The PDF was flagged by multiple high-confidence heuristics, including a critical ClamAV detection (Pdf.Exploit.Agent-6136306-0) and an ML classifier indicating maliciousness. The presence of an XFA form and an embedded script payload strongly suggests an exploit attempt. The embedded script is likely responsible for downloading and executing a second-stage payload, though its exact functionality could not be fully determined due to obfuscation.

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.
-
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/
