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

The file is a PDF document identified by ClamAV as Pdf.Exploit.Agent-6136306-0. It contains an embedded script payload within a PDF stream, indicating an attempt to execute malicious code upon opening. The XFA form detected suggests the exploit may leverage Adobe's XML Forms Architecture. The embedded script is likely responsible for downloading and executing a second-stage payload, though its exact functionality is obscured.

Heuristics 4

  • ClamAV: Pdf.Exploit.Agent-6136306-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Agent-6136306-0
  • 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.
  • 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.
