T1059.007 JavaScript
T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The PDF file contains XFA forms with executable scripts, identified as a high-risk stager. ClamAV detected this as Js.Exploit.HTML-30, indicating it likely downloads and executes a second-stage payload via JavaScript. The embedded URL, while seemingly benign, is part of the XFA template structure and could be used in conjunction with the exploit.

-
XFA form contains risky executable script high PDF_XFA_SCRIPTPDF embeds an XFA form whose script block contains exploit, submission/launch, or shell-execution primitives. Ordinary LiveCycle print/update scripts are left as generic XFA/JS signals unless stronger behavior is present.

-
XFA numeric character-table eval stager high PDF_XFA_NUMERIC_EVAL_STAGERPDF XFA initialize script reads numeric form data from rawValue, maps the values through a short character table, and evals the reconstructed stage. This is an exploit-kit staging technique even when the final decoded layer remains encoded.

XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
