The PDF file was flagged for containing a link to a known malicious redirector infrastructure. The embedded URL 'http://botcraftman.ru/...' is the primary indicator of malicious intent. No scripts were extracted, and the document body was heavily obfuscated, preventing further analysis of the document's specific lure.

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%83%D1%81%D0%B8%D0%BB%D0%B8%D1%82%D0%B5%D0%BB%D1%8C+%D0%BC%D0%BE%D1%89%D0%BD%D0%BE%D1%81%D1%82%D0%B8+%D0%BD%D0%B0+%D0%B3%D1%83+81&charset=utf-8
