T1204 Malicious Link
T1204.002 Malicious Link: Malicious File
The critical ClamAV detection 'Pdf.Exploit.Dropped-78' and the 'PDF_EMBEDDED_SCRIPT_PAYLOAD' heuristic indicate that this PDF contains an embedded script designed to exploit a vulnerability and deliver a secondary payload. The presence of XFA form elements and embedded files further supports this. The embedded URLs are related to XFA schemas and Adobe, but their reputation is unknown or benign, suggesting they are not the primary malicious indicators.

-
ClamAV: Pdf.Exploit.Dropped-78 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Exploit.Dropped-78
-
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/
