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

The PDF was flagged by multiple high-confidence heuristics, including a critical ClamAV detection for 'Pdf.Exploit.Agent-6136306-0'. The presence of an embedded script payload strongly suggests it is designed to execute malicious code. The ML classifier output of 0.999994 further supports its malicious nature. The embedded URL is likely part of the exploit chain.

  • 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.
