MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.007 JavaScript

The PDF document contains an embedded JavaScript payload, indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic and the presence of script content. The ML classifier and ClamAV detection strongly suggest malicious intent, likely involving exploitation for client execution. The script itself appears to be heavily obfuscated, but its structure and the embedded nature suggest it is designed to download and execute a secondary payload.

    ClamAV detected this file as malware: Pdf.Exploit.Agent-6136306-0
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • Embedded script payload in PDF stream low 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.
  • 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.
