T1059.001 PowerShell T1204.002 Malicious File

The critical ClamAV heuristic indicates the file is malicious, specifically identified as 'Pdf.Exploit.Agent-36128'. Low-severity heuristics confirm the presence of embedded JavaScript within the PDF structure. While the document body is uninformative, the presence of JavaScript actions and streams strongly suggests an exploit is being used to execute code. The primary attack vector appears to be leveraging a PDF vulnerability to run malicious JavaScript, which is commonly used to download and execute further stages of malware.
