MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF sample was flagged by a machine learning classifier as malicious with high confidence. It contains an embedded script payload and an embedded file, indicating it is designed to deliver a secondary exploit or malware. The presence of XFA form elements and an AcroForm button with an action trigger further suggests an attempt to execute code or redirect the user.

Heuristics 5

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
AcroForm button with action trigger low PDF_ACROFORM_BUTTON

PDF contains a /Btn form field together with a SubmitForm/URI/Launch/JS trigger — this is the building block of fake 'Download' or 'Open' button overlays used in PDF phishing lures
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.
