Yyza was developed for the sole purpose to encrypt all popular file types. Rationally, as quickly as the encryption is successfully accomplished, the users are not able to get access to them. Yyza ransomware adds its own “.yyza” to all the encrypted files. For example, the file “price_list.xls”, as soon as crypted by Yyza, will be titled as “price_list.xls.yyza”. As soon as the encryption is achieved, Yyza puts its own special text file (_readme.txt) into all the folders that save the encrypted files.
The alert mentioned by _readme.txt asking for the random os really similar to the notifications given by other ransomware hazards coming from the DJVU family. The caution essentially shows that the data has been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is definitely real.
The method to secure the files utilized by Yyza is not totally investigated. Nevertheless, there is no doubt that each computer system owner might be released a special decryption key, which is definitely special. It is exceptionally tough to recover the information without the suitable type in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Yyza infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the total control by the scoundrels who have released the Yyza ransomware into the internet. In order to acquire the key and restore the important information, the users are told to connect with the frauds by means of e-mail or by telegram and to pay the ransom in the quantity of $980.
The message also says that individuals need to contact the Yyza authors within 72 hours upon the moment of the information encryption. The alert suggests that by doing so the people will get a 50% discount rate, for that reason, the ransom amount falls to $490.
