Xoza Virus Removal Guide (+Decrypt .xoza files)

Xoza Virus – Details

Xoza is a malicious software functioning as common ransomware. Michael Gillespie, the well-known virus researcher, very first found this new name in the DJVU ransomware family.

Xoza was created for the sole function to encrypt all popular file types. Realistically, as soon as the encryption is successfully accomplished, the users are not able to get access to them. Xoza ransomware adds its own “.xoza” to all the encrypted data. For instance, the file “price_list.xls”, once modified by Xoza, will be entitled as “price_list.xls.xoza”. As soon as the encryption is accomplished, Xoza puts its own unique text file (_readme.txt) into all the folders that store the encrypted files.

The alert specified by _readme.txt asking for the random os very comparable to the notices provided by other ransomware risks belonging to the DJVU family. The warning generally shows that the files have been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.

The method to encrypt the files used by Xoza is not entirely investigated. However, there is no doubt that each computer system owner may be provided a special decryption key, which is definitely special. It is very hard to recuperate the data without the proper type in location.

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

One more peculiarity of the Xoza infection 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 actually introduced the Xoza virus into the web. In order to obtain the key and restore the essential information, the users are informed to get in touch with the scams by means of e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise says that individuals should contact the Xoza authors within 72 hours upon the moment of the data file encryption. The alert shows that by doing so the people will acquire a 50% discount, therefore, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we highly recommend that you do not pay the ransom. There is no assurance that these online scoundrels will keep their guarantees, so they may not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom typically does not lead to a successful recovery. So, the users may merely lose their money for nothing.

There are no applications that might crack the Xoza ransomware or bring back the information for free. Therefore, the only right decision is to bring back the information from possible backups (if offered).
