Ghas Virus Removal Guide (+Decrypt .ghas files)

Ghas – Ransomware

Ghas is a malicious software working as typical ransomware. Michael Gillespie, the well-known virus researcher, very first discovered this new name in the DJVU ransomware family.

Ghas was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the encryption is effectively accomplished, the users are unable to get access to them. Ghas ransomware adds its own “.ghas” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Ghas, will be titled as “price_list.xls.ghas”. When the encryption is achieved, Ghas puts its own special text document (_readme.txt) into all the folders that keep the encrypted files.

The message mentioned by text file requesting the random os really comparable to the alerts given by other ransomware threats coming from the DJVU family. The warning essentially shows that the files have been encrypted and the only option to get access to it is to use an unique standalone key. Regretfully, this declaration is absolutely real.

The approach to secure the files utilized by Ghas is not entirely researched. Nevertheless, there is no doubt that each computer system owner may be issued an unique decryption key, which is absolutely special. It is very difficult to recover the data without the proper type in location.

“Don’t worry, you can return all your files!”, from text file message:

Don't worry, you can return all your files! virus

One more peculiarity of the Ghas ransomware 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 introduced the Ghas infection into the world wide web. In order to get the key and bring back the important data, the users are informed to contact the frauds via email or by telegram and to pay the ransom in the amount of $980.

The message also says that the people need to call the Ghas authors within 72 hours upon the moment of the information file encryption. The alert indicates that by doing so the people will obtain a 50% discount, for that reason, the ransom amount drops down to $490.

No matter what the quantity of the ransom is, we strongly advise that you do not pay the ransom. There is no warranty that these online scoundrels will keep their promises, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is gotten into their accounts. Thus, paying ransom frequently does not result in an effective recovery. So, the users may just lose their money for absolutely nothing.

Similarly, we urge you not to contact the frauds as they instruct. Do not move loan into their wallets. There are no applications that could crack the Ghas virus or bring back the information for free. For that reason, the only proper decision is to restore the information from possible backups (if available).
