MITRE ATT&CK
T1059.001 JavaScript/JScript

The PDF file contains embedded JavaScript, indicated by the 'PDF_JAVASCRIPT' and 'PDF_JS' heuristics. The 'ClamAV_DETECTION' heuristic identifies it as 'Pdf.Exploit.Agent-36121', suggesting it's a known exploit. The embedded JavaScript is the primary mechanism for exploitation, likely intended to download and execute a secondary payload. Due to the lack of specific script content and the obfuscated nature of the PDF body, the exact payload and delivery mechanism remain unclear.
