MITRE ATT&CK
T1204 Malicious Link T1204.002 Malicious Link: Malicious File

The critical ClamAV heuristic 'Pdf.Exploit.Agent-36962' strongly indicates a PDF exploit. The presence of an embedded URL and multiple embedded files further supports the attack pattern of delivering a malicious payload. The XFA form and AcroForm button heuristics suggest the exploit may leverage interactive elements within the PDF.

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.
