The PDF file was flagged by a critical heuristic for linking to known malicious redirector infrastructure. The ML classifier also assigned a high probability of maliciousness. The embedded URL points to 'botcraftman.ru', which is associated with malicious redirection. No scripts were extracted, but the presence of a malicious link indicates a likely attempt to lure the user to a harmful site.

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%B8%D0%BD%D1%81%D1%82%D1%80%D1%83%D0%BA%D1%86%D0%B8%D1%8F+%D0%BF%D0%BE+%D0%BE%D1%85%D1%80%D0%B0%D0%BD%D0%B5+%D1%82%D1%80%D1%83%D0%B4%D0%B0+%D0%B4%D0%BB%D1%8F+%D0%B2%D1%80%D0%B0%D1%87%D0%B0+%D0%BA%D0%B4%D0%BB&charset=utf-8
