MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.007 JavaScript

The file is a PDF that contains an embedded XFA form and triggers the CVE-2010-0188 exploit, which is known to deliver malicious payloads. The embedded JavaScript within the XFA form likely facilitates the execution of this exploit. While the exact payload is not fully discernible due to truncation, the exploit and embedded script strongly indicate malicious intent for client execution.

  • ClamAV: Pdf.Exploit.Agent-6136306-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Agent-6136306-0
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • Embedded script payload in PDF stream low 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 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.
