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

The critical ClamAV detection of 'Pdf.Exploit.Agent-36962' strongly indicates a PDF exploit. The presence of embedded files and an XFA form further supports this, suggesting the document is designed to trigger an exploit. The embedded URL, while benign in reputation, is associated with the document's structure and may be part of the exploit chain.

Heuristics 5

  • ClamAV: Pdf.Exploit.Agent-36962 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Agent-36962
  • Embedded file low PDF_EMBEDDED
    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • AcroForm button with action trigger low PDF_ACROFORM_BUTTON
    PDF contains a /Btn form field together with a SubmitForm/URI/Launch/JS trigger — this is the building block of fake 'Download' or 'Open' button overlays used in PDF phishing lures
  • 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.
