What Is Ransomware and How To Protect Your Practice From An Attack

Written by Amy Carbone | Jul 11, 2025 2:28:53 PM

For business owners, particularly those in dentistry where there are strict and specialized requirements, data protection is a topic that cannot be overemphasized. Protecting patient information goes far beyond paper-based forms to safeguarding all forms of electronic data.

What happens if a cybercriminal gains access to that data, secures it, and refuses to release it back to you? Here's some of what you should know.

 

What Is Ransomware?

Ransomware is a kind of malware, or malicious software, that is designed to hold a computer or data "hostage" until the "ransom" is paid. What this often looks like is being denied access to your system or specific data until the hacker removes the malware. Often, systems are not restored or data returned even if the cyberattacker pays the "ransom."

Traditionally, visiting suspicious websites or phishing emails were the primary ways ransomware might infect a system. Today, those “old-school” tactics are still used, but now ransomware is also commonly delivered via remote desktop protocol (RDP) (think screen software) vulnerabilities, third-party software exploits, and compromised managed service providers (MSPs).

 

Why Is Ransomware a Threat to Dental Practices?

Ransomware is truly a threat to any company using the internet to do business. However, medical and dental practices that keep patient insurance and payment information on file could be at a higher risk for ransomware attacks than other types of businesses: 

  • Smaller healthcare providers are often targeted for two reasons. First, hackers assume that dental practice cybersecurity measures are weaker, typically relying on local practice management software with unsophisticated data protection. 
  • Perhaps more importantly, dental practices have valuable patient data that is lucrative on the dark web.

The costs of falling victim to ransomware can’t be overstated. From the actual costs of restoring lost data to lost reputation, a practice owner can become completely immobilized. And if the attack is handled improperly or covered up, fines can be substantial. 

 

Ransomware Protection: 5 Dental Practice Cybersecurity Practices

Here’s how dentists and practice managers can help protect against the threat of ransomware:

1. Configure Practice Firewalls

Your firewall serves as the front line between your practice and the internet — it’s critical that it’s properly configured to block unauthorized access, detect suspicious activity, and filter out threats in real time. 

2. Implement Real-Time Encrypted Backups

If your office faces a dental office ransomware attack, it can be difficult to get your data back. For your practice to recover quickly after a ransomware attack, you need to be able to restore patient records and other critical data as quickly as possible. If you make copies of your data, you'll revert to the last copy, but if it was captured three months ago, data from patient appointments over the last several weeks will likely be lost.

Instead, you should implement real-time or hourly encrypted backups, ideally using cloud-based, off-site solutions. Many modern backup services now offer immutable backups (data that can't be altered or deleted), which further protects against ransomware encryption.

3. Conduct Regular Employee Cybersecurity Training

Most ransomware attacks begin with phishing emails or websites, making it essential to train your team on how to recognize and respond to online threats. 

All employees, regardless of their position in your practice, should understand how to safely browse the internet, identify suspicious attachments or links, and avoid falling for impersonation scams. Ask your IT company to help you host a working lunch or training seminar to educate your staff on how to identify and mitigate risks, and ensure you provide regular, updated training. 

4. Keep All Practice Software Updated

Often, outdated systems and computer applications are the targets of ransomware attacks, making it critical to keep all software as current as possible with updated cybersecurity protection.. 

If you have an on-premise dental practice management solution, can it be moved to a secure, cloud-based system with your IT provider, or is it time to switch to a more current cloud-based solution that updates automatically with built-in ransomware protections? 

5. Install Advanced Threat Protection Tools

Gone are the days when simple spam filters were enough to protect from ransomware threats. 

Instead, you now need real-time URL scanning, attachment sandboxing, and AI-powered detection. Opt for best-in-class solutions, such as Microsoft Defender for Office 365 or Google Workspace, which offer enhanced threat protection and more comprehensive safeguards.

 

Unprepared for a Ransomware Attack? The Fallout Could Cost You Your Practice

According to recent industry data, the average general dental practice in the U.S. now generates just over $1 million. How much of that income are you willing to lose to cybercrime?

When it comes to the risk of ransomware, all it takes is reading the news to know that you can’t eliminate the risk of a hacker holding your data ransom. 

Fortunately, there is another way to safeguard your income — with data breach protection. This coverage is one type of insurance that savvy practice owners carry to mitigate business risks.
