MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The PDF was flagged by multiple heuristics, including a critical ClamAV detection for 'Pdf.Exploit.Agent-6136306-0'. The presence of an XFA form and an embedded script payload indicates an attempt to exploit vulnerabilities or execute malicious code. The ML classifier strongly supports the malicious verdict. The embedded script is likely responsible for delivering the exploit payload.

  • 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.
