Ooza Virus Removal Guide (+Decrypt .ooza files)

Ooza – Ransomware

Ooza is a malicious software working as typical ransomware. Michael Gillespie, the popular malware researcher, first found this new name in the DJVU ransomware family.

Ooza was developed for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is successfully achieved, the users are unable to get access to them. Ooza ransomware includes its own “.ooza” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Ooza, will be entitled as “price_list.xls.ooza”. When the encryption is achieved, Ooza puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The alert mentioned by text file requesting the random os extremely comparable to the notices offered by other ransomware threats coming from the DJVU family. The warning generally indicates that the files have been secured and the only service to get access to it is to use a special standalone key. Regretfully, this declaration is definitely real.

The method to encrypt the files used by Ooza is not totally researched. Nevertheless, there is no doubt that each computer system owner might be issued a special decryption key, which is definitely distinct. It is extremely difficult to recuperate the data without the appropriate type in place.

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

One more peculiarity of the Ooza virus is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have actually released the Ooza virus into the web. In order to get the key and bring back the crucial information, the users are told to get in touch with the scams via e-mail or by telegram and to pay the ransom in the amount of $980.

The message also states that individuals should get in touch with the Ooza authors within 72 hours upon the moment of the data file encryption. The alert suggests that by doing so the people will acquire a 50% discount, for that reason, the ransom amount drops down 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 criminals will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. For this reason, paying ransom frequently does not lead to an effective recovery. So, the users may just lose their money for nothing.

Similarly, we advise you not to call the scams as they instruct. Do not move money into their wallets. There are no applications that might break the Ooza virus or restore the data at no cost. Therefore, the only appropriate choice is to restore the data from possible backups (if readily available).
