The PDF was flagged by a machine learning classifier with high confidence as malicious. Heuristics indicate the presence of an embedded script payload and an embedded file, suggesting it is designed to deliver a secondary payload or exploit a vulnerability. The document body contains garbled text, which is common in obfuscated malicious documents.

Heuristics 3

Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD

PDF 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_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
