Heuristics 5

  • PDF carries distributed game-hack scam link farm critical PDF_GAME_HACK_SEO_LINK_FARM
    PDF contains a free-generator/game-hack lure together with many external PDF links spread across distinct hosts whose filenames advertise game hacks, cheats, jailbreaks, generators, or free currency. This is a high-confidence scam/SEO-poisoning carrier: the PDF exists to route users into malicious or unwanted download/redirect chains, not to present normal document content.
  • PDF carries game-hack generator link farm medium PDF_GAME_HACK_LINK_FARM
    PDF contains a gaminggenerator.org app lure together with multiple external PDF links whose filenames advertise game hacks, cheats, jailbreaks, or generators. This is a lure/delivery link farm rather than a PDF exploit: the risk is the linked redirection chain.
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
