MITRE ATT&CK
T1204.002 Malicious File T1059.007 JavaScript

The PDF utilizes XFA forms, a known vector for exploits. A critical ClamAV detection (Pdf.Exploit.Agent-6136306-0) confirms malicious intent. An embedded script payload was also identified, likely responsible for executing the exploit and delivering a secondary payload. The embedded URLs are not directly indicative of malicious activity but are part of the PDF's structure.

Heuristics 4

  • ClamAV: Pdf.Exploit.Agent-6136306-0 critical CLAMAV_DETECTION
    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.
