T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains heuristics indicating it impersonates a cloud document lure and features a visual download button. An embedded URI points to a suspicious external URL, likely intended for a malicious download. The document body was unreadable, but the heuristics strongly suggest a social engineering attack to trick the user into downloading a payload.

Heuristics 4

  • Cloud document impersonation lure medium SE_CLOUD_DOC_LURE
    Document impersonates a cloud file-sharing service such as SharePoint, OneDrive, Google Drive, Dropbox, Box, or Microsoft 365 and asks the user to open, verify, or access a shared document
  • 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.
