The PDF file was flagged by a critical heuristic for linking to known malicious redirector infrastructure. The ML classifier also strongly indicated maliciousness. The embedded URL `http://botcraftman.ru/...` is the primary indicator of compromise, suggesting the document's purpose is to lure the user to this malicious site. No scripts were extracted, and the document body was not parsable as human-readable text.

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%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B4%D1%80%D0%B0%D0%B9%D0%B2%D0%B5%D1%80%D0%B0+%D0%B4%D0%BB%D1%8F+dell+inspiron+1501+%D0%B4%D0%BB%D1%8F+windows+7&charset=utf-8
