The PDF file was flagged as a malicious redirector due to an embedded link pointing to botcraftman.ru. This URL is known to be associated with malicious redirection infrastructure. The file's metadata indicates it was generated by wkhtmltopdf, a tool often used to create malicious PDFs. No scripts were extracted, but the presence of the malicious URL is sufficient evidence for this assessment.

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%BF%D1%80%D0%B0%D0%B2%D0%BA%D0%B0+%D0%BE+%D0%B4%D0%BE%D1%85%D0%BE%D0%B4%D0%B0%D1%85+%D0%B2+%D1%86%D0%B5%D0%BD%D1%82%D1%80+%D0%B7%D0%B0%D0%BD%D1%8F%D1%82%D0%BE%D1%81%D1%82%D0%B8+%D0%BE%D0%B1%D1%80%D0%B0%D0%B7%D0%B5%D1%86+%D1%83%D0%BA%D1%80%D0%B0%D0%B8%D0%BD%D0%B0&charset=utf-8
