For evidence that the key truly exists, cybercriminals offer to send them one file for free unlocking. Additionally, two email addresses or are added as a way to show contact and discuss all matters.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Cube from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

Spotting .cube files shouts out about the Cube ransomware infection that has somehow managed to infiltrate your computer system. Continue with the following techniques to restore some of your files back to their previous positions.

If your files are encrypted by Cube, you can use several methods to restore them:

Data Recovery Pro is file unlocking software:

By using this tool you slightly increase your chances of unlocking files and documents that have been encrypted or corrupted in other ways.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Cube ransomware;
  • Restore them.

Windows Previous Versions can be used for file restoring purposes:

If the System Restore mode has already been enabled on your computer, you can continue to unlock your files by performing all steps necessary.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Use Shadow Explorer to unlock encrypted data:

This third-party software is created for data recovery purposes of these files which did not have their Shadow Volume Copies deleted or damaged.

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

There has been no official decryption tool for Cube ransomware released recently.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Cube and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
