MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains an embedded script payload within an XFA form, as indicated by the PDF_XFA and PDF_EMBEDDED_SCRIPT_PAYLOAD heuristics. ClamAV also detected this file as Pdf.Exploit.Agent-6136306-0. The embedded script is likely responsible for executing the malicious payload, although its exact function cannot be determined due to obfuscation. The embedded URLs are not directly actionable for malicious intent.

    ClamAV detected this file as malware: Pdf.Exploit.Agent-6136306-0
  • 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.
