Currently, the threat is lurking across the web in active attack campaigns. There are several spread channels that are likely to be used for the distribution of .cube’s activation file. Among these techniques are malspam, malvertising, freeware packages, and corrupted web pages.

Since the emails that are part of malspam campaigns aim to trick you into downloading the payload on your PC, they often pose as representatives of legitimate businesses and institutions.

So beware of every email you see in your inbox and always check the security level of the elements is presents.

When activated on your PC, the payload file of .cube files virus sets the beginning of the attack. At first, it could attempt to connect to a remote server in an attempt to transfer some gathered details and receive additional malicious files/commands as a response. With the help of these additional files, the ransomware becomes able to disrupt system security and perform a long sequence of malicious activities. As a result of some applied changes that affect the registry keys Run and RunOnce, .cube virus could start loading automatically on every next system start.

After all initial attack stages, the ransomware reaches the main one – data encryption. It realizes the encryption process with the help of the highly sophisticated encryption algorithm. Files it targets are likely to be:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

Following the encryption process, the ransomware leaves all corrupted files inaccessible. It marks them with the extension .cube . Since the encryption process prevents you from accessing corrupted files, threat actors attempt to extort a ransom fee. For the purpose they use the following ransom message (READ_ME.cube):
