Nodersok, a New Malware That's Undetectable By Most Antivirus Programs


Nodersol is a new malware that goes unnoticed by antivirus programs and has already infected thousands of computers worldwide, mainly in Europe and the United States. The consequences could be significant, so it's best to prepare. We'll fill you in!




It is a virus that uses online advertising to sneak into computers, but without installing them. This is the reason why it is very difficult to detect it, as reported by Microsoft and the cybersecurity company Cisco.

How Noderstok Works and Spreads

The peculiarity of Nodersok (or Divergent, as Cisco has named it) is that, instead of being installed through a malicious file, it uses functions of the PC's own operating system or tools from third parties to sneak into it, while deactivating the antivirus' protective barriers. Tracking is very complicated when using programs considered by the operating system and not being stored on the computer:



How do you do it?

This virus reaches computers through online advertising, using the framework Node.js (a program that runs JavaScript outside of internet browsers) and WinDivert, an open source software that allows packet capture and diversion for versions Windows 2008, 7, 10, and 2016.

Once it infects a computer, the virus starts browsing pages with the aim of generating monetization through fake clicks on online advertising. At the same time, it uses proxy servers to continue spreading to other PCs.

How To Protect Yourself from Nodersok



Nodersok mainly attack personal computers, so we advise you to be alert. Microsoft has recommended to avoid running HTA files (or HTML applications, apps that act with HTML and CSS pages similar to .exe files). Do not save your download history. It is also advisable to keep the antivirus updated at all times to receive updates and patches that limit the vulnerability of our equipment as soon as possible.
