The PDF was flagged as malicious by ClamAV (Js.Exploit.HTML-30) and a machine learning classifier. High-severity heuristics indicate the presence of risky executable script within an XFA form, specifically a numeric evaluation stager. This suggests the PDF is designed to exploit vulnerabilities or deliver a payload via its scripting capabilities. The embedded URL is likely part of the exploitation chain.

Heuristics 5
-
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.

ClamAV: Js.Exploit.HTML-30 critical CLAMAV_DETECTIONClamAV detected this file as malware: Js.Exploit.HTML-30
-
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
-
