The PDF file was flagged as malicious due to the presence of a link to a known malicious redirector at http://botcraftman.ru/. This suggests the document is designed to lure users to a potentially harmful website. No scripts were extracted, and the document body was heavily obfuscated, preventing further analysis of its specific intent beyond the malicious link.

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%B2%D1%8F%D0%B7%D0%B0%D0%BD%D0%BD%D1%8B%D0%B5+%D1%81%D0%BB%D0%B5%D0%B4%D0%BA%D0%B8-%D1%81%D1%85%D0%B5%D0%BC%D0%B0+%D1%81%D0%BF%D0%B8%D1%86%D0%B0%D0%BC%D0%B8&charset=utf-8
