Yunit is malware that is classified as a stealer. This malicious program operates by extracting and exfiltrating data from systems and applications. Stealers can also have other capabilities, ranging from file theft to recording content.
Yunit malware overview
Yunit is a piece of malicious software designed to steal information. Stealers collect system and personal data. These programs can obtain information from various installed apps. For example, from browsers – stealers may seek browsing and search engine histories, Internet cookies, usernames/passwords, personally identifiable details, credit/debit card numbers, and so forth.
Other programs are also targeted, most commonly password managers, email clients, messengers, FTP (File Transfer Protocol) clients, gaming-related software, VPN (Virtual Private Network) clients, cryptocurrency wallets, etc. Sought information and applications can differ between such programs.
The target list of Yunit is currently unknown, and it might differ between potential variants. Additionally, stealers may possess other functionalities.
To elaborate, they might take screenshots, live-stream desktops, record audio/video via microphones/cameras, or perform other spying activities (spyware); download victims' files (grabbers); record keystrokes (keyloggers); steal clipboard content or replace it (clippers); and so on.
It is pertinent to mention that malware developers often improve upon their creations or techniques. Therefore, possible future versions of Yunit could have additional/different capabilities.
To summarize, the presence of malicious software like Yunit on devices can lead to severe privacy issues, financial losses, and identity theft.

Stealer-type malware examples
We have written about thousands of malicious programs; SMD69, Amnesia, BlackNote, Crystal, and Vilsa are merely some of our newest articles on stealers. Programs within this class can collect a wide variety of information or only specific details. Data-stealing abilities are prevalent in other types of malware as well.
However, regardless of what (if any) information that malicious software targets – its presence on a system endangers device and user safety. Therefore, all threats must be eliminated immediately upon detection.
How did Yunit infiltrate my computer?
At the time of writing, Yunit's developers are promoting it on Telegram. Hence, how it is spread might differ depending on the cyber criminals using this stealer (i.e., techniques may vary between attacks).
Generally, malware is proliferated using phishing and social engineering tactics. Commonly, malicious programs are disguised as or bundled with ordinary content. Infectious files come in various formats, e.g., archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), documents (Microsoft Office, Microsoft OneNote, PDF, etc.), JavaScript, and so forth.
The most widespread malware distribution methods include: drive-by (stealthy/deceptive) downloads, malicious attachments or links in spam emails/messages, online scams, malvertising, untrustworthy download sources (e.g., freeware and third-party sites, Peer-to-Peer sharing networks, etc.), illegal software activation tools ("cracks"), and fake updates.
Furthermore, some malicious programs can self-spread via local networks and removable storage devices (e.g., external hard drives, USB flash drives, etc.).
How to avoid installation of malware?
We strongly recommend exercising caution when browsing since fraudulent and dangerous online content typically appears genuine and harmless. Incoming emails, DMs/PMs, SMSes, and other messages must be approached with care. Attachments or links found in suspect/irrelevant mail must not be opened, as they can be infectious.
Another recommendation is to download only from official and verified channels. Additionally, all programs must be activated and updated using legitimate functions/tools, as those acquired from third-parties can contain malware.
We must emphasize the importance of having a reputable anti-virus installed and kept up-to-date. Security software 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.

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.
