The PDF file contains a link to a known malicious redirector, http://botcraftman.ru/. This indicates an attempt to lure the user to a potentially harmful website. The document body is truncated and does not provide further context, but the presence of the malicious URL is a strong indicator of malicious intent. No scripts were extracted from this sample.

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%BF%D0%B5%D1%80%D0%B5%D0%B2%D0%BE%D0%B4%D0%BD%D0%BE%D0%B9+%D1%8D%D0%BA%D0%B7%D0%B0%D0%BC%D0%B5%D0%BD+%D0%BF%D0%BE+%D0%B0%D0%BB%D0%B3%D0%B5%D0%B1%D1%80%D0%B5+7+%D0%BA%D0%BB%D0%B0%D1%81%D1%81+2015+%D0%B3%D0%BE%D0%B4+%D1%81+%D0%BE%D1%82%D0%B2%D0%B5%D1%82%D0%B0%D0%BC%D0%B8&charset=utf-8
