The PDF file contains a link to a known malicious redirector, botcraftman.ru. This heuristic indicates the document is designed to redirect users to a potentially harmful website. No scripts were extracted, and the document body was not sufficiently readable to determine a specific lure. The primary threat is the malicious link.

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=%D1%87%D0%B8%D1%82%D1%8B+%D0%B4%D0%BB%D1%8F+%D0%B8%D0%B3%D1%80%D1%8B+%D0%B3%D0%B5%D1%80%D0%BE%D0%B8+%D1%83%D0%B4%D0%B0%D1%80%D0%BD%D0%BE%D0%B3%D0%BE+%D0%BE%D1%82%D1%80%D1%8F%D0%B4%D0%B0+2&charset=utf-8
