The PDF file contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL 'http://botcraftman.ru/?lip&keyword=%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B0%D0%B2%D0%B8%D0%B0%D1%81%D0%B8%D0%BC%D1%83%D0%BB%D1%8F%D1%82%D0%BE%D1%80+%D0%BF%D0%B0%D1%81%D1%81%D0%B0%D0%B6%D0%B8%D1%80%D1%81%D0%BA%D0%BE%D0%B3%D0%BE+%D1%81%D0%B0%D0%BC%D0%BE%D0%BB%D0%B5%D1%82%D0%B0+%D1%87%D0%B5%D1%80%D0%B5%D0%B7+%D1%82%D0%BE%D1%80%D1%80%D0%B5%D0%BD%D1%82&charset=utf-8' is the primary indicator of malicious intent. While no scripts were extracted, the presence of this malicious link suggests the PDF is designed to redirect users to a harmful destination.

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.
