How to remove Oonn Ransomware and decrypt .oonn files

What is Oonn Ransomware

Oonn ransomware is another version of the common Stop (DjVu) ransomware family. Similar to the previous versions, as well as to all ransomware in general, Oonn ransomware encrypts user data in Oonnous formats, including photos, videos, archives, multimedia, text documents, tables, databases and much more. Many users are simply not ready to lose this data, because many do not even have backups of photos taken on vacation and the like. By the way, the virus can delete shadow copies of files and system restore points in order to prevent the user from recovering data using standard utilities. In plus, it changes files’ extensions to .oonn. Looking ahead, we note that the main task of the user is to delete Oonn ransomware immediately, and only then carry out any manipulations with the files.

In just a few days, Oonn ransomware spread across the globe, destroying user systems in all corners of the world. Also, Oonn ransomware creates the _readme.txt text file containing information about encryption and ransom methods. This file appears in all folders containing the attacked data.
