T1204.002 Malicious File
T1566.002 Spearphishing Attachment
The PDF document contains embedded script content, as indicated by the 'PDF_EMBEDDED_SCRIPT_PAYLOAD' heuristic. The ML classifier also flagged this PDF as malicious with a high score. While the script content is heavily obfuscated and difficult to parse directly, its presence within an embedded object suggests it is intended to execute malicious code, likely to download and run a second-stage payload. The XFA form structure and embedded URLs are common in PDF-based attack vectors.

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/
