This malware leverages a valid digital signature to enhance its credibility and avoid detection, allowing it to infiltrate user systems more effectively.\n\nOnce installed, the malicious software introduces a Node.js script that operates on the compromised machine. This script establishes periodic communication with a command and control (C2) server, enabling the threat actors to execute various commands remotely. The backdoor functionality of this malware poses significant risks, as it allows for unauthorized access and control over the user's system, potentially leading to further exploitation or data theft.",

This malware leverages a valid digital signature to enhance its credibility and avoid detection, allowing it to infiltrate user systems more effectively.\n\nOnce installed, the malicious software introduces a Node.js script that operates on the compromised machine. This script establishes periodic communication with a command and control (C2) server, enabling the threat actors to execute various commands remotely. The backdoor functionality of this malware poses significant risks, as it allows for unauthorized access and control over the user's system, potentially leading to further exploitation or data theft.",
