The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection 'Pdf.Exploit.Agent-36014' strongly suggests a known exploit. The extracted artifact 'javascript_obj0013_001.js' shows script obfuscation, typical of malware attempting to hide its malicious actions. The primary function of the embedded script is likely to download and execute a secondary payload, which is a common technique for initial access and further infection.
