MITRE ATT&CK
T1204.002 Malicious File T1553.005 Mark-of-the-Web Bypass

The PDF contains embedded content and an embedded script payload, as indicated by the PDF_EMBEDDED and PDF_EMBEDDED_SCRIPT_PAYLOAD heuristics. ClamAV detection further confirms its malicious nature. The embedded script is obfuscated and difficult to analyze, but its presence suggests the PDF is designed to download and execute a second-stage payload. The embedded URLs are related to XFA forms, which are sometimes used in PDF exploits.

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.
