The PDF file contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL `http://botcraftman.ru/...` is identified as malicious. While no scripts were extracted, the presence of this malicious link strongly suggests the document's purpose is to redirect users to a harmful destination, likely for phishing or malware delivery.

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.
