MITRE ATT&CK

T1204.002 Malicious File 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 a known exploit. The extracted JavaScript file, 'javascript_obj0013_001.js', shows signs of obfuscation, typical for malware attempting to hide its malicious actions. The primary function of this script is likely to download and execute a secondary payload, which is a common attack vector for PDF-based malware.
