It stores the "@Lütfen_Beni_Oku!@.txt" and "@Please_Read_Me@.txt" text files (ransom messages) in all folders that contain encrypted files.

It changes the wallpaper by using an image called "@Wallpaper@.png" and displays a pop-up window by launching the "@MMDecrypt0r@.exe" executable file. Both of these files can be found on the desktop. MMDecrypt is a new variant of KesLan ransomware and was discovered by GrujaRS.
