Hhyu was created for the sole function to encrypt all popular file types. Logically, as quickly as the encryption is successfully achieved, the users are unable to get access to them. Hhyu virus adds its own “.hhyu” to all the encrypted data. For instance, the file “price_list.xls”, as soon as modified by Hhyu, will be entitled as “price_list.xls.hhyu”. When the file encryption is accomplished, Hhyu puts its own distinct text document (_readme.txt) into all the folders that keep the encrypted files.
The message stated by _readme.txt asking for the random os very comparable to the notifications provided by other ransomware threats coming from the DJVU family. The caution basically indicates that the information has been encrypted and the only service to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely true.
The method to encrypt the files utilized by Hhyu is not totally researched. Nevertheless, there is no doubt that each computer owner may be issued a special decryption key, which is definitely distinct. It is exceptionally tough to recover the information without the suitable key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Hhyu infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the crooks who have actually launched the Hhyu virus into the web. In order to acquire the key and bring back the essential data, the users are told to get in touch with the frauds by means of e-mail or by telegram and to pay the ransom in the quantity of $980.
