MITRE ATT&CK

T1204.002 Malicious File: Malicious File

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 JavaScript file shows obfuscation, typical of malware attempting to hide its actions. The primary function of the script is likely to download and execute a secondary payload, which is a common attack vector for PDF-based exploits.
