MITRE ATT&CK
T1204.002 Malicious File: User Execution: Malicious Attachment T1059.007 Abuse Execution: JavaScript

The PDF file contains an embedded script payload, flagged by heuristics and a machine learning classifier. ClamAV also detected it as a known exploit. The embedded script is likely responsible for downloading and executing a second-stage payload, contributing to the malicious nature of the document.

  • 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.
