MITRE ATT&CK
T1204.002 Malicious File T1566.001 Spearphishing Attachment

The critical ClamAV detection 'Pdf.Exploit.Dropped-78' strongly indicates malicious intent. The PDF contains an embedded script payload and an embedded file, suggesting it's designed to exploit vulnerabilities and drop further malware. The presence of XFA form elements and embedded files are common characteristics of exploit-laden PDFs.

Heuristics 5

  • ClamAV: Pdf.Exploit.Dropped-78 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Dropped-78
  • 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.
  • 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
  • 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.
