MITRE ATT&CK
T1204 Malicious Link T1059 Command and Scripting Interpreter

The PDF file contains an embedded script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic and the presence of an embedded binary artifact. The ML classifier and ClamAV detection strongly suggest malicious intent, likely exploiting a vulnerability within PDF rendering to execute this script. The XFA form structure further supports this, as XFA is known to be used in PDF exploits. The embedded script is the primary mechanism for the attack, likely leading to further malicious activity.

  • 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.
