The PDF file contains a link to a known malicious redirector. This indicates the document's primary purpose is to lure the user to a harmful website. The redirector URL is http://botcraftman.ru/?lip&keyword=%D0%B6%D1%83%D1%80%D0%BD%D0%B0%D0%BB+%D0%B2%D1%8B%D0%B4%D0%B0%D1%87%D0%B8+%D0%B8+%D0%B2%D0%BE%D0%B7%D0%B2%D1%80%D0%B0%D1%82%D0%B0+%D0%BA%D0%BB%D1%8E%D1%87%D0%B5%D0%B9+%D0%BE%D1%82+%D1%8D%D0%BB%D0%B5%D0%BA%D1%82%D1%80%D0%BE%D1%83%D1%81%D1%82%D0%B0%D0%BD%D0%BE%D0%B2%D0%BE%D0%BA+%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C&charset=utf-8. No scripts were extracted, and the document body was heavily obfuscated, limiting further analysis of the document's specific content.

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.
