The PDF file was flagged by a machine learning classifier as malicious. It contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic.

The embedded URLs are likely intended to redirect users to potentially harmful content or to improve the search engine ranking of malicious sites.

Heuristics 2

  • 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.
