Jyos was developed for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is successfully achieved, the users are unable to get access to them. Jyos virus adds its own “.jyos” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Jyos, will be titled as “price_list.xls.jyos”. As soon as the file encryption is achieved, Jyos puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.
The alert mentioned by _readme.txt asking for the random os extremely comparable to the alerts given by other ransomware dangers coming from the DJVU family. The warning basically indicates that the files have been encrypted and the only solution to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.
The approach to secure the files used by Jyos is not totally looked into. However, there is no doubt that each computer system owner may be issued a special decryption key, which is definitely special. It is extremely difficult to recuperate the information without the suitable type in place.
One more peculiarity of the Jyos 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 introduced the Jyos infection into the internet. In order to obtain the key and bring back the crucial data, the users are informed to contact the scams through e-mail or by telegram and to pay the ransom in the amount of $980.
The message likewise states that the people should get in touch with the Jyos authors within 72 hours upon the minute of the information encryption. The alert shows that by doing so individuals will acquire a 50% discount rate, for that reason, the ransom quantity drops down to $490.
