The PDF file contains a critical heuristic firing for a malicious redirector link pointing to 'http://botcraftman.ru/'. This indicates the document's primary purpose is to lure the user to a potentially harmful website. No scripts were extracted, and the document body was heavily obfuscated, preventing further analysis of its specific content or intent beyond the redirection.

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%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B0%D0%B8%D0%BC+%D0%B4%D0%BB%D1%8F+samp+03x&charset=utf-8
