MITRE ATT&CK
T1204.002 Malicious File: User Execution: Malicious Attachment T1553.005 Subversion: Mark-of-the-Web Bypass

The PDF file was detected by ClamAV as Pdf.Exploit.Agent-36830, indicating a known exploit. It contains embedded content and an embedded script payload, suggesting it's designed to execute malicious code upon opening. The embedded file artifact further supports the delivery of a secondary payload.

Heuristics 6

  • ClamAV: Pdf.Exploit.Agent-36830 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Agent-36830
  • ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV
    ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
  • 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.
