T1203 Exploitation for Client Execution
T1059.007 JavaScript
The PDF sample was flagged by multiple heuristics, including ML classification and ClamAV, indicating malicious intent. The presence of an embedded script payload and XFA form suggests an exploit is being used to achieve arbitrary code execution. While the specific exploit is not detailed, the embedded file and script point towards a downloader or dropper functionality.

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 script payload in PDF stream low 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.
