The Ooii ransomware is yet another strain of STOP ransomware that has been spotted in the wild. Ransomware is a type of malware that interferes with certain computer settings in order to reach target types of files and encode them with the help of sophisticated cipher algorithms. The main goal of data locker ransomware like .ooii is to blackmail victims into transferring hackers a ransom fee for personal files recovery.
In the event that all your valuable files appear with the extension .ooii appended to their names, it means that .ooii ransomware is currently running on your computer. Since Ooii ransomware is a threat that does not only encrypts valuable files but also disrupts system security, we recommend considering the immediate removal of all currently running malicious files and objects.
Yet another sign of an infection with this threat is a ransom message that forces you to transfer a ransom fee in cryptocurrency to hackers’ wallet. Beware that even a successful payment of the demanded ransom does not guarantee the recovery of your .ooii files.
Keep up with our removal guide and learn how to get rid of all malicious files created by Ooii ransomware. In the guide, you will also find alternative methods for .ooii files recovery.

Distribution of Ooii Ransomware Virus
Ooii virus is a new data locker ransomware that has been released in active attack campaigns against computer users worldwide. The threat could be utilizing common tactics of distribution to infect computer systems.
One of the easiest ways for criminals to spread the payload of Ooii ransomware is by attaching it to email messages that are later released in active attack campaigns. The method allows hackers to send the virus to large lists of potential victims. The attachments to malicious email spam messages usually have Word documents or other types of files that users open without hesitation. Once opened on a target host these compromised files trigger the ransomware payload and infect the device with Ooii cryptovirus. Another infection tactic related to emails is hyperlinks inserted in the content of the messages. The links are usually labelled as leading to a familiar website or a file of user interest.
Computer criminals behind this new ransomware can be using malicious sites or download portals to distribute malware of different kinds, including Ooii virus. A popular option is the use of infected documents which may be of different types ‒ spreadsheets, rich text documents, presentations and databases. They are modified to initiate the virus once the built-in scripts are run. Usually when the files are opened a notification will ask the users to run the macros (scripts). If this is done the infection follows.
The hacker-controlled sites are specialist portals that have been created either manually or automatically by the criminals behind Ooii virus. They can either directly distribute the threat by initiating various scripts or automated operations or link to such instances. Redirects are usually caused by email interaction, ad networks or other browsing activity. However one of the main sources is the availability of browser hijackers. They are malicious add-ons made for the most popular web browsers ‒ Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Microsoft Edge and Safari. Once installed they not only infect the users with the malware but also redirect the victims to a hacker-controlled site. Depending on the configuration the browser hijackers can also steal sensitive information such as any stored passwords, account credentials, history, bookmarks, form data and settings.
Impact of Ooii Ransomware Virus
The so-called Ooii virus has been detected in active attack campaigns. It is based on the code of the infamous ransomware family STOP. The code of this threat is designed to plague essential system settings with the purpose to reach target types of files and encode them with a sophisticated cipher algorithm.
The beginning of the attack is marked by the execution of the Ooii ransomware payload file. Soon after this event occurs, the threat becomes able to pass through several stages. At first, it triggers the creation of additional malicious files which support all of the following infective operations. The ransomware could either create or drop them on the system. Typically, ransomware threats like .ooii are designed to place malicious files in the following system folders – %Roaming% , %Windows% , %AppData% , %Local% , %Temp%
Afterwards, Ooii ransomware starts executing them in a predefined order. As a result, some essential system settings are heavily modified and misused by the cryptovirus. Affected could be also registry keys stored by the Registry Editor, legitimate processes and other major components that control the regular system performance.
Following system corruption, Ooii ransomware utilizes a built-in encryption module to complete its main purpose – data encryption. Since this module is designed to transform the code of targeted files with a sophisticated cipher algorithm, the files remain unusable until their code is reverted back to its original state.
Encrypted and as a consequence renamed with the extension .ooii could be the following types of files:
- Documents
- Archives
- Backups
- Databases
- Images
- Videos
- Music
Following data corruption, Ooii STOP drops a text file which contains a ransom message. This file appears on the screen as its purpose is to blackmail you into paying hackers a ransom fee. Here is what its text usually informs:
ATTENTION!

Remove Ooii Ransomware Virus and Restore PC
Please note that paying the requested ransom fee to cybercriminals does not really solve your problem with Ooii crypto virus. In fact, you only encourage hackers to continue spreading ransomware of this kind. Instead, you must remove the threat immediately, and only then look for optional ways to recover your data.
WARNING! Manual removal of Ooii ransomware virus requires being familiar with system files and registries. Removing important data accidentally can lead to permanent system damage. If you don’t feel comfortable with manual instructions, download a powerful anti-malware tool that will scan your system for malware and clean it safely for you.
