MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded script content, indicated by the PDF_EMBEDDED_SCRIPT_PAYLOAD heuristic. ClamAV detection as Pdf.Malware.Agent-10043167-0 further confirms its malicious nature. The presence of XFA forms (PDF_XFA) suggests a complex document structure likely used to conceal or deliver the malicious script. The embedded script is suspected to download and execute a second-stage payload.

Heuristics 5

  • ClamAV: Pdf.Malware.Agent-10043167-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Malware.Agent-10043167-0
  • 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.
