The PDF file contains a heuristic firing indicating it links to known malicious redirector infrastructure. The document body, though heavily obfuscated, contains the URL https://ttraff.ru/wix?keyword=tribez+and+castlez+guide, which is also listed as a malicious redirector. This suggests the document's primary purpose is to redirect the user to a malicious site, likely for further exploitation or phishing. No scripts were extracted, limiting the analysis of specific behaviors.

Heuristics 3

  • 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.
  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
