The PDF file contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.cc/wix?keyword=bizzleberry+soraka+guide'. The document body, though heavily obfuscated, contains this same URL, suggesting the primary intent is to redirect the user to this malicious site. No scripts were extracted, and the document body's content is largely unreadable, but the presence of the malicious URL is a strong indicator of a phishing or redirection attack.

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.
