Hlas Virus Removal Guide (+Decrypt .hlas files)

Hlas Virus – Details

Hlas is a malicious software application functioning as common ransomware. Michael Gillespie, the widely known virus researcher, first discovered this new name in the DJVU ransomware family.

Hlas was developed for the sole purpose to encrypt all popular file types. Logically, as quickly as the file encryption is successfully accomplished, the users are not able to get access to them. Hlas ransomware adds its own “.hlas” to all the encrypted files. For example, the file “price_list.xls”, as soon as modified by Hlas, will be entitled as “price_list.xls.hlas”. As soon as the file encryption is achieved, Hlas puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.

The message specified by _readme.txt requesting for the random os really similar to the alerts offered by other ransomware hazards belonging to the DJVU family. The caution basically indicates that the files have been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.

The method to encrypt the files used by Hlas is not completely looked into. However, there is no doubt that each computer system owner might be issued a special decryption key, which is absolutely special. It is very difficult to recover the data without the appropriate key in location.

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

message from Hlas virus

One more peculiarity of the Hlas 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 criminals who have released the Hlas virus into the internet. In order to acquire the key and bring back the essential data, the users are informed to connect with the frauds by means of email or by telegram and to pay the ransom in the amount of $980.

The message also states that individuals ought to get in touch with the Hlas authors within 72 hours upon the moment of the data encryption. The alert shows 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 quantity of the ransom is, we strongly recommend that you do not pay the ransom. There is no warranty that these online crooks will keep their guarantees, so they may not care at all what the victims feel about the encryption, even when the amount of the ransom is gotten into their accounts. Hence, paying ransom often does not result in an effective recovery. So, the users might just lose their money for nothing.

Similarly, we advise you not to get in touch with the frauds as they instruct. Do not transfer money into their wallets. There are no applications that might split the Hlas ransomware or bring back the information at no cost. For that reason, the only right decision is to restore the data from possible backups (if readily available).
