Many voices claim that there is no need to bother searching for an antivirus for QNAP since all malware infections can be traced back to the source or the client.

Moreover, a fairly large amount of users believe that a thorough scan of all files prior to uploading them on your NAS should be enough to keep your data safe and your equipment clean.

But is that really how it works? As you probably guessed by now, we don’t buy it. Just like we don’t buy the fact that Linux-based systems are 100%, end-to-end, virus-immune. And it’s not that we enjoy being rebels without a cause and challenging the status quo just for the sake of making waves.

How do I secure my QNAP NAS?

QNAP NAS has had its fair share of risky encounters with ransomware, DDoS attacks, brute force attacks, and even crypto-mining malware throughout the years. Of course, this is no more than a handful of examples as the full inventory is much thicker.

The sensitive nature of the data enclosed by these devices raises concerns, but you should be able to harden your equipment by following some basic security practices.

How do I protect my QNAP from malware?

Here’s how to enhance security when it comes to your QNAP NAS:

  • Always install the latest updates and make sure you upgrade your OS, firmware, and applications to the latest versions available (Unpatched devices are more susceptible to security breaches and exploits).
  • Sanitize your device regularly (This includes the Malware Remover app, the built-in QNAP antivirus, and most and foremost, a specialized antivirus for QNAP).
  • Adopt a sensible password policy (Don’t be shy to use specialized tools such as password managers to help you set strong passwords that can resist brute-force attacks. Also, make sure you change your credentials and never use the default admin profile and passwords).
  • Secure your connection (Since keeping a NAS offline defeats the purpose of owning one, your best bet is to secure your connection. Enable SSL communication if it’s not already in place, avoid using default system ports such as 8080 and 443, secure your home router and use a good VPN tool to hide your IP and encrypt your traffic).
  • Eliminate superfluous elements and remove suspicious items (Don’t click on any suspicious links and remove all unknown accounts. Moreover, disable functionalities that you don’t actually use such as SSH, Telnet, or other web apps).

Is QNAP NAS secure?

QNAP devices run on a Linux-based OS, which is seen as one of the most secure and reliable systems out there. You’d think that it’s enough to keep threats at bay, right? Not quite.

A NAS serves as a Cloud backup solution for numerous apps and platforms and the assets requiring secure storage are usually sensitive, confidential, or otherwise important to the users that are struggling to protect them.

The very nature of the data held by QNAP devices is what makes them a particularly appealing target for hackers looking to steal information in exchange for profit.

And there is a clear record of both ransomware and malware attacks specifically targetting QNAP NAS devices.

The infamous AgeLocker ransomware went for obsolete and not upgraded QTS versions and preyed on Linux and macOS devices with a predilection for QNAP NAS customers.

Qlocker and eCh0raix are yet more examples of ransomware campaigns designed to exploit vulnerabilities in QNAP devices.

But there is more than just ransomware to dread. QNAP-specific malware also has a taste for causing havoc.

Take, for example, the QSnatch malware that shook the cybersecurity industry with its sophisticated hacking mechanisms coded so persistently that even admins were not able to deploy firmware updates.

Some are programmed to infect hardware while others aim to exfiltrate data including passwords, logs, and sys files in order to prey on unsecured SSH connections and ultimately get remote access.

Finally, QNAP NAS devices are high-profile targets for mining malware and there have been numerous attempts to exploit them in order to mine cryptocurrency. Does this ring a bell? If so, you couldn’t be more right.

Highly appreciated Raspberry Pi devices, which also run on a custom Linux-based system, were briefly compromised and used for cryptocurrency mining.

Needless to say at this point that securing your Raspberry Pi with a powerful antivirus solution is mandatory. So is safeguarding your QNAP NAS.

How to check if QNAP is infected?

How to tell if your QNAP NAS has been infected? While QNAP-targeted malware can be (even) trickier to spot, infestation signs will be there.

You just need to know where to look. Searching for processes with unusually high CPU usage is a good way to start troubleshooting.

Along with rapid battery drainage and overall system drowsiness, abnormal CPU consumption rates are the most common indicators of intrusion.

You can try to reboot your device to flush away malware. But this is not always a guaranteed fix, not to mention that a full factory reset will also flush away all your digital belongings.

Why take the chance when you can deploy the best antivirus for QNAP to stay one step ahead of hackers?
