No system is safe

Even if a note is shown, you should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that. Adding to that, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal activities. That may even result to you getting your files encrypted all over again after payment.

.RYK Files Virus (Ryuk) – Encryption Process

A list with the known, targeted extensions of files which are sought to get encrypted is currently very small. Files which get encrypted have the following extensions:

→ .doc, .docx, .jpg, .jpeg, .xls, .xlsx, .pdf

The files used most by users and which are probably encrypted are from the following categories:

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

The .RYK Files cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the above-stated command is executed that will make the effects of the encryption process more efficient.
