The PDF file contains a critical heuristic firing indicating a link to a known malicious redirector. The embedded URL, http://botcraftman.ru/..., is the primary indicator of malicious intent. While no scripts were extracted, the presence of this malicious link strongly suggests the document is designed to redirect users to a harmful destination, likely for phishing or malware delivery. The document body was heavily truncated and unreadable, preventing further analysis of its content.

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%B8%D0%BC%D1%83%D0%BB%D1%8F%D1%82%D0%BE%D1%80+%D1%81%D0%BE%D1%80%D1%82%D0%B8%D1%80%D0%BE%D0%B2%D0%BE%D1%87%D0%BD%D0%BE%D0%B9+%D1%81%D1%82%D0%B0%D0%BD%D1%86%D0%B8%D0%B8&charset=utf-8
