T1566.001 Spearphishing Attachment

The presence of these lures suggests an attempt to trick users into downloading further malicious content or visiting malicious sites, likely delivered as a spearphishing attachment.

  • 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.
