The PDF was flagged by multiple heuristics, including a critical ClamAV detection for 'Pdf.Exploit.Agent-6136306-0', and an ML classifier with a very high confidence score. The presence of an XFA form and an embedded script payload indicates a likely exploit attempt. The document body content, though heavily obfuscated, appears to be a lure related to Google, possibly for phishing or credential harvesting.

  • 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.
