The PDF file contains a link to a known malicious redirector, http://botcraftman.ru/, which is indicative of a phishing or malware distribution attempt. The file was generated by wkhtmltopdf, suggesting it might be a crafted document rather than a typical user-generated one. No scripts were extracted, but the presence of the malicious URL is sufficient evidence for this assessment.

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.
