The PDF file contains a link to a known malicious redirector. This indicates an attempt to lure the user to a harmful website, likely for further exploitation or credential harvesting. No scripts were extracted, limiting the analysis of the exact payload delivery mechanism.

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=%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D1%82%D1%80%D0%B0%D0%BD%D1%81+%D0%BB%D1%83%D1%87%D1%88%D0%B5%D0%B5&charset=utf-8
