The PDF file contains a link to a known malicious redirector. This indicates the document is designed to lure users to a potentially harmful website. The embedded URL http://botcraftman.ru/?lip&keyword=%D1%81%D1%85%D0%B5%D0%BC%D0%B0+%D0%BC%D0%B5%D1%82%D1%80%D0%BE+%D0%BC%D0%BE%D1%81%D0%BA%D0%B2%D1%8B+%D0%B4%D0%BB%D1%8F+%D0%BF%D0%B5%D1%87%D0%B0%D1%82%D0%B8&charset=utf-8 is the primary indicator of malicious intent. No scripts were extracted, limiting the analysis of further actions.

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.
