More about Luna Grabber

Luna Grabber is designed as malicious software with the purpose of extracting data from web browsers, the Discord application, and local system details. Additionally, it incorporates typical traits found in harmful programs, like the capability to identify its execution within a virtual environment and a self-destruct function.

Luna Grabber is highly customizable. Attackers can tailor it to perform various tasks. The creator's tool lets cybercriminals easily set Luna Grabber up to start automatically when a computer turns on, gather data like Wi-Fi information and even 2FA codes, and even access details from games like Minecraft.

Luna Grabber poses significant threats and potential damages. This malicious software is designed to silently steal personal and sensitive information from various sources on the victim's computer. This includes data from web browsers, potentially compromising login credentials, financial information, private communication, personal accounts, and more.

If the victim uses the Discord application, Luna Grabber can also pilfer information from there, potentially exposing personal conversations and sensitive data. The malware can also gather local system details, providing the attacker with insights into the victim's device and potentially allowing them to exploit vulnerabilities.

Moreover, Luna Grabber's ability to detect virtual environments and its self-destruct function indicates a level of sophistication that makes it harder to detect and remove. This could lead to prolonged exposure and continued data theft.

How did Luna Grabber infiltrate my computer?

Cybercriminals spread Luna Grabber by tricking developers who make scripts for Roblox games. They use a real tool called "noblox.js" that lets gamers make various things with code. However, threat actors made fake versions of this tool that look real but secretly steal info. So, when developers use the fake tool, it takes their info without them knowing.

Malware can also spread in other ways, such as through deceptive emails containing harmful attachments or links, compromised websites that automatically download malware, and software vulnerabilities that attackers exploit.

Malicious drive-by downloads can occur just by visiting infected websites while sharing files from untrustworthy sources or using peer-to-peer networks can also lead to malware infections. Additionally, attackers may manipulate users into downloading malware through social engineering tactics or abuse legitimate tools to carry out their malicious activities.

How to avoid installation of malware?

Only download software, files, and apps from reputable and official sources. Avoid pirated or cracked software. Keep your operating system, installed software (including antivirus program) up to date. Avoid opening email attachments or clicking on links from unknown or suspicious addresses. Be especially wary of unexpected attachments or urgent messages.

Be cautious when visiting unfamiliar websites or clicking on ads. 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.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

Delete malware in Autoruns

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.

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.
