T1204.002 Malicious File: User Execution: Malicious File T1566.002 Phishing: Spearphishing Attachment

The PDF file contains an embedded script payload and triggers XFA form heuristics, indicating it's designed to exploit vulnerabilities. ClamAV detection confirms its malicious nature, identifying it as Pdf.Exploit.Agent-6136306-0. The embedded script likely downloads and executes a second-stage payload, though its exact function 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.
