MITRE ATT&CK

T1059.007 JavaScript T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The PDF file contains an embedded XFA form and a JavaScript payload, flagged by heuristics and ClamAV as malicious. The JavaScript appears to be obfuscated and attempts to download and execute further content, indicated by the ML classifier's high confidence and the ClamAV detection name. The embedded URLs are benign, and no other IOCs were extracted.

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.
