The PDF file contains a heuristic firing indicating a malicious redirector link. The embedded URL, 'https://ttraff.com/wix?keyword=yugioh+duelist+of+the+roses+fusion+guide', is the primary indicator of malicious intent, likely leading to a phishing or malware distribution site. The document body, though heavily obfuscated, contains this URL, reinforcing the malicious nature of the file.

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.
