Vvyu was created for the sole function to encrypt all popular file types. Realistically, as soon as the encryption is effectively achieved, the users are unable to get access to them. Vvyu virus adds its own “.vvyu” to all the encrypted files. For example, the file “price_list.xls”, as soon as modified by Vvyu, will be titled as “price_list.xls.vvyu”. As soon as the file encryption is achieved, Vvyu puts its own distinct text file (_readme.txt) into all the folders that store the encrypted files.
The alert mentioned by document requesting the random os very comparable to the notices given by other ransomware threats coming from the DJVU family. The caution basically shows that the information has been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely real.
The method to encrypt the files utilized by Vvyu is not totally researched. Nevertheless, there is no doubt that each computer system owner might be issued a special decryption key, which is definitely special. It is extremely difficult to recuperate the information without the appropriate key in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Vvyu virus is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the crooks who have actually released the Vvyu ransomware into the internet. In order to get the key and bring back the essential data, the users are told to get in touch with the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.
The message also states that the people need to contact the Vvyu authors within 72 hours upon the minute of the data file encryption. The alert shows that by doing so individuals will get a 50% discount, therefore, the ransom amount falls to $490.
