The PDF file was flagged by a machine learning classifier and contains a critical heuristic indicating a link to known malicious redirector infrastructure. The embedded URL, https://ttraff.com/wix?keyword=transformers+2+all+decepticons+names, is the primary indicator of malicious intent. No scripts were extracted, and the document body was heavily obfuscated, making it difficult to determine the exact lure or payload.

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.
