Moreover, some samples are also able to deliver other malicious programs to the system.
Trojan:Win32/LummaC!MTB Detection Overview
The Trojan:Win32/LummaC!MTB detection you can see in the lower right side is shown to you by Microsoft Defender. That anti-malware software is pretty good at scanning, however, prone to be generally unreliable. It is defenseless to malware invasions, it has a glitchy user interface and problematic malware removal features.

Having Trojan:Win32/LummaC!MTB malware on your PC is not a pleasant thing from any point of view. The worst problem is that you will barely see anything wrong.

After that, it will be practically impossible to uncover the flow of events and understand how your accounts were hacked.

Is Trojan:Win32/LummaC!MTB dangerous?
As I have pointed out earlier, any malware is dangerous. And Trojan:Win32/LummaC!MTB is not even close to distracting you rather than harming. The most misleading quality of LummaC is the fact you cannot observe its activity in any way, other than with the use of anti-malware software scanning. And while you are in the dark, cybercriminals who deployed their malware to your computer are starting to count the money. Darknet offers numerous opportunities to sell malware logs for a hefty sum – especially when these logs are new. And you’d better not imagine what will happen to your accounts when other cybercriminals will put their hands on your login credentials.
However, situation may have much faster flow. In some situations, crooks are spreading their virus precisely to the user they are trying to rob. Spyware is priceless when it comes to collecting login credentials, and some examples target precisely at banking accounts or crypto wallets. One may say, giving spyware a run equals to sending all your money to criminals.
