T1204.002 Malicious Link: Malicious File
The file is identified as malicious by multiple heuristics, including a critical ClamAV detection (Pdf.Exploit.Dropped-78) and a high ML score. The PDF contains embedded content and XFA forms, which are common vectors for exploits. While no specific script was extracted, the presence of embedded files and URLs suggests an attempt to download and execute a secondary 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.
-
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/
