MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URI that directs users to a suspicious domain, likely for downloading unwanted software or engaging in a scam. The ML classifier strongly flagged this PDF as malicious, and the presence of a visual download button further supports a malicious intent. Although no scripts were explicitly extracted, the PDF structure and embedded URLs suggest a phishing or social engineering attack.

  • 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.
