More about Prysmax

The Prysmax stealer is a sophisticated component of the malware designed with the capability to pilfer a wide array of sensitive information. It can stealthily extract data such as personal information, cryptocurrency details, passwords, cookies, Telegram and Discord sessions, credit card details, and other confidential information.

Also, the stealer can take screenshots, obtain the list of running processes and installed security solutions, and grab autofill data from browsers. Prysmax stealer can steal information from more than 20 browsers.

This comprehensive range of targeted data makes the Prysmax stealer a potent tool for unauthorized access to and acquisition of sensitive user information. Victims of a stealer infection may experience identity theft, financial loss, privacy breaches, compromised online accounts, and other issues.

The Remote Administration Trojan (RAT) provided by Prysmax delivers complete control over the victim's computer. With this powerful tool, attackers can gain unrestricted access, enabling them to install additional programs (including malware), exfiltrate files and passwords, and manipulate the network settings.

This level of control granted by the Prysmax RAT empowers malicious actors to not only monitor the victim's activities but also actively intervene and exploit the compromised system for their illicit purposes (e.g., ransomware deployment).

How did Prysmax infiltrate my computer?

Users may receive seemingly legitimate emails that contain malicious attachments or links. Clicking on these links or opening infected attachments can initiate a computer infection. Also, visiting compromised or malicious websites can expose users to harmful drive-by downloads.

Additionally, threat actors use fake pop-ups or notifications prompting users to update their software, malicious advertisements, software vulnerabilities, P2P networks, pirated software, third-party downloaders, and similar channels to distribute malware. More often than not, they rely on users downloading and executing malware by themselves.

It is known that Prysmax malware leverages vulnerabilities, specifically in PDF and Excel file formats, to execute a designated script upon opening. In practical terms, when a user opens a PDF or Excel file, the embedded script is triggered, allowing the malware to exploit the system.

How to avoid installation of malware?

Exercise caution with email attachments and links, especially from unknown or unexpected sources. Regularly update operating systems, software, and security applications. Be cautious when prompted to download software updates and only do so from official sources. Avoid visiting suspicious websites and be wary of unusual pop-ups or ads.

Do not download pirated software (or key generators and cracking tools). Use reputable security software and run system scans regularly. 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.
