The PDF file contains a link to a known malicious redirector, indicating an attempt to lure the user to a harmful site. The embedded URL is the primary indicator of malicious intent. No scripts were extracted, and the document body was not parsable.

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%A1%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D1%87%D0%B8%D1%82+minecraft-aoe+100&charset=utf-8
