MITRE ATT&CK

T1204.002 Malicious File T1059.001 PowerShell

The PDF contains an embedded script payload and an embedded file, strongly indicating malicious intent. The ML classifier also flagged this PDF with a very high probability of being malicious. The embedded script appears to be obfuscated JavaScript that likely attempts to download and execute a second-stage payload, though the exact URL is not directly reconstructible from the provided snippet.

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.
