Mozart Trojan is a distinct malware which uses the DNS protocol for communications between the main engine and the hacker control server. Right now there is no information available about the hacking group which is behind the threat, nor the way it is spread.
We assume that the hackers are targeting specific networks which means that the most likely victims are going to be business and enterprise networks. In these cases the easiest way to hack a whole network would be to run direct attacks — the hackers will use an automated hacking toolkit loaded with exploit code and attempt to break in. In such environments an alternative approach would be to create and distribute payload carriers that can take forms as macro-infected documents and bundle installers. They are created by the hackers in the most popular file types — common document formats and software setup files. These files will lead to the Mozart Trojan installation when run.
These files can be easily uploaded to hacker-created sites or in SPAM email messages — both of them will be designed with the intention of manipulating the visitors into thinking that they are receiving a legitimate message and/or notification. The files can then be uploaded over to different file-sharing networks where both legitimate and pirate files are commonly shared among Internet users. Links to the Mozart Trojan data can be placed on various online communities such as forums, chatrooms, social networks and etc.
The Mozart Trojan will start its intended malicious actions when the infection starts. It will engage the main sequence by starting a local Trojan client. It will establish a secure and strong connection with the hacker-controlled server. However the direct line will not be the typical Internet stream, but the service will operate via the DNS protocol. This practically will override most intrusion detection systems and firewalls that use common signatures to detect potential threats.
The security analysis of the Mozart Trojan shows that the captured samples also include a hardcoded blacklist in order to protect itself from being discovered. The main threat is designed to undergo the common Trojan activities — steal files, take over control of victim systems and also to spy on the users.
The Mozart Trojan can be used against Internet of Things (IoT) devices and embedded systems — all of this shows that the malware can be used for sabotage purposes.
Further updates to its main engine can include other modules — ones that can be used to create in-depth profiles of the machines, steal specific kind of data and also interact with running programs and services.

- Scan for Malware
- Fix Registries
- Remove Virus Files
Step 1: Scan for Mozart Trojan with SpyHunter Anti-Malware Tool
Step 2: Clean any registries, created by Mozart Trojan on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Mozart Trojan there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.Step 3: Find virus files created by Mozart Trojan on your PC.
1.For Windows 8, 8.1 and 10.
For Newer Windows Operating Systems
1: On your keyboard press + R and write explorer.exe in the Run text box and then click on the Ok button.
2: Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.
3: Navigate to the search box in the top-right of your PC's screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be "fileextension:exe". After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:
N.B. We recommend to wait for the green loading bar in the navigation box to fill up in case the PC is looking for the file and hasn't found it yet.
2.For Windows XP, Vista, and 7.
For Older Windows Operating Systems
In older Windows OS's the conventional approach should be the effective one:
1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.
2: After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.
3: After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.
Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
