Moss was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the encryption is successfully accomplished, the users are unable to get access to them. Moss virus includes its own “.moss” to all the encrypted files. For instance, the file “price_list.xls”, as soon as crypted by Moss, will be titled as “price_list.xls.moss”. Once the encryption is achieved, Moss puts its own distinct text file (_readme.txt) into all the folders that save the encrypted files.
The message specified by text file asking for the random os extremely comparable to the alerts given by other ransomware dangers coming from the DJVU family. The warning essentially indicates that the data has been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this statement is definitely real.
The approach to secure the files utilized by Moss is not totally looked into. Nevertheless, there is no doubt that each computer owner may be released an unique decryption key, which is definitely special. It is extremely difficult to recover the data without the proper key in location.

One more peculiarity of the Moss virus is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the total control by the scoundrels who have actually released the Moss ransomware into the web.
