The PDF file contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL, http://botcraftman.ru/..., is the primary indicator of malicious intent. No scripts were extracted, and the document body was not sufficiently readable to provide further context. The file is likely used as a lure to direct users to a malicious site.

Heuristics 2

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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.
    URL http://botcraftman.ru/?lip&keyword=%D0%B0%D0%BD%D0%B3%D0%BB%D0%B8%D0%B9%D1%81%D0%BA%D0%B8%D0%B9+%D0%BF%D0%BE+%D0%B4%D1%80%D0%B0%D0%B3%D1%83%D0%BD%D0%BA%D0%B8%D0%BD%D1%83+%D0%B0%D1%83%D0%B4%D0%B8%D0%BE%D0%BA%D1%83%D1%80%D1%81+%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B1%D0%B5%D1%81%D0%BF%D0%BB%D0%B0%D1%82%D0%BD%D0%BE&charset=utf-8
