How to uninstall the Strigoi Master RAT
Written by Tomas Meskauskas on (updated)
What is Strigoi Master?
A Remote Access Trojan (RAT) is malicious software that allows the attackers to monitor and control infected computers (or networks). These programs can open documents or any other files, download and install software, access the webcam, microphone, etc.
Cyber criminals use RATs to infect computers with malware and to obtain sensitive information, which could be used for malicious purposes.
Strigoi Master is written in the Java programming language and can be purchased on hacker forums. Its monthly subscription cost is US$80, and $200 for 3-months.
Research shows that Strigoi Master can restart and shut down the infected machine, execute commands via Command Prompt and PowerShell, manage files (e.g., rename, delete, move, duplicate), log keystrokes (record keyboard input), download and execute various files. Cyber criminals often employ these features to download and install cryptocurrency miners, ransomware, or other malware. They use them to obtain login credentials (usernames, email addresses, passwords), credit card details, bank account numbers, social security numbers, and other sensitive information.
Note that that they often use obtained credentials to steal personal accounts, which can then be used to send phishing emails, trick other people into making money transactions, make fraudulent transactions, purchases, and for other purposes. It is also possible that Strigoi Master could be used to access webcams and record videos to blackmail victims.
In summary, the Strigoi Master RAT can cause monetary and data loss, identity theft, loss of access to personal accounts, computer, problems with online privacy, and other issues. If you suspect its presence on the operating system, remove it immediately.

There are many different RATs online. Some examples are ObliqueRAT, Elephant RAT, Orcus RAT, and ViperSoftX RAT. The attackers have anonymous control over infected computers and victims are often unaware that they have RATs installed on their machines.
Note that RATs can be employed to perform DDoS attacks and use the infected network as a proxy server for fraudulent activities. If there is any reason to suspect that your system is infected with a RAT, scanned it with a security suite, and all detected threats should be removed immediately.
How did Strigoi Master infiltrate my computer
Malware (including ransomware) is usually distributed via malspam campaigns, unofficial software activation ('cracking') tools, Trojans, dubious file/software download sources, and fake software updating tools.
When cyber criminals attempt to distribute malware via malspam campaigns, they send emails that contain malicious attachments or download links for malicious files. Typically, they disguise their emails as official and important. If recipients open the attached file (or a file downloaded via a website link), they cause installation of malicious software.
Cyber criminals commonly attach executable files (.exe), archive files such as RAR, ZIP, PDF documents, JavaScript files and Microsoft Office documents to their emails. Software 'cracking' tools supposedly activate licensed software illegally (bypass activation), however, they often install malicious programs and do not activate any legitimate installed software.
Trojans are other rogue programs that can cause chain infections. I.e., when a Trojan is installed on the operating system, it can install additional malware.
Free file hosting websites, freeware download websites, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, and third party downloaders are examples of other sources that are used to distribute malware. Cyber criminals disguise malicious files as legitimate and regular. When users download and open them, they inadvertently infect their computers with malware.
Fake software updating tools install malicious software rather than updates/fixes for installed programs, or they exploit bugs/flaws of outdated software that is installed on the operating system.
How to avoid installation of malware?
To avoid malware spread via spam mail, you are strongly advised against opening suspicious or irrelevant emails, especially those with any attachments or links present within them.
Additionally, use Microsoft Office versions released after 2010. Malicious programs also proliferate through untrusted download channels (e.g. unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders), illegal software activation ("cracking") tools, and fake updaters.
Therefore, only download from official/verified sources and activate and update software with tools/functions provided by legitimate developers.
To ensure device integrity and user privacy, have a reputable anti-virus/anti-spyware suite installed and kept updated. Furthermore, use these programs to run regular system scans and to remove detected/potential threats.
It is to run system scans regularly. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Combo Cleaner Antivirus for Windows.
If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
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:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup. Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu".

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.
Outstanding!
