How to eliminate DarkWatchman RAT
Written by Tomas Meskauskas on
What kind of malware is DarkWatchman?
DarkWatchman RAT in detail
According to the malware researchers who have discovered DarkWatchman, this malware is a RAT paired with a keylogger (keystroke logger) written in the C# programming language. Both parts of the malware are being stored in the system registry to avoid detection. DarkWatchman can execute EXE files, load DLL files, execute PowerShell, WSH commands and execute commands on the command line and via WMI.
Also, DarkWatchman can upload files from the infected computer to the C2 server (and update the C2 server). Cybercriminals behind DarkWatchman can remotely stop, remove and update both components (RAT and the keylogger), make the RAT run on system startup. They also can delete shadow copies (if the user has admin permissions).

If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.
These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software. To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
