How to remove Syntrix remote access trojan

What kind of malware is Syntrix?

Syntrix is a RAT (Remote Access Trojan) based on the Quasar RAT (specifically, the 1.4.1 version). Trojans within this classification are designed to allow attackers to access and control devices remotely. Syntrix was developed with an emphasis on stealth. It is a multifunctional piece of malicious software with extensive data-stealing capabilities.

Syntrix malware overview

Syntrix enables remote access and control over infected machines. It infiltrates systems via a multi-stage infection chain. As mentioned in the introduction, this malware emphasizes stealth. Some of the related functionalities include the ability to bypass certain security products (such as Microsoft Defender Antivirus), runtime obfuscation (i.e., dynamic code manipulation), injector trojan traits, and utilization of several persistence-ensuring techniques.

Syntrix also supports multiple C&C (Command and Control) connection types. Upon successful infiltration, the RAT begins collecting relevant device data (including hardware and system details). It allows the attacker to view and control victims' desktops in real-time. Syntrix manages/manipulates files and running processes. It can access and modify the Windows Registry.

The RAT can log victims out of their user accounts, as well as restart and shut down the compromised device. It can record audio and video through the machine's microphones and cameras. Syntrix has keylogging abilities, i.e., recording keystrokes – a feature that can be used to obtain log-in credentials and other sensitive data.

It is also capable of extracting and exfiltrating passwords saved on various browsers and applications. Generally, RATs tend to target the following types of software: Internet browsers, password managers, email clients, VPNs (Virtual Private Networks), gaming-related programs, FTP (File Transfer Protocol) clients, cryptocurrency wallets, and so on.

It is pertinent to mention that Syntrix is a modular RAT; it can download/install additional modules to expand its capabilities. Malware developers often improve upon their software and methodologies – this, combined with Syntrix's modularity, means that its functionalities may differ between infections.

To summarize, the presence of malicious software like Syntrix on devices can result in multiple system infections, severe privacy issues, financial losses, and identity theft.

Remote access trojan examples

We have investigated numerous malicious programs; OctoRAT, ScoringMathTea, PatoRAT, STD RAT, Delivery RAT, and Propionanilide are merely some of our latest articles on RATs.

These trojans tend to be incredibly versatile. However, regardless of how malware operates – its presence on a system threatens device integrity and user safety. Hence, all threats must be eliminated immediately upon detection.

How did Syntrix infiltrate my computer?

Syntrix is available on GitHub. Thus, how it is distributed depends on the cyber criminals using it (i.e., techniques may differ between attacks). Generally, malware is proliferated using phishing and social engineering. Usually, malicious programs are disguised as or bundled with regular software/media files. They come in different formats, executables (.exe, .run, etc.), archives (ZIP, RAR, etc.), documents (PDF, Microsoft Office, Microsoft OneNote, etc.), JavaScript, and so on.

The most widespread malware proliferation methods include: backdoor/loader-type trojans, untrustworthy download sources (e.g., freeware and third-party websites, Peer-to-Peer sharing networks, etc.), drive-by (stealthy/deceptive) downloads, malicious attachments or links in spam mail (e.g., emails, DMs/PMs, etc.), malvertising, online scams, illegal software activation tools ("cracks"), and fake updates.

Some malicious programs can self-spread through local networks and removable storage devices (e.g., external hard drives, USB flash drives, etc.).

How to avoid installation of malware?

Caution is key to device and user safety. Therefore, be vigilant when browsing since the Internet is rife with fraudulent and malicious content. Do not open attachments or links found in suspicious/irrelevant communications (e.g., emails, PMs/DMs, SMSes, etc.), as they can be infectious.

Download only from official and verified channels. Activate and update software using functions/tools provided by genuine developers, as those obtained from third-parties can contain malware.

It is paramount to have a reputable antivirus installed and kept updated. Security programs must be used to perform regular system scans and to remove detected threats and issues. 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.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. 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". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings".

Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

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.
