MITRE ATT&CK
T1059.001 JavaScript/JScript

The PDF contains embedded JavaScript, as indicated by the PDF_JAVASCRIPT heuristic. The ML classifier and ClamAV detection strongly suggest malicious intent, likely exploiting a vulnerability to execute this script. The script's exact function is obscured, but its presence is the primary indicator of malicious activity.

Heuristics 4

  • ClamAV: Pdf.Exploit.Agent-35606 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Agent-35606
  • JavaScript action low PDF_JAVASCRIPT
    PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • PDF differential parser failed info PDF_DIFFERENTIAL_PARSE_FAILED
    The cross-check parser (pdfminer.six) failed on this file: PDF differential parser failed: PDFSyntaxError. Static heuristics still ran and any of their findings above are valid; only the differential cross-check signal is missing.
  • 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.
