The PDF file was flagged as malicious by a machine learning classifier and contains a critical heuristic indicating a malicious redirector link. The embedded link directs to 'ttraff.me', a known malicious redirector. The document body, though heavily obfuscated, contains the same malicious URL, suggesting the document's primary purpose is to lure users to this malicious site.

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.
