The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV detection as 'Pdf.Exploit.Agent-36014' strongly suggests exploitation of a known PDF vulnerability. The extracted JavaScript file, 'javascript_obj0013_001.js', shows signs of obfuscation, typical of malware attempting to hide its payload. The overall attack pattern involves luring a user to open a malicious PDF which then triggers the embedded script for further compromise.
