T1204.002 Malicious File
T1059.001 PowerShell
The PDF file contains an embedded script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic. ClamAV detection as 'Pdf.Exploit.Dropped-156969-1' strongly suggests it's designed to exploit a vulnerability. The embedded file artifact further supports the payload delivery mechanism. The document body text is largely unreadable due to encoding or truncation, but the presence of XFA forms and embedded content points towards a malicious exploit delivery.

ClamAV: Pdf.Exploit.Dropped-156969-1 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Exploit.Dropped-156969-1
-
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.
-
Embedded file low PDF_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
