T1204.002 Malicious File: User Execution: Malicious File
T1566.002 Phishing: Spearphishing Attachment
This PDF sample was flagged as malicious by an ML classifier with high confidence. Heuristics indicate the presence of an embedded script payload within a PDF stream, a common technique for delivering malicious content. While no specific document body text was extracted for content analysis, the presence of embedded scripts and the overall PDF structure strongly suggest an attack pattern aimed at exploiting the user or the PDF reader.

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/
