The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic, which is indicative of a phishing or malware distribution attempt. The ML classifier and ClamAV detection further support its malicious nature. The embedded URLs are likely intended to redirect users to malicious content, such as the linked PDF files.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
