MITRE ATT&CK
T1204 Malicious Link T1204.002 Malicious File

The PDF file contains an embedded script payload and triggers heuristics related to XFA forms, indicating it's designed to exploit vulnerabilities. ClamAV detection confirms its malicious nature, identifying it as Pdf.Exploit.Agent-6136306-0. The embedded script is likely responsible for downloading and executing a second-stage payload, though its exact functionality is obscured by the PDF 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.
