Heuristics 3

  • PDF links to document on public blob storage high PDF_PUBLIC_BLOB_DOCUMENT_LINK
    PDF contains a clickable action to a document payload hosted on public blob/object storage. Shared object storage can be used legitimately, so this rule is suspicious rather than conclusive unless paired with lure text or other phishing indicators.
  • 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.
