MITRE ATT&CK

T1204.002 Malicious File T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file was flagged by a machine learning classifier as malicious with a high probability. Heuristics indicate the presence of embedded script payloads and embedded files, suggesting the document is designed to exploit vulnerabilities and deliver secondary malware. The embedded URL, while seemingly benign, is present within the document's structure, indicating a potential vector for further malicious activity.

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.
