MITRE ATT&CK

T1204.002 Malicious File: User Execution: Malicious JavaScript

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection 'Pdf.Exploit.Agent-36014' strongly suggests this JavaScript is malicious and exploits a vulnerability within the PDF reader. The extracted JavaScript file, 'javascript_obj0013_001.js', likely contains the exploit code. The exact function of the script could not be determined due to obfuscation, but it is highly probable that it attempts to download and execute a second-stage payload.
