The PDF file contains a critical heuristic firing indicating a link to a known malicious redirector. This suggests the document is designed to lure users to a malicious website. The embedded URL http://botcraftman.ru/... is the primary indicator of this malicious redirection. No scripts were extracted, and the document body was not sufficiently readable to provide further context.

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%A1%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D1%87%D0%B8%D1%82+%D0%BD%D0%B0+%D0%BA%D1%81+1+6+%D0%B0%D0%B8%D0%BC+%D0%B8+%D0%B2%D1%85&charset=utf-8
