Heuristics 4

  • 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.
  • Cracked-software lure uses shortlink/download gateway critical PDF_CRACKED_SOFTWARE_SHORTLINK_LURE
    PDF visible text advertises a crack, serial number, archive, or pirated-software download and pairs it with a shortlink or encoded download gateway. This is a high-confidence social-engineering carrier for unwanted software or droppers; the PDF itself is not a parser exploit.
  • 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.
