The PDF contains a large number of embedded links to external PDF files hosted on a dynamic DNS domain, identified by the PDF_SEO_LINK_FARM heuristic. While no scripts were explicitly extracted, the nature of the embedded links suggests a potential for SEO manipulation or the distribution of further malicious content. The ML classifier also flagged this PDF as malicious with high confidence.

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.
