Gyew Virus – Details
Gyew is a destructive software application working as common ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.
Gyew was created for the sole function to encrypt all popular file types. Realistically, as soon as the file encryption is successfully achieved, the users are unable to get access to them. Gyew ransomware includes its own “.gyew” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Gyew, will be titled as “price_list.xls.gyew”. As soon as the encryption is accomplished, Gyew puts its own special text file (_readme.txt) into all the folders that keep the encrypted files.
The alert specified by text file asking for the random os really similar to the alerts given by other ransomware dangers coming from the DJVU family. The warning basically shows that the information has been secured and the only option to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely real.
The technique to encrypt the files used by Gyew is not completely investigated. Nevertheless, there is no doubt that each computer system owner may be issued an unique decryption key, which is definitely distinct. It is exceptionally hard to recover the information without the suitable type in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Gyew ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the scoundrels who have released the Gyew virus into the internet. In order to get the key and restore the crucial information, the users are told to get in touch with the scams via email or by telegram and to pay the ransom in the amount of $980.
The message likewise says that individuals must contact the Gyew authors within 72 hours upon the moment of the information encryption. The alert suggests that by doing so the people will obtain a 50% discount, for that reason, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we highly encourage that you do not pay the ransom. There is no assurance that these online crooks will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is gotten into their accounts. For this reason, paying ransom typically does not result in a successful healing. So, the users may merely lose their money for absolutely nothing.
Similarly, we prompt you not to call the scams as they advise. Do not transfer money into their wallets. There are no applications that could break the Gyew virus or restore the data at no charge. For that reason, the only appropriate decision is to bring back the information from possible backups (if readily available).
