Written by Tomas Meskauskas on (updated)
What is Prynt Stealer?
Prynt is a stealer-type malicious program, which our research team found while inspecting malware selling hotspots. This piece of malicious software is designed to obtain a wide variety of sensitive information from infected systems. Prynt Stealer has multiple functionalities that allow it to exfiltrate, extract, record, and alter various content.
Prynt Stealer malware overview
According to Prynt Stealer's promotional material, there are different builds and payment plans for this program. Its developers present it as a versatile and highly customizable stealer, with continuous support and updates available for the buyers.
Prynt Stealer can steal varied data and uses multiple functionalities to do so. It collects device and system information, e.g., Windows product key, IP address/ geolocation, installed applications, running processes, user account data, saved Wi-Fi passwords, etc. This malicious program can take screenshots and webcam snapshots.
Prynt Stealer can also download small (less than 5.12 KB size) document, image, database, and source code files (full list of targeted formats).
From browsers (full list), this stealer can extract browsing history, download data, bookmarks, Internet cookies, autofills, usernames/passwords, and credit card numbers. Additionally, this malware searches for keywords associated with banking, cryptocurrency, and pornography.
Prynt Stealer employs multiple features to acquire finance-related information. However, the latter suggests that the attackers may use the program for sextortion - either by leveraging explicit material obtained through spying or by crafting detailed scams targeting the victim without actually having any compromising content (e.g., footage featuring the victim).
Prynt Stealer can extract data from a broad range of mail clients, messengers, FTP clients, VPNs, gaming-related apps, and cryptocurrency wallets (full list of targeted applications).
This stealer also has clipper abilities. Clippers are designed to change the data copied into the clipboard (copy-paste buffer). Hence, Prynt Stealer can be used to redirect outgoing cryptocurrency transactions by changing the cryptowallet addresses copied into the clipboard - so that those belonging to the attackers would be pasted instead. Thereby, the funds would get transferred to the cyber criminals rather than the intended recipients.
To summarize, Prynt Stealer infections can lead to severe privacy issues, financial losses, and identity theft. If you suspect that your system is already infected with Prynt Stealer (or other malware) - we strongly advise using an anti-virus to eliminate it without delay.

Stealer-type malware examples
We have analyzed thousands of information-stealing malware samples. Stealer-types are quite popular, and 000 Stealer, ColdStealer, FFDroider, and Lightning Stealer are a few examples of those we have researched recently.
Generally, malicious software can have various abilities in different combinations. Functionalities relating to data theft are especially prevalent. However, regardless of how malware operates - its presence on a system endangers device integrity and user safety. Therefore, we highly recommend removing threats immediately upon detection.
How did Prynt Stealer infiltrate my computer?
Since different cyber criminals can use Prynt Stealer, how it is distributed depends on the specific attackers. The most common malware distribution techniques include: drive-by (stealthy and deceptive) downloads, malicious attachments and links in spam emails and messages, dubious download channels (e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc.), illegal program activation ("cracking") tools, online scams, and fake updates.
Malicious software is often disguised as or bundled with regular programs/media. Virulent files can be executables (.exe, .run, etc.), archives (ZIP, RAR, etc.), PDF and Microsoft Office documents, JavaScript, and so on. Once a malicious file is opened - the infection process is triggered.
How to avoid installation of malware?
We recommend downloading only from official and verified sources. Furthermore, software must be activated and updated using tools provided by genuine developers, as those acquired from third-parties (e.g., illegal activation tools - cracks, illegitimate updaters, etc.) may contain malware.
We advise against opening the attachments and links present in suspicious/irrelevant emails and messages - since that may result in a system infection.
It is crucial to have a reputable anti-virus installed and updated. Security programs must be used to run regular system scans and to remove detected threats/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.

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.
