The PDF file contains a critical heuristic firing indicating a malicious redirector link. The embedded URL points to 'botcraftman.ru', which is flagged as malicious. This suggests the document's primary purpose is to lure the user to this site, likely for further exploitation or credential harvesting. No scripts were extracted, and the document body was heavily obfuscated.

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.
