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

The critical ClamAV detection 'Pdf.Exploit.Dropped-78' strongly indicates a malicious PDF exploiting a known vulnerability. The presence of an embedded script payload further supports this, suggesting the PDF is designed to download and execute a secondary malicious file. The embedded URLs are confirmed benign, and the document body content is not indicative of a specific lure.

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.
