The PDF file contains a heuristic firing indicating it links to known malicious redirector infrastructure. The embedded URL `http://botcraftman.ru/...` is identified as a malicious redirector. While no scripts were extracted, the presence of a malicious link suggests an attempt to lure the user to a compromised site, likely for further exploitation or credential harvesting.

Heuristics 2

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

  • 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.
