How to remove LabubaRAT malware from the operating system

What kind of malware is LabubaRAT?

LabubaRAT is a Remote Access Trojan (RAT) written in the Rust programming language that disguises itself as NVIDIA software. The analyzed sample was named nvidia-sysruntime.exe and carried fake NVIDIA version information and branding to make it appear like a legitimate system tool.

According to research published by Blackpoint Cyber, LabubaRAT gives operators remote control over infected machines. Once active, it allows attackers to execute commands, capture screenshots, manage files, and route traffic through the victim's internet connection using a SOCKS5 proxy.

The malware is designed with a flexible configuration model that allows different operators to deploy the same binary with unique settings - server addresses, API keys, and campaign identifiers - without recompiling it. This points to a Malware-as-a-Service (MaaS) setup where LabubaRAT is made available to multiple criminal customers.

LabubaRAT overview

LabubaRAT contacts its operators through an encrypted HTTPS channel, regularly polling a remote server for new instructions. The malware's command-and-control (C2) panel was identified under the name "LabubaPanel". Local state is stored in a SQLite database file named nvctr_sys.db. If the primary channel is unavailable, it falls back to routing requests through Windows WebView2 or through DNS tunneling with Base32 encoding.

When it first runs, LabubaRAT profiles the infected computer and sends a registration report back to the attacker's server. This includes the hostname, CPU model, RAM, public IP address, connection type, and domain membership. The malware also scans for installed browsers and active security products, including Microsoft Defender, CrowdStrike, SentinelOne, Sophos, Malwarebytes, Kaspersky, and several others.

LabubaRAT's capabilities

Operators can send commands that execute in the Windows Command Prompt, in PowerShell, or as JavaScript through the Windows Script Host. Results are sent back to the operator's panel in real time, giving the attacker a direct interactive view of the system.

LabubaRAT includes file management functions that let operators upload files to the infected machine, download files from it, delete files, create directories, and compress or extract archives. These capabilities allow an attacker to drop additional payloads, steal documents, or modify files on the system.

Screen capture is also supported - the RAT can silently take screenshots of the victim's desktop on demand. The SOCKS5 proxy function lets attackers route their own traffic through the victim's internet connection, effectively masking the attacker's origin or giving them access to network resources visible only from the victim's location.

Persistence and evasion

LabubaRAT establishes persistence by adding an entry to the Windows Registry under the current user's Run key (HKCU\Run), which causes it to launch automatically each time the user logs in. The malware accepts an --install argument to create this entry and an --uninstall argument to remove it.

For evasion, the sample is built as a legitimate-looking 64-bit Windows application carrying fake NVIDIA metadata. It uses a mutex named Local\NVIDIAContainerMonitor_SingleInstance to prevent multiple copies from running simultaneously - a behavioral trait of real software that helps it blend in with genuine NVIDIA processes.

Configuration values - including the C2 server address, API keys, and operator group tag - can be passed as Base64-encoded command-line arguments, making them harder to spot during basic log review. Additional settings are read from environment variables with the ZM_ prefix.

Conclusion

LabubaRAT gives attackers full remote control over infected machines. They can execute commands, capture the screen, manage files, and route traffic through the victim's connection - all while remaining completely invisible to the victim.

Its use of fake NVIDIA branding, registry-based persistence, and multiple fallback communication channels makes it a stealthy and resilient threat. LabubaRAT should be removed from any affected system immediately.

More examples of RATs are RemotePE, MODBEACON, and Navi.

How did LabubaRAT infiltrate my computer?

Blackpoint Cyber researchers analyzed a LabubaRAT sample named nvidia-sysruntime.exe that posed as the NVIDIA Container Runtime Monitor. It carried authentic-looking NVIDIA version information and branding to make users believe it was a genuine driver or system component.

Malware that impersonates well-known software is typically spread through fake download websites designed to look like official vendor pages, through phishing emails with malicious file attachments, and through links sent in social media or messaging app conversations.

Other common infection paths include unofficial software downloads, pirated programs, and cracks or key generators. Attackers often disguise malicious files as well-known system utilities or popular applications because users are more likely to run them without suspicion.

How to avoid installation of malware?

Only download software from the developer's official website or a verified platform. Never use cracks, key generators, or pirated software - these are among the most common sources of malware. Be cautious with email attachments and links in messages, even when the sender appears familiar. Avoid clicking suspicious ads or pop-ups, and decline browser notification requests from sites you do not trust.

Keep the operating system and all installed applications updated to patch security vulnerabilities that attackers could exploit. Use a reputable antivirus or anti-malware program and scan your computer 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.

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.
