The PDF file contains a heuristic firing indicating a malicious redirector link. The embedded URL `http://botcraftman.ru/...` is identified as a known malicious redirector. This suggests the document is designed to lure users to a malicious site, likely for further exploitation or credential harvesting. No scripts were extracted, limiting the analysis of the exact payload.

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.
