What kind of malware is Lu0bot?
Lu0bot is a piece of malicious software. The malware is lightweight, so its usage of system resources is low. This complicates Lu0bot's detection, as it does not cause significant symptoms, like a severe decline in system performance.
The malicious program operates as a telemetry harvester. However, such malware typically has additional heinous functionalities. Hence, it is likely that Lu0bot does as well.
Lu0bot in detail
Lu0bot targets data relating to the infected machine, e.g., network, processing, and other similar information. If certain parameters are met, this malicious program also checks whether the device is running an old Microsoft Windows version. Hence, it is probable that Lu0bot can operate on these versions (e.g., Windows XP and Windows Vista) as well.
However, malware like Lu0bot often have even more malicious features. Additionally, software of this type can be updated with additional harmful functions.
Typically, these programs also seek to obtain users' personal information, e.g., personally identifiable details, account/platform log-in credentials (IDs, email addresses, usernames, and passwords), banking data (bank account details and credit card numbers), and so on.
This information can be used to steal the victim's identity and ask their contacts/friends/followers on social platforms for loans and donations. Cyber criminals can use finance-related data to make fraudulent monetary transactions and/or unauthorized online purchases.
Should compromising and/or particularly sensitive information be found on data storage accounts or the infected machine (depending on the malicious program's capabilities), it can be held for ransom under threat of publication.
Information-stealing malware can acquire data by downloading it from the compromised machine, extracting it from browses and other installed applications, and/or by recording it (e.g., taking screenshots, keylogging, using attached/integrated microphones and cameras, etc.).
It is not uncommon for such malware to be able to cause chain infections (i.e., download/install additional malicious programs) or give and execute commands on the device.
To summarize, Lu0bot infections can result in severe privacy issues, financial losses, and identity theft. If it is suspected or known that Lu0bot (or other malware) has already infected the system - an anti-virus must be used to remove it without delay.

Malware in general
Jupyter, Mini-Redline, Little Thief, and Ducky are some examples of malware that has data-stealing abilities. Malicious programs can have a broad range of functionalities, which can be in varied combinations.
Aside from collecting information, other common features include (but are not limited to): establishing remote access and control over infected machines (RATs - Remote Access Trojans), causing chain infections (downloading/installing additional malware), encrypting data and/or locking the device's screen for ransom purposes (ransomware), using system resources to generate cryptocurrency (cryptominers).
Regardless of how malicious software operates, it poses a serious threat to device integrity and user safety. It is highly recommended to remove all system infections immediately upon detection.
How did Lu0bot infiltrate my computer?
Malware is distributed using a wide variety of techniques and tactics. Untrustworthy download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - are commonly used to spread malware.
Malicious programs are usually downloaded/installed inadvertently, as they are often disguised as or bundled with ordinary software/media.
Illegal activation tools ("cracks") and fake updates are prime examples of malware-proliferating content. "Cracking" tools can cause infections instead of activating licensed software. Illegitimate updaters infect systems by abusing flaws of outdated products and/or by installing malicious programs rather than the promised updates.
Malware is also distributed via spam campaigns - mass-scale operations during which thousands of deceptive/scam emails are sent. These letters are typically presented as "urgent", "important", "priority", and/or as mail from genuine companies, institutions, organizations, service providers, and other entities.
How to avoid installation of malware?
It is recommended to always use official and verified download sources. Additionally, all programs must be activated and updated with tools/functions provided by legitimate developers.
To avoid infecting the system via spam mail, it is advised against opening dubious and irrelevant emails - especially any attachments or links present in them.
It is crucial to have a reputable anti-virus/anti-spyware suite installed and kept up-to-date. This software has to be used to run 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.
Update September 27, 2023 – new variant of Lu0bot has been discovered. It is written in Node.js and, as such, is a cross-platform malware. It implements heavily obfuscated code. The operation of this program remains largely the same. This version is capable of receiving commands from its C&C (Command and Control) server. More information on these developments can be found in an article on the ANY.RUN blog.

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.

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.
