MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual download button lure, strongly suggesting a phishing or malware distribution attempt. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of external URIs and the document's deceptive content indicate it's designed to trick users into downloading further malicious content.

  • 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.
