The PDF file contains a link to a known malicious redirector, botcraftman.ru. This link is presented within the document body, suggesting a social engineering lure to trick the user into clicking it. The URL itself contains keywords related to downloading a game, likely to increase user engagement. No scripts were extracted, and the document body was heavily truncated, limiting further 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.
