MITRE ATT&CK

T1204.002 Malicious File: User Execution: Malicious File T1566.002 Phishing: Spearphishing Attachment

The ML classifier strongly indicates this PDF is malicious. It contains embedded content and an embedded script payload, suggesting it's designed to deliver a secondary exploit or malware. The presence of XFA form elements further supports its suspicious nature. The embedded URLs are not directly actionable for the attack but are part of the PDF structure.

Heuristics 4

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
Embedded URL info EMBEDDED_URL

One 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.
