MITRE ATT&CK
T1204.002 Malicious File: User Execution: Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection (Pdf.Exploit.Agent-36014) and the suspicious extracted artifact (javascript_obj0013_001.js) further suggest malicious intent. The embedded JavaScript is likely designed to download and execute a second-stage payload, a common technique for initial access and further system compromise.
