Stealer-type malware examples

We have investigated thousands of malicious programs; SapphireStealerWise Remote stealer, and Agniane are just a couple examples of stealers we have written about recently.

Information-stealing malware can target specific details or a broad range of data. Furthermore, malicious software can have various types of capabilities. However, how malware operates is irrelevant since it endangers device integrity and user safety regardless. Therefore, all threats must be eliminated immediately upon detection.

How did Fewer infiltrate my computer?

At the time of writing, Fewer was promoted on hacker forums. Therefore, how it is proliferated depends on the cyber criminals using it at the time.

Generally, malware is spread by employing phishing and social engineering techniques. Malicious software is typically disguised as or bundled with ordinary program/media files. They can be archives (RAR, ZIP, etc.), executables (.exe, .run, etc.), documents (Microsoft Office, Microsoft OneNote, PDF, etc.), JavaScript, and so forth.

Malware is most widely distributed through drive-by (stealthy/deceptive) downloads, online scams, malicious attachments and links in spam mail (e.g., emails, DMs/PMs, SMSes, etc.), malvertising, untrustworthy download sources (e.g., freeware and free file-hosting websites, P2P sharing networks, etc.), illegal software activation ("cracking") tools, and fake updates.

What is more, 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 careful while browsing since fake and malicious online content usually appears legitimate and harmless. Caution must be extended to incoming emails and other messages. We advise against opening attachments or links found in suspect mail, as they can be virulent.

Furthermore, all downloads must be performed from official/verified channels. And all programs must be activated and updated using genuine functions/tools, as those obtained from third-parties may contain malware.

We must stress the importance of having a reputable anti-virus installed and kept updated. 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.

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.
