MITRE ATT&CK
T1059.007 JavaScript T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF file contains embedded JavaScript, indicated by the 'PDF_EMBEDDED_SCRIPT_PAYLOAD' heuristic and the presence of script content within the XFA template. The ClamAV detection 'Pdf.Exploit.Agent-6136306-0' strongly suggests malicious intent, likely involving the execution of an exploit. The embedded script is heavily obfuscated and truncated, but its structure suggests it attempts to download and execute a second-stage payload. The benign URLs present are likely decoys or standard XFA schema references.

Heuristics 4

  • 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.
