The PDF file was flagged as a malicious redirector due to its embedded link to http://botcraftman.ru/. This URL is known to point to malicious infrastructure, suggesting the document's purpose is to lure users to a harmful site. No scripts were extracted, and the document body was not sufficiently readable to determine a more specific lure.

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.
