The PDF file contains a critical heuristic firing indicating a link to a known malicious redirector. The embedded URL http://botcraftman.ru/?lip&keyword=battlefield+bad+company+2+%D0%BA%D0%BB%D1%8E%D1%87+%D0%B0%D0%BA%D1%82%D0%B8%D0%B2%D0%B0%D1%86%D0%B8%D0%B8&charset=utf-8 is the primary indicator of malicious intent. The document body appears to be heavily obfuscated or corrupted, preventing a clear understanding of its content, but the presence of the malicious URL is sufficient to classify it as a malicious redirector. No scripts were extracted from this sample.

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.
