The PDF file was identified as malicious due to the presence of a link to a known malicious redirector. This suggests the document is designed to lure users to a potentially harmful website. No scripts were extracted, and the document body was unreadable, limiting further analysis of the specific lure. The primary IOC is the malicious redirector URL.

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%BF%D1%80%D0%B0%D0%B2%D0%BA%D0%B0+2%D0%BD%D0%B4%D1%84%D0%BB+%D0%B7%D0%B0+2013%D0%B3+%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B1%D0%BB%D0%B0%D0%BD%D0%BA&charset=utf-8
