BlazeStealer malware overview

According to BlazeStealer's promotional material, it has anti-detection and anti-analysis functionalities. The malware is presented as being undetectable by anti-virus tools, but that is untrue based on the information available on the VirusTotal platform. This stealer is also promoted as a wholly obfuscated malware with anti-debugging features.

Stealers tend to target browser data, e.g., browsing and search engine histories, Internet cookies, auto-fills, stored passwords, saved credit card numbers, etc. Other applications can be targeted in this manner as well, e.g., social networking, messaging, money transferring, cryptocurrency wallets, data storage, file transferring, streaming, gaming, and so on. Some stealers have additional capabilities.

The malware may possess grabber functionality that is used to exfiltrate (download) system/user files. Keylogging (recording keystrokes), taking screenshots, and recording audio/video via microphones and cameras – can be among stealer functionalities.

It is likewise worth mentioning that malware developers commonly improve upon their creations. Hence, potential future variants of BlazeStealer could have different capabilities.

To summarize, the presence of software like BlazeStealer on devices can lead to serious privacy issues, financial losses, and even identity theft.

Stealer-type malware examples

qBitDarkEyeEasyStealerExela, and Fewer are just some examples of stealers. Malware designed to collect data can target incredibly specific details or a broad range of information.

Malicious software is not limited in functionality to its category; this software can have a variety of capabilities in different combinations. However, regardless of how malware operates – its presence on a system threatens device integrity and user safety. Hence, all threats must be eliminated immediately upon detection.

How did BlazeStealer infiltrate my computer?

At the time of research, BlazeStealer was sold on the Internet for $15.99 or $10.99 with a discount. Due to this, how this stealer is proliferated depends on the cyber criminals using it.

The most widely used techniques include phishing and social engineering. Malicious software is typically disguised as or bundled with ordinary programs/media. Infectious files can be archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), documents (Microsoft Office, Microsoft OneNote, PDF, etc.), JavaScript, and so on.

The most widely used distribution methods include: drive-by (stealthy/deceptive) downloads, malicious attachments or links in spam mail (e.g., emails, DMs/PMs, SMSes, etc.), online scams, untrustworthy download sources (e.g., freeware and free file-hosting websites, Peer-to-Peer sharing networks, etc.), malvertising, illegal software activation tools ("cracks"), and fake updates.

Furthermore, some malicious programs can self-proliferate 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 being cautious while browsing since fake and dangerous online content usually appears legitimate and harmless. Another recommendation is to be careful with incoming emails and other messages. Attachments or links found in suspicious mail must not be opened, as they can be malicious.

We advise downloading only from official and verified channels. Additionally, all programs must be activated and updated using genuine functions/tools since 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 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.

manual malware removal step 5Check 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".

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.
