MITRE ATT&CK
T1059.001 JavaScript/JScript

The critical ClamAV heuristic 'Pdf.Exploit.Agent-36066' strongly indicates malicious activity. The presence of embedded JavaScript, identified by 'PDF_JAVASCRIPT' and 'PDF_JS' heuristics, suggests the file is designed to execute code. The JavaScript object, though large, is the primary mechanism for exploitation. The document body content is unreadable, providing no further context on the lure.
