The PDF contains a large number of embedded links to external PDF files, a technique often used for SEO poisoning or to drive traffic to malicious sites. The ML classifier also flagged this document as malicious. No scripts were extracted from this sample, and the document body was heavily obfuscated, preventing a deeper analysis of its specific intent beyond link farming.

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.
