The PDF contains a large number of embedded links to external PDF files, a technique often used for SEO manipulation or to distribute malicious content. While the ML classifier flagged this as malicious with high confidence, the specific URLs extracted are currently marked as benign. No scripts were extracted from this sample. The primary attack pattern observed is the creation of a link farm within the PDF document.

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.
