This PDF file contains a large number of external links, a technique often used for SEO manipulation or to redirect users to malicious sites. The ML classifier strongly indicated maliciousness. No scripts were extracted, but the sheer volume of outbound links suggests a coordinated effort to drive traffic to potentially harmful destinations.

Heuristics 3

  • 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.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
