Do you know what Novter Botnet is?
If you are not careful about the advertisements you interact with, your system could become a part of the Novter Botnet without you even knowing about it. If the malicious Novter Trojan invades your operating system, it might be able to record and leak information about your operating system. Also, it could drop malicious files and perform other malicious activities. Needless to say, you want to avoid facing this malware at all costs. If you still have time, your best bet would be to install anti-malware software and stay away from all advertisements; especially the ones advertising software updates and installers. If malware has invaded your operating system, you might need to delete some files. Please continue reading to learn how to remove Novter Botnet.
According to our malware researchers, the attackers behind Novter Botnet are known by the name “KovCoreG.” These are the same attackers who stood behind the already dismantled Kovter Botnet. Kovter was spread using malvertising (malicious advertising) and exploit kits. Now they have moved on to Novter Botnet, and just like with the previous Trojan, the new one is a fileless infection too. That means that this Trojan does not need executable files to invade your operating system. Instead, the attackers employ a PowerShell script. Let’s start from the beginning. First, the user is introduced to a misleading advertisement that, for example, recommends installing an Adobe Flash update. The interface of this ad can be misleading, and you might be tricked into click the Update or Download button without thinking things through. Of course, your Adobe Flash is not updated. Instead, an HTA file is downloaded.
Once the malicious HTA file is downloaded, malicious script is loaded from a remote server and a PowerShell script is run. According to our research team, in the past, PowerShell was downloaded from yei3pallretailjobs.org, but this domain is no longer active. New ones are likely to exist in its place. When the site was active, it saved a {random name}.js file in the %TEMP% directory. The PowerShell script that is downloaded is responsible for disabling Windows Defender and Windows Update and, of course, executing Novter. The Trojan then gathers and sends information, terminates and starts processes, and downloads and deletes files. If everything goes according to plan, the infected system becomes part of the Novter Botnet. Thus far, users in the United States and Europe were most likely to be affected.
It is likely that malware was downloaded if Novter Botnet Trojan has found its way into your operating system, and so it is important for you to examine your operating system. Do not focus just on the malicious Trojan. Needless to say, inspecting the entire operating system and then removing malicious infections manually is not an easy task. Also, our research team does not recommend it. The best thing you can do is install a trusted anti-malware program that could take care of things automatically. It would quickly inspect your system and delete Novter Botnet-related malware, and it would also secure your system to keep new attackers away. Without a doubt, securing your Windows operating system is extremely important, and if you decide to figure that out at a later date, it could be too late. After all, the best tool against malware is prevention because if you keep infections away, you will not need to suffer the consequences.
