The PDF contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV detection as 'Pdf.Exploit.Agent-36014' further confirms its malicious nature. The embedded JavaScript is likely responsible for executing the exploit, potentially leading to further stages of attack. The document body is unreadable, so the rationale is based on the technical findings.
