Vn_os Ransomware
Vn_os is a type of malware that encrypts files and displays a pop-up window, and creates the "___RECOVER__FILES__.vn_os.txt" file (ransom notes). It renames encrypted files as well. Vn_os ransomware appends the ".vn_os" extension to their filenames. For example, it renames "1.jpg" to "1.jpg.vn_os"
