The PDF file contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL `http://botcraftman.ru/...` is identified as the primary indicator of malicious activity. No scripts were extracted from this sample, limiting the analysis of its specific payload delivery mechanism. The file's purpose is inferred to be a lure for phishing or malware distribution.

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%9C%D0%B0%D0%B9%D0%BD%D0%BA%D1%80%D0%B0%D1%84%D1%82+%D0%B7%D0%BE%D0%BC%D0%B1%D0%B8+%D0%B0%D0%BF%D0%BE%D0%BA%D0%B0%D0%BB%D0%B8%D0%BF%D1%81%D0%B8%D1%81+%D1%81+%D0%BE%D1%80%D1%83%D0%B6%D0%B8%D0%B5%D0%BC+%D0%B8%D0%B3%D1%80%D0%B0%D1%82%D1%8C&charset=utf-8
