.SOLO Files Virus – Encryption Process

The primary goal of .SOLO ransomware is data encryption. During the

encoding process, the ransomware utilizes one of the most sophisticated cipher algorithms – AES. This cipher replaces the original code of target files with other specifically ordered characters. Following these changes, corrupted files remain inaccessible while their names are set to contain the extension .SOLO.

In order to make you more prone to pay the ransom, hackers usually configure their threats to corrupt all your:

  • Audio files
  • Video files
