MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and document body text that mimic download lures for popular games, aiming to trick users into clicking malicious links. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to download further content. No scripts were extracted, but the overall pattern indicates a phishing or malware distribution attempt.

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