What is Trojan.Minjen?

Trojan.Minjen was designed to mine a cryptocurrency called Monero. Our researchers at say there might be a lot of versions of it so the variant you encounter may not act the same as the one we tested. Nonetheless, it should not be that different either. Usually, such Trojans influence the infected device’s performance, so users might suspect it could be on the system if they notice the computer suddenly began to work slower. To find out more about this malicious application, we encourage you to read the rest of this article. In case you think it is on your system, we recommend checking it with a legitimate antimalware tool. The deletion steps placed below can also help you eliminate Trojan.Minjen, although if you encounter a different version of it, it is possible the instructions might not work for you.

Where does Trojan.Minjen come from?

Trojans like Trojan.Minjen are often spread through malicious websites and Spam emails. The problem is that the threats installers may not appear to be malicious, and users who open it could infect their computer without even realizing it. For instance, the launcher could look like a software installer or even a document. Therefore, even data that looks harmless should always be scanned with a legitimate antimalware tool if it originates from questionable sources.

This way, you can avoid lots of various threats. All you have to do is pick an antimalware tool you could trust and keep it up to date so that even after some time, it would be able to recognize newer malicious applications. Besides, our researchers recommend making sure your computer has no vulnerabilities (e.g., weak passwords, outdated software, and so on.) that could allow Trojans or other harmful infections slip in.

How does Trojan.Minjen work?

To start with, the malware needs to create specific files so it could function properly. Our researchers say it may start with creating four folders in %Windir%\Fonts. The version we encountered gave them short names from one or a couple of letters, for example, “a,” “b1bb1,” and so on. Additionally, Trojan.Minjen might create a Registry entry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services. Again, the version we tested, named it vmictimes, but as there could be many other variants too, they could all name the data they create differently.

Next, Trojan.Minjen should start using particular computer resources known as CPU and GPU to mine a specific cryptocurrency known as Monero. The more resources are employed, the slower the infected computer might become. For example, it might take much more time to load various programs or games. It is even possible the misuse of such resources could make the system freeze or crash. Needless to say, it is not good for the computer as it could speed up its wear. Not to mention, working on it could become difficult and annoying, which is why we advise erasing the Trojan as soon as you notice it on your device.
