Hhmm Virus Removal Guide (+Decrypt .hhmm files)

Hhmm Virus – Details

Hhmm is a destructive software application working as typical ransomware. Michael Gillespie, the well-known virus researcher, first found this new name in the DJVU ransomware family.

Hhmm was created for the sole function to encrypt all popular file types. Logically, as soon as the encryption is effectively accomplished, the users are unable to get access to them. Hhmm virus adds its own “.hhmm” to all the encrypted files. For instance, the file “price_list.xls”, as soon as crypted by Hhmm, will be entitled as “price_list.xls.hhmm”. When the encryption is achieved, Hhmm puts its own distinct text document (_readme.txt) into all the folders that save the encrypted files.

The message stated by _readme.txt requesting the random os very similar to the notifications provided by other ransomware dangers belonging to the DJVU family. The warning basically indicates that the data has been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.

The technique to secure the files used by Hhmm is not entirely investigated. However, there is no doubt that each computer system owner may be issued an unique decryption key, which is absolutely special. It is incredibly hard to recuperate the data without the appropriate type in location.

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

One more peculiarity of the Hhmm 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 released the Hhmm virus into the internet. In order to obtain the key and restore the crucial data, the users are informed to connect with the scams via e-mail or by telegram and to pay the ransom in the quantity of $980.

The message also states that the people must contact the Hhmm authors within 72 hours upon the moment of the information encryption. The alert suggests that by doing so the people will get a 50% discount rate, for that reason, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we highly recommend that you do not pay the ransom. There is no warranty that these online criminals will keep their guarantees, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. For this reason, paying ransom typically does not lead to an effective healing. So, the users might just lose their money for nothing.

Likewise, we urge you not to contact the scams as they advise. Do not transfer money into their wallets. There are no applications that could crack the Hhmm virus or restore the data at no charge. Therefore, the only right choice is to bring back the data from possible backups (if offered).
