MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The file is identified as a malicious PDF by ClamAV with the signature Pdf.Exploit.Agent-36962. It contains embedded files and an XFA form, which are common vectors for PDF exploits. The presence of an embedded URL suggests a potential download or redirection mechanism. The exact nature of the exploit is not fully detailed, but the critical ClamAV detection and embedded artifacts strongly indicate an attempt to compromise the user's system.

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.
