The PDF file contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL, https://ttraff.cc/wb?keyword=joyo%20kanji%20list%20pdf, is likely used to obscure the final destination, which could be a phishing page or a malware download. The document body itself is heavily obfuscated and contains metadata related to its creation, but does not provide clear user-facing content. No scripts were extracted from this sample.

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.
