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

The critical ClamAV heuristic 'Pdf.Exploit.Dropped-78' indicates the file is a known PDF exploit. The presence of an embedded script payload and an embedded file further supports this. The embedded URLs are benign or unknown, and no document body text was available for analysis. The exact nature of the exploit and payload cannot be determined without further analysis of the embedded artifact.

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.
