The ransom message is written in Russian and states the following:

The note of the WannaCash ransomware virus states that your files are encrypted. You are demanded to pay 4999 Russian Rubles (near 80 US dollars) and transfer the sum via Yandex Money to allegedly restore your files as seen below:

However, 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.

WannaCash Ransomware – Encryption Process

What is known for the encryption process of the WannaCash ransomware is that every file that gets encrypted will become simply unusable. All encrypted files will receive the “encrypted” prefix appended to them. Filenames and their original extensions will be preserved but enclosed with round brackets and the “encrypted” word put before the brackets.

If the ransom note is correct, the following extensions will be targeted for the encryption process:

→.doc , .docx , .xls , .xlsx , .xlst , .ppt , .pptx , .rtf , .pub , .pps , .ppsm , .pot , .pages , .indd , .odt , .ods , .pdf , .zip , .rar , .7z , .jpg , .png , .mp4 , .mov , .avi , .mpeg, .flv , .psd , .psb

However, if the list becomes more complete, the article will get duly updated with the new additions.

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 WannaCash 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. That is due to the fact that the command eliminates one of the prominent ways to restore your data. If a computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore some files back to their normal state.
