The PDF contains multiple heuristics indicating malicious intent, including a hidden HTML iframe and an external URI pointing to a suspicious domain. The embedded links and the hidden iframe likely serve to redirect the user to a compromised website, potentially for further exploitation or credential harvesting. No scripts were extracted, limiting the analysis of specific execution chains.

Heuristics 3

  • PDF contains hidden external HTML iframe high PDF_HIDDEN_HTML_IFRAME
    PDF bytes contain a hidden zero-size HTML iframe pointing to an external HTTP(S) URL. This is a strong malicious dropper/redirect indicator and is not expected in ordinary PDF content.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
