Hgfu Virus Removal Guide (+Decrypt .hgfu files)

Hgfu Virus – Details

Hgfu is a destructive software working as common ransomware. Michael Gillespie, the widely known malware researcher, very first found this new name in the DJVU ransomware family.

Hgfu was developed for the sole function to encrypt all popular file types. Rationally, as quickly as the encryption is effectively achieved, the users are unable to get access to them. Hgfu virus includes its own “.hgfu” to all the encrypted files. For example, the file “price_list.xls”, as soon as crypted by Hgfu, will be titled as “price_list.xls.hgfu”. When the file encryption is achieved, Hgfu puts its own unique text file (_readme.txt) into all the folders that save the encrypted files.

The message specified by document requesting the random os really similar to the notifications provided by other ransomware threats belonging to the DJVU family. The warning generally indicates that the information has been encrypted and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.

The approach to secure the files used by Hgfu is not totally looked into. Nevertheless, there is no doubt that each computer system owner might be released an unique decryption key, which is definitely distinct. It is incredibly tough to recover the data without the proper type in location.

“Don’t worry, you can return all your files!”, from _readme.txt message:

One more peculiarity of the Hgfu 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 criminals who have actually released the Hgfu ransomware into the web. In order to obtain the key and bring back the essential data, the users are informed to contact the scams via e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise states that the people should call the Hgfu authors within 72 hours upon the moment of the information file encryption. The alert indicates that by doing so individuals will obtain a 50% discount, therefore, the ransom amount falls to $490.

No matter what the amount of the ransom is, we strongly encourage that you do not pay the ransom. There is no assurance that these online crooks will keep their pledges, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom frequently does not result in a successful healing. So, the users may merely lose their money for absolutely nothing.

Similarly, we prompt you not to contact the scams as they instruct. Do not transfer money into their wallets. There are no applications that might split the Hgfu ransomware or bring back the data at no cost. Therefore, the only appropriate choice is to restore the data from possible backups (if readily available).
