Is VirtualBox Safe or Is It a Security Risk?

VirtualBox is a popular open-source virtualization program used by individuals and enterprises. If you have tried creating virtual machines on your Windows or Linux system, you may have already used it.

Considering it can be used for so many purposes, and by a wide range of people, you need to ask yourself: is it entirely safe for use? What are some of the risks that you should be aware of? Let us highlight a few details regarding the security of VirtualBox.

Is VirtualBox for Linux and Windows Safe to Use?

Yes, VirtualBox is safe to use on any supported platform. It was developed by Oracle, one of the biggest software companies. It is not a security threat to your computer out of the box.

However, when you use it to create a Virtual Machine (VM) for a specific purpose, you must take care of a few things.

When Is VirtualBox a Potential Security Risk?

Technically, VirtualBox isolates the VM from your host operating system. But some user actions may risk exposure to malware from the virtual machine to the host. (For clarity, the host refers to the system you use to install the VirtualBox program.)

Here are some cases when VirtualBox may help malicious actors to infect your computer system.

1. You Don’t Update the Virtual Machine

No matter whether it’s a Windows virtual machine or any other operating system, the VM should be regularly updated to ensure proper security.

Of course, there are use cases when you may not want to update it; for instance, testing a specific version of the operating system as a VM. In that case, you should immediately delete the VM after testing or update it as soon as possible.

2. File Sharing Is Enabled Between Host and VM

If you decide to share your files or folder with the virtual machine, it opens up a potential spot for malware to get into your computer.

This is highly likely because users do not usually install antivirus programs on virtual machines. So, when you download a file from an unknown source from within the VM, it may not be safe to use.

3. Using a Vulnerable Application

Virtual Machines are meant for testing. So, users try a wide range of applications they would rather not install on their host system. Some of those applications could have security risks that may allow malware to slip into your host operating system if you have file sharing enabled.

4. Using an Outdated VirtualBox Version

VirtualBox, like any program, can have bugs that pose a security risk. So, if you are using a particular version of VirtualBox and have not upgraded it, you should consider updating it immediately.

Is VirtualBox a Security Risk?

No, not really. There are millions of VirtualBox users running virtual machines without any major hiccups.

However, if you would rather not take any chances, the tips mentioned above should afford you an even safer VirtualBox experience.
