T1059.001 PowerShell
The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV identified the file as Pdf.Dropper.Agent-7212398-0. The embedded JavaScript file, javascript_obj0013_001.js, is likely responsible for the malicious behavior, potentially downloading and executing a second-stage payload. The document body is unreadable, so the rationale is based on the heuristics and embedded artifact.
