The PDF file was identified as malicious due to the presence of a link to a known malicious redirector infrastructure at 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, limiting further analysis of the specific lure. The primary IOC is the malicious URL.

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%BA%D0%B0%D0%BD%D1%82%D0%BE%D1%80%D0%BE%D0%B2%D0%B8%D1%87+%D0%B0%D0%BB%D0%B5%D0%BA%D1%81%D0%B0%D0%BD%D0%B4%D1%80+%D0%B4%D0%B5%D1%81%D0%B0%D0%BD%D1%82+%D0%BF%D0%BE%D0%BF%D0%B0%D0%B4%D0%B0%D0%BD%D1%86%D0%B5%D0%B2+%D0%B0%D1%83%D0%B4%D0%B8%D0%BE%D0%BA%D0%BD%D0%B8%D0%B3%D0%B0&charset=utf-8
