Ooza is a rapidly spreading ransomware virus. This virus has infected a lot of computers very recently. It belongs to the Stop/Djvu family and uses a very advanced encryption algorithm. It encrypts users’ data to render all the files useless and demands ransom money for decryption.
Ooza ransomware appends the “.ooza” extension to encrypted files. For example, after encrypting a file named “myphoto.jpg”, it renames it to “myphoto.jpg.ooza”. Ransomware also leaves “_readme.txt” ransom notes in all compromised folders. The note contains a threatening message and cybercriminals’ contact details. It asks users to contact attackers via email and pay $980 in Bitcoin for the private key and decrypt software.
What is Ooza Virus?
Ooza is a very notorious file-encrypting malware. It is a dangerous and rapidly spreading malware. It uses a powerful military-grade encryption algorithm to lock files on infected PC. This virus takes all your files hostage and demands a huge sum of money as ransom.

This Ooza virus is quite effective. It can encrypt all types of files like images, videos, music, documents, databases, backups, etc. After encrypting your personal files, it also generates the “_readme.txt” file. It is a ransom note that contains information about how to contact attackers and buy decryption tools.
It will ask you that your files are encrypted but you can restore them for a price. The Ransom note says that there is but one method to recover your files. You will need to buy decryption tools and as proof of their software, they are willing to decrypt one file for free.

Working of Ooza Files Virus
Ooza silently intrudes on your PC and scans your entire hard drive for files. Then it starts the encryption of your data. This process happens so fast that users don’t even notice. Once it makes all your files inaccessible, then it leaves the ransom note in all compromised folders.

Unfortunately, there is no free Ooza Decryptor available right now. If you will try to restore your files through the backup, this virus will encrypt them too.
Contents of the “_Readme.txt” ransom note

How it infects your computer?
You must be wondering how this virus infected your PC. There are a lot of ways through which this Ooza virus has compromised your system. Cybercriminals use various ways to spread their creation online and target a huge number of computers.
Spam email campaigns are one the most used methods. Attackers create fake emails containing malicious attachments and use software to send them to lots of people at once. They buy email lists and create emails pretending to be some company or famous person. When you get such junk emails, do not open attachments without scanning them, and do not click on any links.
Cybercriminals also use software bundling to spread malware. If you are downloading any freeware application from a shady website then always use Custom or Advanced installation. They often contain hidden programs that automatically get installed without permission.
Cracked or pirated software, themes, and games also contains threat like Trojan to spoof the license. They can spread malware like Ooza virus quite easily. Also, do not visit porn or torrent websites, and avoid sharing files on unsafe networks. Clicking on misleading ads, banners, pop-ups, warnings, etc. can also lead you to suspicious sites that execute the malware on loading.
Ooza Ransomware: Threat Analysis
Why I cannot access my files?
You are not able to access your data because of a ransomware attack. Most people don’t actually know anything about ransomware infection. They have no idea about how they are not able to access any of their data. They simply think that restarting their PC would solve the problem.
But as we told you, ransomware is a file-encrypting virus. It only renders your files inaccessible to prohibit you from accessing your data. Cybercriminals demand the ransom money to give you access to your files back. So if all your files are renamed and have the “.Ooza” extension at the end, they are encrypted.
How can I restore my files?
There are ways to restore encrypted data but none of them are easy. There are some risks involved that must be considered first. Attackers are offering a decryptor that can restore your files but they are asking for a huge price. It is not easy to trust someone who has already done you harm by encrypting all your files. You cannot rely on them to keep their promise after getting paid.
You can restore your files through backup if you have one (of course). But for that, you need to remove this Ooza Ransomware from your computer first. Otherwise, it will keep encrypting your files and it can also infect your backup. So it is very important to get rid of the virus to start the recovery process.
You might think reinstalling your Windows can remove this virus. It is a bad idea because you will not be able to restore your files then. Also, this virus can hide in other drives and attack your system again. Wiping off your computer could remove this threat but again you cannot restore your data.
So you need to remove this Ooza Ransomware first from your PC. Then create a backup of your encrypted files on any USB drive or Cloud drive for safekeeping. Then proceed with the data restoration through backup. if you don’t have any backup then try data recovery software.
Why you should not pay ransom money?
Paying ransom money to buy .Ooza File decryptor is not a good idea. Attackers are only interested in stealing your money and they do not care about your files. Threatening to double the ransom fee in 72 hours is a scare technique. They want you to lose hope of restoring your data any other way.
Cybercriminals often stop communicating after getting paid. Most of the victims don’t get the decryption key after paying money. Djvu variants are also known to re-attack the previous targets. Once you use the decryptor, the virus stays on your PC and the next variant can re-encrypt your data.
You need to completely get rid of this Ooza infection to stop further damage. Decryptors don’t always work, sometimes data get corrupted, so it is not sure that you will get your files back. We advise you not to trust the attackers, no matter how desperate you are, don’t risk losing your money too.
How to protect your PC from Ooza Ransomware
Protection from threats like the Ooza virus is very crucial. You need to be ready if you don’t want to get blackmailed by cybercriminals. You just need to follow some basic rules and you will never be forced by any ransomware infection.
Use a good Anti-virus program and always scan your PC for threats. Make sure that your Windows is up to date and the firewall is active. Also, keep the latest backup of all your important files on any external USB drive or cloud drive. If any ransomware attacks your system, then you can just remove the virus and restore data from the backup.
Do not open spam emails from unknown senders. Always scan the attachments before opening them. Do not click on links that look suspicious. Never click on fake pop-up ads, banners, warnings, notifications, etc. that appear on your browser.
Do not download cracked software or games ever. Such programs often have virus payloads that will infect your system instantly. Avoid downloading hacks or illegal patches for games. Stop visiting porn or torrent sites because they often cause forced redirection to malicious sites.
