The PDF file contains a link to a known malicious redirector, botcraftman.ru. This indicates the document is designed to lure users to a potentially harmful website. The file's metadata shows it was generated by wkhtmltopdf, a tool often used to create malicious PDFs. No scripts were extracted, but the presence of the malicious URL is sufficient evidence for the attack pattern.

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.
