While no scripts were extracted, the structure and heuristics strongly suggest a malicious intent related to link manipulation or content distribution.

  • 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.
