. ( If it was a USB I didn’t buy, it might be a USB that makes me cry )

• Outdated Software – Old apps or operating systems are open doors for hackers.

• Weak Remote Access – Using Remote Desktop (RDP) without strong passwords or MFA is risky.

• Free “Utility” Tools – Some free file converters or downloaders contain hidden malware.

2. Signs Ransomware has hit you

Here’s how to spot it early:

• Files are renamed or encrypted and no longer open.

• A ransom note pops up demanding payment in crypto.

• Your computer is suddenly very slow or acting oddly.

• Antivirus tools are disabled or throwing up red flags.

• You’re locked out of key apps or files.

If something feels off, trust your gut and unplug the device.

3. Preparation: What to Do Before It Happens

A little prep goes a long way. These steps can reduce damage and downtime:

✅ Back up your data – Automatically and regularly. Keep at least one backup offline.
✅ Update your software – Enable auto-updates for your OS, browser, and core tools.
✅ Train your team – Phishing awareness is the best frontline defence.
✅ Use Multi-Factor Authentication (MFA) – Highly recommended for all accounts but especially for email, finance, and admin logins.
✅ Test your backup recovery process – Practice restoring data before it’s urgent.
✅ Look into ransomware recovery services – Vet providers now, not during a crisis.
✅ Consider cyber insurance – Many Canadian providers offer affordable small business coverage.

4. What NOT to Do During a Ransomware Attack

When panic sets in, mistakes happen. Here’s what to avoid:

❌ Don’t reboot infected systems without advice—this could spread the attack.
❌ Don’t reconnect your backups immediately—they might get infected too.
❌ Don’t pay the ransom before consulting experts—you may never get your files back.
❌ Don’t go public on social media immediately—control the message and notify affected parties directly.

5. Ransomware Playbook: What to Do If You’re Attacked

STEP 1: Disconnect Everything

• Turn off Wi-Fi.

• Unplug affected devices.

• Remove network cables.

STEP 2: Call for Help

• Notify your IT team or provider.

• No IT support? Take screenshots, document error messages, and preserve evidence.

STEP 3: Report the Incident

• Canadian Anti-Fraud Centre: 1-888-495-8501

• Cyber Centre (Canada): [email protected]

• Your cyber insurance provider, if you have one

STEP 4: Don’t Pay the Ransom

• There are no guarantees you’ll get your data back.

• You may be marked as an easy repeat target.

STEP 5: Restore from Backup

• Only once your system is cleaned and verified safe.

• Use offline or cloud backups that haven’t been connected since the infection.

STEP 6: Change All Passwords

• Especially for email, finance, payroll, and admin accounts.

• Roll out MFA to protect accounts moving forward.

STEP 7: Communicate Internally (and Carefully)

• Let your staff know what’s going on and what to avoid.

• If customer data is affected, follow privacy regulations and notify appropriately.

6. After the Attack: Learn, Improve, and Move Forward

Once the smoke clears, do a post-incident review:

• How did the attack happen?

• What systems were affected?

• What worked—and what needs to change?

Then:

✅ Update your defences – Patch vulnerabilities and update security tools.
✅ Review access permissions – Remove access that’s no longer needed.
✅ Boost employee training – Make phishing awareness a regular thing.
✅ Refine your recovery plan – Keep it simple, tested, and up to date.

If possible, work with a recovery partner to create a long-term resilience plan.
