The PDF contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various PDF files hosted on different domains. This suggests a link farm or redirection strategy. The ClamAV detection as Pdf.Phishing.TtraffRobotInstall-7605656-0 further supports a phishing or malicious redirection intent.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
