The Nodera Ransomware is a ransomware that is designed to infect Node.JS servers and platforms. There is no information available about the hacking group behind it. It features several advanced modules which are designed to cause a lot of system issues.
Once the Nodera Ransomware has started it will execute its built-in sequence of dangerous commands. Depending on local conditions or the specific hacker instructions various actions will take place. The file encryption will begin after them — the encrypting component will use a built-in list of target file type extensions. In the end the victim files will be renamed with a designated extension.

The Nodera virus is one of the first ransomware specifically targeting Node.js framework installations. This is an unusual malware as this is a specific technology that is used in web services and products to deliver end-user and backend applications. The way the Nodera virus is designed is to act against specific host platforms that provide this functionality. At the moment the majority of attacks are designed to intrude onto Microsoft Windows servers. However future updates of the Nodera virus can modify it so that it can act against other popular web server platforms and operating systems: namely Mac, Linux and embedded systems.
At the moment the main distribution method is the sending of malware HTA files or dangerous ads. This means that the hacking group will probably use web methods such as the creation of phishing pages or the sending of fake email messages in a SPAM-like manner.
One of the collected samples associated with the Nodera virus was a VBS Script which is the payload delivered by HTA and JavaScript carriers which will trigger the infection. This will create a special directory in the APP Data Local folder of the currently logged in user where the virus will reside. The virus will be downloaded by the initial infection engine and all prerequisite modules will be delivered alongside it. According to the available research information one of the first steps is the modification of the Windows Registry by creating special strings for the Nodera virus. It will register itself under the strings used by key system and software components — Microsoft Office apps (if installed), Startup (where the automatic boot programs are placed) and Windows (reserved for use by the operating system). This will ensure that the virus will be run every time the computer is started. Due to the multiple manipulation of the entries the recovery will be very difficult.
The virus will finally be executed with a complex parameters string which will feature targeted options settings based on the infected host. The JavaScript also includes a custom setup of the Bitcoin Address which can vary depending on local conditions. Using certain system environment variables the main engine will allocate custom extension names which will vary from system to system. The files will be renamed according to this extension.
Using certain system environment variables the main engine will allocate custom extension names which will vary from system to system. The files will be renamed according to this extension.
In the end of the virus processes two files will be dropped onto the systems — one of it is the ransom note created in a file called How-to-buy-bitcoins.html while the other is a BAT file called Decrypt-your-files.bat which will run the decryption when the required parameters are set. As always the victims will be blackmailed to pay the criminals a restore fee. Not only will a common layout and contents be presented to the users, but also a timer which serves as an additional manipulation move.

Step 2: Uninstall Nodera Virus and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Nodera Virus on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Nodera Virus there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Nodera Virus
Step 5: Try to Restore Files Encrypted by Nodera Virus.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Nodera Virus aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
