The PDF file was identified as malicious due to a critical heuristic firing for a link to a known malicious redirector. The embedded URL, http://botcraftman.ru/..., is the primary indicator of malicious intent. While no scripts were extracted, the presence of this malicious link suggests the document is designed to lure users to a harmful website, likely for phishing or malware delivery. The file was generated by wkhtmltopdf, which is not inherently malicious but can be used to create malicious documents.

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.
