Heuristics 5

  • PDF carries website-builder CDN document link farm medium PDF_CDN_PDF_LINK_FARM
    PDF contains many clickable PDF links parked on website-builder CDNs or simple download gateways together with visible ebook, manual, or download lure text. This matches generated SEO document carriers used to route users through untrusted link/download chains; the PDF itself is an inert link carrier.
  • PDF links to disposable redirector campaign host medium PDF_DISPOSABLE_REDIRECTOR_CAMPAIGN
    PDF's outbound link points to a throwaway redirector domain that recurs as the sole redirect across a large family of otherwise unrelated spam PDFs (movie-piracy, affiliate, and viral-link lures). These domains appear on no reputable list and exist only to funnel openers into malvertising / scam / download chains.
  • Urgency / deadline lure low SE_URGENCY_LURE
    Document contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
  • 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.
