  • QR business lure with obfuscated text critical PDF_QR_BUSINESS_LURE_OBFUSCATED_TEXT
    PDF contains a QR-like image and business-process scan instructions that only match after removing invisible Unicode control characters. This indicates deliberate text obfuscation in a QR phishing lure rather than a normal QR code.
  • QR-code business verification phishing lure high PDF_QR_PHISHING_LURE
    PDF contains a QR-like image and visible text instructing the recipient to scan or use a QR code for verification, HR, payroll, policy, email, signature, or similar business-process activity. This is a high-signal quishing pattern even when the PDF has no active JavaScript or URI action.
  • Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARM
    Small PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.
  • 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
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
  • 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.
