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' and the suspicious extracted artifact 'javascript_obj0013_001.js' with obfuscation indicators further support malicious intent. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload, a common technique for PDF-based malware.
