Technical Analysis
The Remote Administration Trojan (RAT) from Prysmax allows complete control over a victim’s computer. This powerful tool enables attackers to gain unrestricted access, facilitating the installation of additional programs (including malware), exfiltration of files and passwords, and alteration of network settings. The Prysmax RAT’s level of control enables malicious actors to monitor and actively intervene in the victim’s activities, using the compromised system for illicit purposes like deploying ransomware.
Spreading Methods
Prysmax malware often infiltrates computers through deceptive methods. Users might receive emails that seem legitimate but contain malicious attachments or links. The malware infects the computer when these links are clicked or the attachments are opened. Additionally, visiting compromised or malicious websites can lead to harmful drive-by downloads.
Moreover, cybercriminals distribute malware using fake pop-ups or notifications that trick users into believing they need a software update through malicious advertisements, exploiting software vulnerabilities, P2P networks, pirated software, third-party downloaders, and similar methods. Often, these tactics rely on users inadvertently downloading and executing the malware themselves.
Specifically, Prysmax malware is known to exploit vulnerabilities in PDF and Excel file formats. When a user opens a compromised PDF or Excel file, its embedded script is activated, enabling the malware to take advantage of the system’s vulnerabilities.
