ZynorRAT Malware Removal Guide (Linux/Windows)

What Is ZynorRAT?

ZynorRAT is a recently discovered Go-based remote access trojan (RAT) that targets Linux (and Windows) systems. On Linux, it has the following behaviors:

• It runs as a 64-bit ELF executable compiled for x86-64 architecture.
• Once on a Linux host, it performs system enumeration (host name, current user, public IP via “api.ipify.org”, etc.).
• It supports a set of built-in commands via its Telegram-based command & control (C2) interface, such as /fs_list (list directory contents), /fs_get (send a file back to the attacker), /proc_list (list running processes), /proc_kill (kill a process by its PID), /capture_display (take screenshots), /metrics (profile system), etc.
• For persistence on Linux, it uses systemd user services, placing a service file in ~/.config/systemd/user/system-audio-manager.service so it can restart automatically and survive logins.
• If a received command does not match one of its predefined commands, it falls back to executing shell commands via bash -c <command>, allowing arbitrary code execution.

How to Detect and Remove ZynorRAT on Linux

• Check for unusual processes: Run ps aux | grep system-audio-manager or look for suspicious ELF binaries running under your user account.
• Inspect persistence: Verify if a malicious service file exists in ~/.config/systemd/user/system-audio-manager.service. If found, disable it using systemctl --user disable system-audio-manager.service and remove the file.
• Monitor network traffic: Look for outbound connections to Telegram API endpoints or unknown IPs/domains, which may indicate C2 communication.
• Delete suspicious binaries: Locate and remove the dropped executable (often in ~/.local/ or /tmp/).
• Run an anti-malware scan: Use a Linux-compatible anti-malware tool such as ClamAV or Falcon CrowdStrike to ensure full cleanup.
• Harden the system: Update all packages, restrict user permissions, and enable SELinux or AppArmor to reduce risk of reinfection.

How to Detect and Remove ZynorRAT on Windows

• Check for unusual processes: Open Task Manager and look for suspicious executables or processes with random names consuming CPU/memory.
• Inspect persistence: Check msconfig startup entries, Task Scheduler, and registry keys under HKCU\Software\Microsoft\Windows\CurrentVersion\Run for references to unknown executables.
• Scan for dropped files: ZynorRAT may store its payload in %AppData%, %Temp%, or C:\Users\[username]\AppData\Local\. Remove suspicious files.
• Monitor network connections: Use netstat -ano or tools like TCPView to detect unauthorized connections to Telegram or unknown servers.
• Run a full anti-malware scan: Use tools like SpyHunter or Microsoft Defender Antivirus to detect and eliminate the RAT and related files.
• Apply system hardening: Keep Windows updated, enable real-time protection, and disable unnecessary administrative accounts.

Preparation before removing ZynorRAT.

Before starting the actual removal process, we recommend that you do the following preparation steps.

• Make sure you have these instructions always open and in front of your eyes.
• Do a backup of all of your files, even if they could be damaged. You should back up your data with a cloud backup solution and insure your files against any type of loss, even from the most severe threats.
• Be patient as this could take a while.

• Scan for Malware
• Fix Registries
• Remove Virus Files

Step 1: Scan for ZynorRAT with SpyHunter Anti-Malware Tool

1. Click on the "Download" button to proceed to SpyHunter's download page.

Malware Removal Tool

---

It is recommended to run a scan before purchasing the full version of the software to make sure that the current version of the malware can be detected by SpyHunter. Click on the corresponding links to check SpyHunter's EULA, Privacy Policy and Threat Assessment Criteria.

---

2. After you have installed SpyHunter, wait for it to update automatically.

---

3. After the update process has finished, click on the 'Malware/PC Scan' tab. A new window will appear. Click on 'Start Scan'.

---

4. After SpyHunter has finished scanning your PC for any files of the associated threat and found them, you can try to get them removed automatically and permanently by clicking on the 'Next' button.

If any threats have been removed, it is highly recommended to restart your PC.

Step 2: Clean any registries, created by ZynorRAT 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 ZynorRAT there. This can happen by following the steps underneath:

---

1. Open the Run Window again, type "regedit" and click OK.

---

2. When you open it, you can freely navigate to the Run and RunOnce keys, whose locations are shown above.

---

3. You can remove the value of the virus by right-clicking on it and removing it. 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 ZynorRAT 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.
