The Muhstik Malware

Muhstik is considered a malicious program commonly known as a Trojan Horse. Malware like Muhstik is tied to a myriad of security problems, the most dangerous one being a potential ransomware infection.

As you probably know, the Trojan Horse infections are some of the nastiest and the most difficult to handle among all the malware representatives. They are very versatile and the hackers who create them can use them for so many harmful tasks, that you oftentimes cannot know what kind of damage to expect. The main problem with these threats is that they are so sneaky and could easily hide in different system locations and launch different malicious activities in the background without showing any visible symptoms. Therefore, you should definitely not try to handle them on your own if you don’t have sufficient knowledge or reliable removal instructions and a trusted professional removal tool that can safely detect and remove them.

Muhstik Botnet

According to researchers Muhstik is a malware of the Trojan Horse variety. A threat such as Muhstik is considered quite serious and should be regarded as a high priority risk.

Muhstik, in particular, is an advanced Trojan-based infection which may have extremely harmful abilities. The criminals who have control over it can use it to spy on their victims, hack into the webcam or mic and collect sensitive audios, videos, screenshots and other data that could later be used in blackmailing schemes, psychological harassment and other forms of cyber terror. And this is not everything, such a malicious piece of software can effectively weaken the security of the infected computer by creating vulnerabilities and blocking the existing antivirus protection. Muhstik may secretly insert other malware such as Ransomware or Rootkits and act as a backdoor for different viruses and sketchy apps. It may also collect passwords and other sensitive data and send it to remote criminal servers or directly provide the hackers with remote control over the machine. The Trojan may also corrupt important files and software, replace certain components of the OS, delete important information or totally corrupt everything that is stored on the HDD. The worst part is that you may not even notice when and how your PC gets compromised because there are usually no visible indications that can give the presence of the Trojan Horse away. At a certain point, however, if the malware gets active, you may start to experience sluggishness in the system, frequent software errors, crashes or some other form of unusual behavior which may indicate much more serious damage to the OS. That’s why, if you notice something unusual, it is best to use a professional scanner to quickly check your entire machine for potentially malicious background activities and immediately remove anything that the software detects as a threat. Alternatively, you can use a manual Removal Guide like the one below, which could assist you in finding and deleting the harmful code but it is not advisable to experiment with it if you are not sure what exactly you need to remove.

    • Hi,
      I apreciate the work you’ve put into this guide. I came here because the title mentions QNAP. My QNAP NAS is infected with this trojan, my PC is clean (fresh install on a new SSD).
      Do you have a workflow to remove the trojan from the QNAP? If not, could you please change the title?
