MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that lure users into downloading potentially malicious files by promising free in-game items. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs indicates an attempt to redirect the user to a download site. No scripts were extracted, but the overall pattern suggests a phishing or scam attempt.

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