Luez Virus Ransomware

Luez is a malicious software application working as common ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.

Luez was developed for the sole purpose to encrypt all popular file types. Realistically, as quickly as the encryption is successfully accomplished, the users are unable to get access to them. Luez ransomware includes its own “.luez” to all the encrypted files. For example, the file “price_list.xls”, when modified by Luez, will be entitled as “price_list.xls.luez”. When the encryption is accomplished, Luez puts its own unique text document (_readme.txt) into all the folders that store the encrypted files.

The message stated by _readme.txt asking for the random os very similar to the alerts given by other ransomware risks belonging to the DJVU family. The caution basically shows that the data has been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.

The technique to encrypt the files utilized by Luez is not totally looked into. However, there is no doubt that each computer system owner might be provided a special decryption key, which is absolutely special. It is incredibly difficult to recover the information without the suitable key 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 Luez ransomware is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the scoundrels who have introduced the Luez virus into the world wide web. In order to acquire the key and bring back the essential information, the users are informed to get in touch with the scams through email or by telegram and to pay the ransom in the amount of $980.

The message likewise says that individuals should call the Luez authors within 72 hours upon the moment of the information encryption. The alert suggests that by doing so individuals will obtain a 50% discount, for that reason, the ransom quantity falls to $490.

No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no assurance that these online criminals will keep their guarantees, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. Thus, paying ransom often does not lead to an effective healing. So, the users may just lose their money for absolutely nothing.

Similarly, we advise you not to contact the scams as they advise. Do not transfer loan into their wallets. There are no applications that could break the Luez ransomware or bring back the data for free. For that reason, the only correct choice is to bring back the information from possible backups (if available).
