The PDF file was identified as malicious due to a critical heuristic firing for a link to known malicious redirector infrastructure. The embedded URL points to 'botcraftman.ru', which is flagged as a malicious redirector. This suggests the document is designed to lure users to a harmful website, likely for phishing or malware delivery. No scripts were extracted, and the document body was unreadable, limiting further analysis of the specific lure.

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%BA+%D1%81%D0%B4%D0%B5%D0%BB%D0%B0%D1%82%D1%8C+%D0%B2%D1%8B%D0%BA%D0%B8%D0%B4%D0%BD%D0%BE%D0%B9+%D0%BA%D0%BB%D1%8E%D1%87&charset=utf-8
