MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The PDF utilizes XFA forms, a known vector for exploits. An embedded script payload was detected, and ML classifiers strongly indicate maliciousness. ClamAV also identified this as Pdf.Exploit.Agent-6136306-0. The embedded script is likely responsible for executing the malicious payload, though its exact function is obscured by the PDF structure.

  • 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.
