Nodersok is the fileless malware that turns systems into proxies to perform click-fraud

Nodersok malwareNodersok malware is the virus used to attack thousands of machines in one attack. Nodersok malware is the Trojan already known for its malicious campaigns on thousands of computers. The malware named differently by various researchers, while Microsoft dubbed the strain Nodersok, Cisco Talos research team named this trojan Divergent.[1] Either way this malware is extremely dangerous and is designed to run on Windows computer to infect machines using various techniques. Each virus attack depends on specific tactics but, in most cases, threat focuses on infected files that can be installed form a macro-infected document or a hacker-altered installer.

The initial Nodersok Trojan malware campaign is focused on a copy of Node.js that once downloaded and installed, converts systems into proxies. Malware infected thousands of machines over the course of weeks in Europe and the U.S. This primary attack was focused on home users, although organizations and industries like education, businesses, professionals in finance, healthcare, retail also got affected.[2] However, recent reports state that the malware is still active and might get updates, so trojan can attempt to get on machines belonging to any user.

Nodersok malware attack starts when an infected file comes to the machine because usually, such infections modify legitimate files, including malicious code. In most cases, these files are macro-infected documents or software installers made by hackers. The virus also takes advantage of system vulnerabilities, and other weaknesses, so direct attacks are successful. This trojan can launch multiple dangerous modules and install threats like cryptocurrency miners and run different tasks or processes in the background. 

This Nodersok/ Divergent malware has many modules triggered on different infection stages:

  • PowerShell module that disables OS updates, antivirus tools, security functions;
  • A binary shellcode tries to perform elevation of privilege;
  • A shellcode that runs Windivert packet filtering engine;
  • JavaScript module that is written in Node.js framework that turns the machine into a proxy.

Unfortunately, Nodersok Trojan spreads via malicious sites and installs HTA files on the machine that once opened can lead to damage and other serious issues, so it is not intrusive enough to appear on the screen immediately. Although Mac users cannot be affected by this malware, trojan infects most of the devices based on Windows OS.

This fileless virus can relay malicious traffic for nefarious means, so once the Nodersok/ Divergent malware is on the system, earning money using your device for various fraudulent activities becomes the main goal of cybercriminals behind the threat. Two different names are based on different analyses and researches, but malware acts the same and can lead to numerous malware infections if left running on the system.  Nodersok virusNodersok Trojan is the malware installing malicious files on the targeted computers to integrate necessary modules. Nodersok fileless malware is the type of threat that infects the site victims tend to visit. Outdated plugins or browser content are used, and the malware relies on particular vulnerabilities of those outdated parts. When this is achieved successfully, the virus starts running the payload in the memory of a targeted device and infects the system to achieve further goals.

Nodersok Trojan is working in the background of your computer and disrupts the usage of the machine this way, but you cannot notice that since it is not invasive. Virus downloads HTA files on the computer before starting the infection process, and then various applications start running malicious scripts injected by the malware. 

This is the method used particularly for persistency because using safe and legitimate applications for malicious processes keeps Nodersok malware removal difficult. Anti-malware tools cannot indicate the process or the program as malicious since the app is initially safe. Unfortunately, this malware uses files associated with Windows Defender itself, so it appears especially safe for the system and security tools.

However, although you need to remove Nodersok malware as soon as possible, it is more difficult to spot the infection on time. According to initial versions and sample analysis, this virus is yet to get extremely dangerous, but right now, it is not that notorious of malware. It is possible that trojan is used to proliferate more advanced malware on the machine further once the scrips start running on the device.

It is extremely important to delete the Nodersok Trojan as soon as possible, so the virus doesn't escalate to the even worse stage. However, there are not many symptoms that can be observed by the victim. You may potentially notice some system slowdowns, but this is not that typical when the PC is usually fast. An anti-virus scan is the best method that can show issues and detect malware on the machine. Get Reimage Reimage Cleaner Intego or a different tool designed for fighting threats. Nodersok trojan malwareNodersok malware belongs to a trojan category due to the silent processes and using of the denial of service attacks.

Ways to avoid getting infected by malware and virus script delivery methods

This malware involves malicious files and multiple tactics that get used to delivering those infected materials. Malware can rely on security flaws and vulnerabilities that help hackers to spread their products directly on the targeted machine.

These are the tips for your behavior online when you want to avoid infiltrations of such malicious trojans:

  • Don't click on commercial banners without considering the malware possibility. Experts[3] always note that intrusive ads have more to them besides annoying you.
  • Stay cautious when installing programs and applications. Less reliable sites tan include add-ons with security flaws.
  • Visit trustworthy sites and stay away from torrent pages.
  • Update your security tools and anti-malware protection apps. Malware gets updates and new versions, so your tools should get updated too.

This is how trojan affects the security of your device, and spreads other malware, exposes the system to vulnerabilities. From there, time is a very important factor for Nodersok malware removal.
