The Nodersok Trojan is a dangerous malware threat which is designed mainly for Microsoft Windows computers. It can be acquired from various sources, every attack campaign can focus on one specific tactic. Usually virus infections like this one are made by interacting with an infected file — this can be either a macro-infected document or a hacker-made software installer. They are often made by taking the legitimate files from their official sources and modifying them with the necessary virus code. Other data can also be affected. All kinds of other data may be used as well — this includes malicious plugins for web browsers and etc. In other cases the hackers can use a direct attacks that will look for system vulnerabilities and weaknesses. If any are found then the Nodersok Trojan will be installed.
This particular threat is known for being spread using a multitude of weaknesses. It is set against both end users and servers. After the infection has been made the Nodersok Trojan can download other threats, launch multiple dangerous modules and install a cryptocurrency miner which will run a sequence of performance-demanding tasks.

Nodersok Trojan — How Did I Get It
The Nodersok Trojan is an advanced type of malware that is devised by an unknown hacking group and is being sent to its intended targets in a large-scale campaign in September 2019. One of the distinct features about it is that it is designed to target the following groups of networks: private and government organizations, education and healthcare institutions, professional services and the financial and retail sector. There is no information yet about the main method used by the hackers behind it but we anticipate that is one of the following:
- Direct Attacks — The hackers can use automated toolkits in order to search for weaknesses in the systems. If such are found the engines will automatically penetrate the defenses so that the malware will be insalled on the computers.
- Payload Delivery — The hackers can embed virus installation scripts in various files including documents and application installers. They can take the form of popular software or important files, but when they are launched the built-in macros will be launched which will lead to the virus deployment.
- Previous Attack — The Nodersok Trojan can be planted onto the target devices by other viruses which have already impacted the systems.
- Social Engineering Campaigns — The hackers can use phishing tactics and manipulation in order to coerce the recipients into clicking on the shown links and executable files.
Nodersok Trojan — Capabilities
As soon as the Nodersok Trojan is installed on a given computer it will start to execute its built-in behavior pattern. One of the distinct features associated with this particular threat is that it delivers and uses two legitimate tools — a Windows-based Node.js framework implementation and a network packet capture library called WinDivert. This gives security researchers reasons to believe that the hacking collective behind the threat is experienced enough to integrate the necessary modules that use them.
One of the most common consequences is the designation of the hosts as a zombie proxy — hosts that are used to relay hacker instructions and malware. The network connections are done via the service providers of the hacked computers which anonymizes the fact that they originate from someone else. This is used in cases such as distributed denial of service attacks which are used mainly for sabotage purposes.
The security analysis shows that many of the samples will download an HTML application with a random name which probably means that many of the infections originate from browsing malware online ads. A content analysis shows that they are likely hosted on the legitimate cloud hosting network Cloudfront which suggests that the hackers are utilizing it to host and generate hundreds of sites.
To launch the built-in modules the virus will use the PowerShell execution. It is used not only to call the additional scripts, but also to disable the Windows Defender service, as well as Windows Update feature.
This means that potentially the Nodersok Trojan can also be used to launch components such as information gathering — it can hijack user information that can be used for crimes such as financial abuse and identity theft. If any machine data is hijacked it will be used to create a complete profile of the host computer. This will lead to the creation of an unique ID that is going to be associated with every contaminated device.

Preparation before removing Nodersok Trojan.
Before starting the actual removal process, we recommend that you do the following preparation steps.
- Make sure you have these instructions always open and in front of your eyes.
- Do a backup of all of your files, even if they could be damaged. You should back up your data with a cloud backup solution and insure your files against any type of loss, even from the most severe threats.
- Be patient as this could take a while.
- Scan for Malware
- Fix Registries
- Remove Virus Files
Step 1: Scan for Nodersok Trojan with SpyHunter Anti-Malware Tool
Step 2: Clean any registries, created by Nodersok Trojan 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 Nodersok Trojan 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.Step 3: Find virus files created by Nodersok Trojan on your PC.
1.For Windows 8, 8.1 and 10.
For Newer Windows Operating Systems
1: On your keyboard press + R and write explorer.exe in the Run text box and then click on the Ok button.
2: Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.
3: Navigate to the search box in the top-right of your PC's screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be "fileextension:exe". After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:
N.B. We recommend to wait for the green loading bar in the navigation box to fill up in case the PC is looking for the file and hasn't found it yet.
2.For Windows XP, Vista, and 7.
For Older Windows Operating Systems
In older Windows OS's the conventional approach should be the effective one:
1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.
2: After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.
3: After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.
Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
