MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains multiple embedded URLs and a visual download button lure, suggesting an attempt to trick users into downloading malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs indicates a potential download or redirection to a second-stage payload. No scripts were extracted from this sample, limiting the ability to determine specific execution methods.

  • 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.
