MITRE ATT&CK
T1204.002 Malicious File: User Execution: Malicious PDF T1059.001 Command and Scripting Interpreter: PowerShell

The PDF file contains an embedded script payload within an XFA form, as indicated by the PDF_XFA and PDF_EMBEDDED_SCRIPT_PAYLOAD heuristics. ClamAV detection confirms its malicious nature as Pdf.Exploit.Agent-6136306-0. The embedded script is likely responsible for executing the exploit, leading to the download and execution of a second-stage payload. The confidence is high due to multiple strong indicators, but the family remains unknown as no specific indicators point to a known variant.

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.
