The PDF contains a large number of embedded links to external websites, a technique often used for SEO spam or to redirect users to malicious content. The ML classifier strongly indicated maliciousness. No scripts were extracted from this sample, and the document body was unreadable, limiting further analysis of the specific lure. The primary attack pattern observed is the mass linking to external domains.

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.
