MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF contains embedded script content, flagged by heuristics as a malicious payload. The ML classifier strongly indicates maliciousness. The embedded script likely attempts to exploit a vulnerability within the PDF reader to execute arbitrary code, potentially leading to further compromise. The document body contains obfuscated JavaScript-like code, further supporting the script execution vector.

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.
