T1204.002 Malicious File
The PDF file was flagged as malicious by an ML classifier with high confidence. Heuristics indicate the presence of an embedded script payload within a PDF stream, suggesting it's designed to execute malicious code. The XFA form and embedded file indicators further support a complex attack vector. The embedded URLs, while not directly malicious, are part of the document's structure.

Heuristics 4
-
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
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL http://ns.adobe.com/xdp/
