The PDF file was flagged for containing a link to a known malicious redirector. This indicates a likely attempt to lure the user to a harmful website. The document body was unreadable, but the presence of the malicious URL is sufficient evidence for this assessment. 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%92%D0%B5%D0%B3%D0%B0+312+%D1%81%D1%82%D0%B5%D1%80%D0%B5%D0%BE+%D1%81%D1%85%D0%B5%D0%BC%D0%B0&charset=utf-8
