Hhjk was created for the sole purpose to encrypt all popular file types. Logically, as quickly as the encryption is effectively accomplished, the users are unable to get access to them. Hhjk virus adds its own “.hhjk” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Hhjk, will be titled as “price_list.xls.hhjk”. Once the file encryption is accomplished, Hhjk puts its own unique text file (_readme.txt) into all the folders that save the encrypted files.
The message mentioned by document requesting the random os extremely comparable to the notices provided by other ransomware hazards coming from the DJVU family. The warning basically shows that the information has been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is absolutely true.
The technique to encrypt the files utilized by Hhjk is not completely looked into. Nevertheless, there is no doubt that each computer system owner may be released a special decryption key, which is definitely unique. It is extremely difficult to recuperate the information without the suitable key in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Hhjk infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have actually launched the Hhjk ransomware into the internet. In order to obtain the key and restore the essential data, the users are informed to contact the scams by means of e-mail or by telegram and to pay the ransom in the amount of $980.
The message also states that the people must get in touch with the Hhjk authors within 72 hours upon the moment of the data encryption. The alert shows that by doing so the people will acquire a 50% discount rate, therefore, the ransom amount drops down to $490.
