The PDF contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL points to 'botcraftman.ru', which is flagged as malicious. No scripts were extracted, but the presence of a malicious redirector link strongly suggests an attempt to lure the user to a harmful site, likely for phishing or malware distribution.

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.
