Yyto ransomware might deliver its infection via different ways. The payload file which executes the malicious script for this ransomware, that in turn infects your computer machine, is circling around the Internet. Samples of this ransomware have been found by a few different malware researchers.

.Yyto Files Virus – A Closer Look

The Yyto ransomware is a cryptovirus, which has been recently discovered by malware researchers. When the Yyto ransomware encrypts your files, it will put the .Yyto extension to every one of them and then display a ransom note with payment instructions.

The Yyto ransomware can be set to make new registry entries in the Windows Registry to achieve a higher level of persistence. Such entries are usually designed in a way that will start the virus automatically with every launch of the Windows Operating System, such as the example shown here:


The ransom message is placed inside a file called how_to_decrypt.txt. This is how it looks:

The ransom note states the following:

If you don’t have a email in TOR network:

1) Download and install the browser for the TOR network: https://www.torproject.org/download/download-easy.html
2) Launch browser and go to the link (create email in TOR network): torbox3uiot6wchz.onion
3) Write on email: cutterswish@torbox3uiot6wchz.onion
4) Wait for a response.


Your personal key:

The cybercriminals want you to write to the cutterswish@torbox3uiot6wchz.onion e-mail address by only using a TOR e-mail yourself. Here is how the TorBox service which they suggest you register on, looks like:

You should NOT under any circumstances pay or write to these crooks. Nobody can give you a guarantee that you will get your files decrypted upon payment, plus in that way you will support the criminals and probably motivate them to keep making ransomware viruses.

.Yyto Files Virus – Encryption Process

There is no official list with file extensions that the Yyto ransomware seeks to encrypt and the article will be updated if such a list is discovered. However, all files which get encrypted will receive the .read_to_txt_file.yyto extension appended to them. The encryption algorithm which is used for the virus is currently unknown.

The ransomware could encrypt files, which are from the following file types:

  • Audio
  • Video
  • Database
  • Document
  • Picture

The Yyto cryptovirus might be set to erase the Shadow Volume Copies from the Windows Operating System by executing the following command:

→vssadmin.exe delete shadows /all /Quiet

The execution of the above-stated command, makes the encryption process more viable, as one of the main ways for file recovery is gone. Continue to read and find out what methods you can try out to potentially restore some of your data.
