The PDF was flagged by multiple heuristics, including a critical ClamAV detection for 'Pdf.Exploit.Agent-6136306-0' and a high ML score. The presence of an embedded script payload within an XFA form indicates an attempt to execute malicious code. While the specific exploit mechanism is not detailed, the XFA structure suggests a common vector for PDF-based attacks.

  • 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.
  • 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.
