The PDF document contains embedded JavaScript, indicated by multiple heuristic firings. The presence of 'stream_000_off00000060.js' and 'stream_092_off0000b757.js' suggests that these JavaScript streams are the primary mechanism for malicious activity. The JavaScript is likely designed to download and execute a second-stage payload, although the exact functionality is obscured by the embedded nature and potential obfuscation.

Heuristics 5

  • JavaScript action low 1 related finding PDF_JAVASCRIPT
    PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules. (matched inside decoded stream)
  • Embedded JS stream low PDF_JS
    PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules. (matched inside decoded stream)
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic (matched inside decoded stream)
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • 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.
