The PDF file contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL `http://botcraftman.ru/?lip&keyword=%D0%BA%D0%BB%D1%8E%D1%87+%D0%B4%D0%BB%D1%8F+dead+rising+2&charset=utf-8` is the primary indicator of malicious intent. This suggests the document is designed to lure users to a potentially harmful website. No scripts were extracted, and the document body was heavily truncated and unreadable.

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.
