What is Nibiru ransomware?

Nibiru ransomware – data-locking malware that threatens to crash the infected computers if ransom is not paid

Nibiru ransomwareNibiru ransomware is a file locking virus that asks for $4.5 million ransom

Nibiru ransomware is a malicious program designed to encrypt all personal data on the computer and the connected networks and then demand ransom for its return. Once inside the system, it encrypts all personal pictures, videos, documents, archives, and other files by using a combination of AES + RSA encryption algorithms, which also appends a .Nibiru extension in the process. Victims can no longer access these files and require a unique key that only cybercriminals who deployed the ransomware have access to.

Once the encryption is complete, the Nibiru virus does not provide a text-based ransom note (like it is typical for other strains) but instead locks the screen of all the infected machines. There, users can see a message from the attackers – it claims that $4.5 million ransom needs to be paid to recover the locked data. For communication purposes, malicious actors also provide an email They also claim that the decryption key required for file recovery will be deleted after 52 hours of the infection.

Name Nibiru ransomware

Extension Files appended with .Nibiru extension, e.g., “picture.jpg” is turned into “picture.jpg.Nibiru”
Ransom note There is no ransom note file delivered. Instead, users are presented with a lock-screen titled “Form2” – it prevents any interaction with the Windows operating system
File recovery If no backups are available, recovering data is almost impossible. Nonetheless, we suggest you try the alternative methods that could help you in some cases – we list them below
Malware removal Perform a full system scan with powerful security software, such as SpyHunter 5Combo Cleaner. Since the infection locks the screen, you should access Safe Mode with Networking as explained below and then perform a scan from there
System fix Malware can seriously tamper with Windows systems, causing errors, crashes, lag, and other stability issues after it is terminated. To remediate the OS and avoid its reinstallation, we recommend scanning it with the FortectIntego repair tool

Nibiru ransomware belongs to the category of data-locking malware specializing in encrypting corporate networks and servers – a tactic known as “Big Game Hunting.” These threats are typically operated by large-scale cybercriminals and focus on bigger ransoms rather than the smaller ones, unlike regular consumer-focused threats such as Foqe.

Since the malware targets companies rather than regular users, it is highly likely that the threat is propagated via the following methods:

  • Remote Desktop (RDP) connections that are open to the internet
  • Targeted phishing emails
  • Exploits and vulnerabilities.[1]

Before locking data, cybercriminals snoop around the network and move laterally, obtaining the credentials of relevant Windows accounts. During this time, they also extract various sensitive information/files and transfer them to a remote server. Only then Nibiru virus is deployed.

Once inside, it modifies the Windows registry and deletes Shadow Copies to prevent a quick data recovery – it infects the whole network and encrypts all files located on the connected computers. As a result, these files obtain .Nibiru extension and can no longer be accessed.

Nibiru file virus developers have a very straightforward approach when it comes to the payment. They do everything to ensure that victims would be persuaded to pay the ransom. The lock screen contains several threats about data decryption – crooks say that trusting them is the only option to recover files, and, if the ransom is not paid on time, they will publish the collected sensitive information, which will also ruin the company's reputation and cost millions of dollars to recover from.

Malicious actors also say that if the ransom is not paid within 52 hours, the decryption key will be permanently deleted:

Cybersecurity experts[2] do not recommend paying a ransom, and instead, use alternative recovery methods we provide below. However, it is important to perform Nibiru ransomware removal before the file recovery can be successful, as the virus will continue to encrypt the incoming files. Besides, if the malware is not deleted, access to a machine is impossible due to the lock screen.

It is important to note that the malware affects several parts of the Windows operating system, e.g., it disables the Task Manager. These changes might be difficult to reverse, so we recommend using FortectIntego repair software after you remove Nibiru ransomware virus from the infected computers. To do that, you should disconnect each of the machines from the network, access Safe Mode with Networking, and then launch a scan with SpyHunter 5Combo Cleaner, Malwarebytes, or another powerful security software.

Recover .Nibiru files washout paying criminals

Although cybercriminals are using scare tactics to may victims pay, it is important to note that this malware strain is relatively new, the sum that is being asked for is huge, and there is still no guarantee that .Nibiru file decryptor will be delivered once the ransom is paid.

Instead of communicating with the attackers, you should use backups to recover .Nibiru files. If no backups were retained or were encrypted during the infection process, there are very few options to retrieve all data successfully. Nonetheless, you can try the following methods:

  • Using third-party recovery software;
  • Trying built-in Windows restore points.

For the above to work, malware must fail to delete Shadow Volume Copies, however, which does not happen that often.

Since Nibiru ransomware focuses on attacking corporations and harvests sensitive details that might contain corporate secrets, some victims might be inclined to pay to remove .Nibiru extension and prevent a data breach.[3] As noted, this is quite risky, as the ransomware developers ask for $4.5 million in Bitcoin.

Use powerful anti-malware to remove Nibiru ransomware

The first issue that users might encounter during Nibiru ransomware removal is the lock screen. Since the virus disables the Task Manager, it is impossible to shut it down or use any other Windows features. To bypass this functionality, you should access Safe Mode with Networking and scan the device with SpyHunter 5Combo Cleaner, Malwarebytes, or another anti-malware to ensure that all the malicious components are deleted fully.

Before you attempt to remove Nibiru ransomware virus from each of the machines, you should disconnect them from the network to ensure that infection would not spread repeatedly. Experts also advise using PC repair tools such as FortectIntego if the infection managed to damage some Windows system files, and some of the infection damage could not be reverted with security software.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Nibiru from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by Nibiru, you can use several methods to restore them:

Data Recovery Pro might sometimes help your retrieve at least some of your files

In some cases, third-party recovery software can recover some files that were locked by a ransomware virus.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Nibiru ransomware;
  • Restore them.

Windows Previous Versions Feature can help to recover files one-by-one

If the Nibiru files virus failed to remove Shadow Copies, you might be able to recover some files.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer might help

ShadowExplorer could automate the recovery process if malware failed to operate correctly during the infection stage.

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

No decryptor is currently available.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Nibiru and other ransomwares, use a reputable anti-spyware, such as FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
