Your Personal CODE:
The note of the Nozelesn ransomware virus states that your files are encrypted. You are demanded to pay money to allegedly restore your files. The demanded payment sum is 0.1000 Bitcoins which equals around 659 US Dollars at the time of writing of this article. 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 once again.
As seen from the ransom note, a domain is left for contacting the cyber criminals, namely “lyasuvlsarvrlyxz.onion”. Visiting the domain on the TOR Network yields the following result:

As stated before – do not trust the cybercriminals and do not pay the ransom.

What is known for the encryption process of the Nozelesn ransomware is that every file that gets encrypted will become simply unusable. All encrypted files will receive the “.nozelesn” extension appended to them as a secondary extension, leaving the original one and filename unchanged.
A list with the targeted extensions of files which are sought to get encrypted is currently unknown. However, if it becomes known, it will be posted here as an update to the article.
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 Nozelesn 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
