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

The PDF contains embedded content and a script payload, as indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic. ClamAV detected this as Pdf.Exploit.Dropped-78, suggesting it's designed to drop or execute further malware. The embedded script, though partially obfuscated, likely facilitates the execution of the embedded file, which is a common technique for delivering second-stage payloads.

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.
