Heuristics 9

  • 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 links to a 'free generator / game hack' redirector critical PDF_GAME_HACK_REDIRECT_LURE
    PDF's clickable action targets a redirector of the form /app/<id>/<slug>-game-hack — the landing-page shape of a large SEO 'free spins / generator / game hack' lure family that funnels victims through rotating disposable hosts to a malware/scam payload. The multi-link variants also trip ML/link-farm rules; this catches the single-link variants that otherwise score clean. CRITICAL on its own: the /app/<id>/<slug>-game-hack path shape is unambiguous scam infra, and the host rotates so a host-list match can't be relied on.
  • Clipboard command execution lure high SE_CLIPBOARD_COMMAND_LURE
    Document tells the user to copy or paste clipboard content into Run, PowerShell, cmd, or another shell-like execution context
  • ClickFix social engineering attack high SE_CLICKFIX
    Document instructs the user to press Win+R or paste a command into a terminal — consistent with ClickFix attacks that bypass macro restrictions by tricking users into running malicious commands directly
  • Security software disable instruction high SE_SECURITY_BYPASS
    Document instructs the user to disable antivirus or security software — unusual for ordinary documents and high-risk in an unsolicited file
  • 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.
