MITRE ATT&CK
T1059.001 PowerShell

The PDF was flagged by multiple heuristics, including a critical ClamAV detection for 'Pdf.Exploit.Agent-6136306-0' and an ML classifier indicating high maliciousness. The presence of an XFA form and an embedded script payload suggests an exploit targeting PDF reader vulnerabilities. The embedded script likely attempts to download and execute a second-stage payload, though its exact functionality is obscured by the PDF structure.

    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.
