The PDF file was flagged by a critical heuristic for containing a link to a known malicious redirector. The ML classifier also strongly indicated maliciousness. The embedded URL `http://botcraftman.ru/?lip&keyword=%D0%90%D1%83%D0%B4%D0%B8%D0%BE+%D1%81%D0%BA%D0%B0%D0%B7%D0%BA%D0%B8+%D0%BD%D0%B0+%D1%81%D0%B2%D0%B0%D0%B4%D1%8C%D0%B1%D1%83+%D0%BF%D1%80%D0%B8%D0%BA%D0%BE%D0%BB%D1%8C%D0%BD%D1%8B%D0%B5&charset=utf-8` is the primary indicator of malicious intent. No scripts were extracted, and the document body was truncated and unreadable, preventing further analysis of the lure.

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%90%D1%83%D0%B4%D0%B8%D0%BE+%D1%81%D0%BA%D0%B0%D0%B7%D0%BA%D0%B8+%D0%BD%D0%B0+%D1%81%D0%B2%D0%B0%D0%B4%D1%8C%D0%B1%D1%83+%D0%BF%D1%80%D0%B8%D0%BA%D0%BE%D0%BB%D1%8C%D0%BD%D1%8B%D0%B5&charset=utf-8
