MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

This PDF document contains an embedded JavaScript payload within an XFA form, which is a known technique for exploiting PDF vulnerabilities. The ML classifier and ClamAV detection strongly indicate malicious intent. The embedded script is heavily obfuscated but appears designed to download and execute a secondary payload, as suggested by the heuristic firings and the nature of XFA exploits.

XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
Embedded script payload in PDF stream low 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 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.
