The PDF file was flagged by a machine learning classifier as malicious and contains a link to a known malicious redirector. The redirector URL is designed to lure users with a search query for installing FIFA 13 on Windows 7, likely leading to a phishing or malware download page. No scripts were extracted, and the document body was truncated, limiting further analysis of the exact 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.
