MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The ClamAV detection for 'Heuristics.PDF.ObfuscatedNameObject' further suggests malicious intent. While the document body is unreadable, the presence of JavaScript points to an attempt to execute code, likely to download a second-stage payload or exploit a vulnerability. The embedded URLs are related to XFA forms, which are sometimes used in PDF exploits.
