MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and a visual download button lure, strongly suggesting an attempt to trick the user into downloading a secondary payload. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were directly extracted, the presence of embedded URIs and the overall structure point towards a phishing or social engineering attack aimed at delivering malware.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
