TrapStealer malware overview

After successfully infiltrating a system, TrapStealer starts collecting device data, like its name, graphics card details, installed anti-virus tools, and so forth.

This stealer uses anti-detection and anti-analysis functionalities. It utilizes anti-debugging measures and can self-terminate after concluding its malicious activities. Additionally, this malware can masquerade as a Discord Nitro generator or a webhook tool. TrapStealer can automatically start upon system boot. It can also hide windows (specifically, Command Prompt) and cause Blue Screen of Death errors.

As mentioned in the introduction, this stealer has several capabilities centering on Discord. The malicious program can disable this messaging platform and self-inject into its processes. TrapStealer seeks to obtain a variety of information from Discord, including tokens, username/password, global username, email, telephone number, friend lists, guild/server data, etc.

This stealer, like most programs within this classification, also targets browser data. From Google Chrome, Mozilla Firefox, Microsoft Edge, Opera, Opera GX, Brave, Safari, Internet Explorer, and other popular browsers – TrapStealer can extract and exfiltrate browsing and search engine histories, Internet cookies, autofills, saved passwords, etc.

The stealer likewise targets information related to the WhatsApp messenger and sessions from the Steam video game service platform. Other TrapStealer's capabilities include taking screenshots, stealing content copied into the clipboard (copy-paste buffer), and exfiltrating (downloading) files based on predetermined extensions and customized keywords.

It must be mentioned that malware developers commonly improve upon their software and methodologies. TrapStealer has already had several updates, and future versions are not unlikely – hence, this malware may have an expanded target list or additional/different features later on.

In summary, the presence of software like TrapStealer on systems can result in severe privacy issues, financial losses, and even identity theft.

Stealer-type malware examples

PovertyLumarBlazeStealer, and qBit are just some examples of stealers that we have researched recently. This malware can seek to extract specific details or a broad range of data. Furthermore, the capabilities of malicious software are not limited to its classification.

It must be stressed that regardless of how malware operates – its presence on a system threatens device integrity and user safety. Therefore, it is paramount to eliminate all threats immediately upon detection.

How did TrapStealer infiltrate my computer?

TrapStealer has been observed being promoted by its developers on the GitHub repository. Hence, its distribution can vary based on the methods preferred by the cyber criminals using it at the time.

Malware is typically presented as or bundled with ordinary content. Virulent files can be archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), documents (Microsoft Office, Microsoft OneNote, PDF, etc.), JavaScript, and so forth. When a malicious file is executed, run, or otherwise opened – the infection process is initiated.

Phishing and social engineering tactics are widely used in malware distribution. The most commonly used proliferation methods include: drive-by (stealthy/deceptive) downloads, online scams, malicious attachments or links in spam emails/messages, untrustworthy download channels (e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, etc.), malvertising, illegal software activation ("cracking") tools, and fake updates.

Some malicious programs can even self-spread through local networks and removable storage devices (e.g., USB flash drives, external hard drives, etc.).

How to avoid installation of malware?

We strongly recommend caution with incoming emails, PMs/DMs, SMSes, and other messages. Attachments or links present in dubious/irrelevant mail must not be opened, as they can be infectious. It is important to be vigilant while browsing since fake and malicious online content usually appears genuine and innocuous.

Furthermore, all downloads must be performed from official and verified sources. Another recommendation is to activate and update programs by using legitimate functions/tools, as those obtained from third-parties may contain malware.

We must emphasize that having a reputable anti-virus installed and kept updated is paramount to device/user safety. Security software must be used to run regular system scans and to remove detected threats. 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.

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".

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. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

Search for malware and delete 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.
