This link, http://botcraftman.ru/?lip&keyword=%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D1%88%D1%80%D0%B8%D1%84%D1%82+romul&charset=utf-8, is the primary indicator of malicious intent. The document's purpose is to lure the user to this external site, which is known to host malicious content or facilitate further attacks.

Heuristics 2

  • 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.
