Possible damage

Information-stealing malware is a type of malicious software designed to gather sensitive information from a victim's computer or mobile device. Once the malware is installed, it will often run in the background, collecting data and sending it back to the attacker's command and control server.

Some types of information-stealing malware are capable of evading detection by security software or other forms of protection, making them particularly dangerous. Examples of different information stealers are Atlantida Stealer, S1deload Stealer, and VenusStealer.

How did WhiteSnake infiltrate my computer?

A computer becomes infected when a user opens a spam email that contains an executable file disguised as a PDF document. When the user runs this file, it drops another file that executes a PowerShell script, leading to a download and installation of malware on the victim's computer.

Also, attackers can place malicious ads on legitimate websites that can infect a user's computer when clicked, use social engineering tactics, exploit vulnerabilities in web browsers or other software, and use other ways to trick users into installing malware.

How to avoid installation of malware?

Be cautious when opening emails (links or files with emaisl) or downloading files from unknown/shady sources. Keep installed software up-to-date with the latest security patches, and use a reputable antivirus or anti-malware program to scan your device regularly. Also, do not trust ads on shady pages.

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.

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.
