T1059.001 PowerShell
T1204.002 Malicious File
The PDF file contains an embedded script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic and the presence of an embedded PDF script artifact. The ML classifier and ClamAV detection strongly suggest malicious intent, likely exploiting a known PDF vulnerability (Pdf.Exploit.Agent-6136306-0). The XFA form further supports this, as XFA forms are sometimes used to host exploits. The embedded script is likely responsible for downloading and executing a second-stage payload.

Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOADPDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
