The PDF file contains a link to a known malicious redirector, botcraftman.ru. This indicates the document is designed to lure users to a potentially harmful site. The embedded URL is the primary indicator of malicious intent. No scripts were extracted, limiting further analysis of the payload.

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+windows+7+ultimate+32+bit+%D1%82%D0%BE%D1%80%D1%80%D0%B5%D0%BD%D1%82+%D0%BE%D1%80%D0%B8%D0%B3%D0%B8%D0%BD%D0%B0%D0%BB&charset=utf-8
