The PDF file contains a link to a known malicious redirector, http://botcraftman.ru/. This indicates an attempt to lure the user to a malicious site, likely for further exploitation or credential harvesting. No scripts were extracted, and the document body was not sufficiently readable to determine a specific lure.

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%92%D0%B5%D1%80%D0%BE%D0%BD%D0%B8%D0%BA%D0%B0+%D0%B5%D1%81%D0%BA%D0%B8%D0%BD%D0%B0+%D0%BE%D0%BC%D1%81%D0%BA&charset=utf-8
